Tivo Upgrade - first and most importantly, sometime over the last couple months, the folks at Tivo have finally figured out a software solution to the picture "pixelation" that was occurring with Verizon FiOS.  Sometime ago, my Tivo automatically updated to the latest 11.d version software and to test the upgrade, pulled all the attenuators out of the line.  Results: it works!

verizon_fios_250.jpgWith the picture quality issue now behind me, it was time to finally buy that second Tivo for the TV in our master bedroom.  It arrived a couple weeks ago and installation was much easier (now that I know the drill).  

By the way - one very important installation detail:  Tivo HD is shipped from the factory with an old version of software (really old), so you need to give it a day after you complete the initial configuration to perform the automatic software upgrade before worrying about the picture quality with Verizon FiOS.  Once the upgrade is completed, the picture quality should be corrected.  

I really love having two Tivos in the house now - the networking feature allows you to record on one Tivo and play back on the other.  Sounds silly, but it has already cured a couple domestic disputes in my household.  The choice between watching "Dancing with the Stars" or "How It's Made" had required moving to different rooms/TVs.  Now it doesn't matter which Tivo records the show, you can watch it on either one!

Closing Thoughts:
After all the original installation headaches, it seems to me that Tivo HD and Verizon FiOS are now working perfectly together.  Great user interface, built-in NetFlix client, fantastic picture quality - I finally have my peanut butter and chocolate!

If you have been following my now year-long adoption of Verizon FiOS, you know that we've been using a TiVo-HD with FiOS to record and watch television. We subscribe to the FiOS triple-play bundle with HDTV, 20Mbps Internet and two work telephone lines.  As in most households, my teen-age kids have been the primary users of the television all summer and I've been watching their behavior on how they use the television, what they watch and how much time they spend watching.

They spend hours in front of the TV, but they don't watch "TV".  No, they don't play video games - it's NetFlix over the Internet that has become their primary source of visual entertainment.  You see, the TiVo-HD includes an optional netflix-logo.jpgNetFlix on-demand client that allows the kids to choose programs from the vast NetFlix library and then watch them instantly on our TiVo via the Internet.  It really is amazing - no waiting for the DVD anymore - just click and watch.  The kids have even put the NetFlix mobile client on their iPod Touches, allowing them to browse the NetFlix library from the couch.  

So what does this mean to the Cable Industry?  Think about it - here is a generation that who's world is a broadband connected and able to access virtually any/all information almost instantly.  And most of that information comes from other sources, not the cable operator.  Based on their usage, the cable operator is just a supplier of broadband Internet.

This really means that when the millennials grow up and start controlling household spending, things will change dramatically.  Our generation values the TV programming, Telephone, then Internet in that order.  I suspect they will reverse it, with their highest value being the Internet and then TV and Telephone being almost irrelevant.

Where does this take both the cable companies and legacy wireline operators?   Their focus will soon need to shift to reliable and very high-speed Internet access being the "high value and primary product", because the rest is quickly going the way of the Dodo bird.

My week started with a discussion of the future of voice services on cable networks and a live demonstration during the CableLabs Innovation Showcase, highlighting  a number of audio clips that showed the difference between the existing narrow-band voice quality and what the same clips sound like with HD VoIP.  During my presentation, I challenged the cable operators in attendance that unless they do something to differentiate their voice services, that wireline telephony will soon fade into oblivion, taking away an important revenue stream from their services, turning the "triple play" into a "double play".  I was joined by Larry Clarkson, Product Marketing for the AudioCodes System Group who helped me present a number of architecture diagrams showing how HD will be integrated into the current and future network infrastructure.  We wrapped up with a demo featuring a live transcoding demonstration of a wide-band call between a Nokia E71 mobile, a DECT phone and AudioCodes 320HD phones.

Tuesday's main theater session is "High Definition Voice" featuring a panel of experts including Jean-Francois Mule, CableLabs; Vivek Badranith, France Telecom; Mike Jablon, Time Warner Cable and Jeff Pulver, Pulver.com.  During this member's only-event, the panel planned to discuss the current status of HD voice services to help the cable operator community assess their plans for HD in their networks.

Looking ahead, HD Voip will also be the topic of discussion at a number of other upcoming events, including:

ITExpo West in Los Angeles - "Pushing the Envelope with HD Voice - a State-of-the-Industry Panel Discussion" on Wednesday September 2nd at 10:30 AM

HD Communications Summit in New York City, an all-day event focused on HD in voice communications on Tuesday, September 15th in the New World Stages venue.

VON Fall 2009 in Miami Beach - "HD Voice: The Future of VoIP? A panel discussion on the impact of HD on our industry" on Wednesday, September 23rd at 12 noon.

I hope you will join me and participate in one or more of these sessions to contribute to this industry-changing discussion.

As with national and global politics, getting people with diverse needs and existing investments to compromise is a significant challenge.

So how do we break the almost infinite cycle of continuous interoperability testing between the growing number of hardware vendors, software applications and carriers?

One approach that immediately comes to mind is to define a "gold standard" that each of the market participants can test against, and create a predictable level of interoperability assurance between systems. As one of my readers duly noted, this is the driving vision of the SIP Forum, and their SIPconnect effort, trying to make SIP Trunking interoperability more predictable. The SIPconnect Technical Recommendation 1.0 specifies the interface between a SIP-enabled Service Provider to a SIP-enabled Enterprise Network (aka "SIP Trunks"). The specification essentially narrows the hundreds of valid options within SIP to a defined set for one application, the replacement of legacy PRI circuits. So far so good, but don't get too comfortable quite yet.

The down-side of SIPconnect (or any other interoperability standard) is as a side effect, it limits the services and options available to users of the systems. Think SIP handcuffs--great as long as you aren't the one wearing them. Features like security, network call transfers, voice messaging, fax, hosted PBX functions, dealing with NAT and other areas were in many cases outside the 1.0 specification and thus not supported. So back to the drawing board, extending the SIPconnect specification to 1.1, which is an ongoing development effort trying to add these important capabilities without ruining the simplicity of the 1.0 specification.

But remember that SIPconnect is only focused on SIP Trunking and doesn't address interoperability between SIP systems within an enterprise or service provider. We've already seen cases where enterprises have one vendor for their SIP-based IVR and another vendor for their IP-PBX, and legacy TDM messaging systems, and are trying to integrate all these together. (Acquisitions and mergers have a funny way of making strange bed-fellows.) In this particular case, they couldn't even get the vendors of these systems to talk to each other, let alone actually fix protocol compatibility issues.

With pure SIP-based applications expanding in market share and perfectly good legacy TDM systems that are too new to replace, I believe intra-enterprise interoperability issues will become much more common. In the end, I envision that enterprises will need a on-premise network element from an independent vendor that will provide interoperability and security between their legacy systems, SIP systems and SIP Trunks they depend on for connectivity. Right now, it appears a Session Border Controller (security and SIP interoperability) and/or a Media Gateway (TDM interoperability) is the best way to solve many of the difficult interoperability issues facing SIP. Trying to get competing vendors to talk seems to be an exercise in futility.

Next we'll discuss who should be responsible for interoperability and security with SIP Trunking--the service provider or the enterprise?

(Part II) http://blog.tmcnet.com/sip-invite/sip/sip-interoperability-why-is-it-so-hard-to-achieve-part-ii.html 41049@http://blog.tmcnet.com/sip-invite/  Earlier this week I shared with you a few thoughts on SIP Interoperability discussing what I felt where the root causes of incompatibility between two or more SIP-based systems.  I clearly hit a raw nerve with a few of you, flooding my email box with your own stories of interoperability issues.   You shared with me your own experiences with registration problems, call transfers, security, message waiting indications, even fax issues.  It seems the couple examples I gave were only the tip of the iceberg.

 SIP Interop - Slide2.PNG

Let's move past the technical issues with SIP Interoperability and talk about a far more difficult challenge - the politics of SIP Interoperability.

 It appears to me that soon after the authors of RFC 3261 finished their work, the fun really started.  As the development teams of the various product and application companies started to build their solutions based on RFC 3261, the looseness of the specification allowed them to make wildly different choices all "within specification".   The result was that you had developers that had invested untold hours of hard work into developing a protocol stack that worked fine in their own lab and with their own products, but had serious interoperability issues with other vendors.  To each of the developers, it appeared that "everybody else screwed up". 

 So now you have a number of over-worked developers that would have to go back into their products and re-work significant parts of their SIP stacks - just because someone else made some bad choices.  The end result is a classic stand-off with each of the vendors saying "we followed the spec, you should change".  So much for "Open and Standard".

 SIP Interop - Slide15.PNG

To make things even more politically complex, many of the vendors are starting to compete in the marketplace, vying for the same markets and customers.  In this competitive environment, interoperability is a double-edge sword.

 Okay, so let's pretend our developers get past their own stubbornness and decide to make some changes to be more interoperable.  Who do you do your interoperability testing with?  Do you test against anyone that comes along?  Or maybe just in cases where "the business case works"?   What happens if you or anyone else makes changes?  Do you re-test with everyone?  It was easy when there were just a few other applications to test with on the market, but now with hundreds of applications and devices to test, it becomes clear that the maintenance of SIP interoperability testing becomes a bigger burden than the original development. 

 So, how do we work around these political problems and break the cycle of continuous interoperability testing?  This will be the topic of my next post.

(Part I) http://blog.tmcnet.com/sip-invite/sip/sip-interoperability---why-is-it-so-hard-to-achieve-part-i.html 41024@http://blog.tmcnet.com/sip-invite/ For those of you that have deployed SIP-based solutions or SIP Trunking, there is a pretty good chance that you've had to navigate your way through the maze of SIP interoperability, wondering why it is so difficult to get a straight answer out of anyone on whether two systems will work together or not.

SIP is supposed to be a standard and eliminate many of the challenges with integrating systems from various vendors together, right? If my IP-PBX is RFC 3261 compliant and my SIP Trunking service provider is RFC 3261 compliant, they should just work, correct? Well--maybe or maybe not. Most likely there will be interoperability issues.

Today I thought it would be good to start a multi-part series of posts to explore why SIP interoperability seems to be as challenging as it appears, how the vendors are dealing with it and solutions you can use to solve difficult interoperability challenges.

The Root Cause
Let's start with a discussion on the root causes that make SIP interoperability difficult. The problem starts not with technology, but with the way that IETF Requests For Comments (RFCs) are developed. As opposed to the old ITU specifications that the Telecommunications Industry has lived with for the last four decades, IETF RFCs and Drafts are developed in an open and communal environment, using committees and consensus to craft the specification. This has very many positive benefits, but also a few predictable negative side effects. The problem is that RFC 3261 that defines SIP has become "everything to everyone" and bloated in both size and in flexibility.

Performing a simple word count on RFC 3261 yields some interesting insight into the problem:

Weak Terms
Can = 475
Option = 144
Should = 344
May = 381
 

Strong Terms
Shall = 4
Must = 631

As you can see, the number of weak terms "May," "Should," "Option" and "Can" outnumber the stronger "Shall" and "Must," which results in a very loose specification that allows the developers of SIP-based systems to make plenty of decisions on features of functions. The byproduct of this is that two systems can be completely RFC 3261 compliant and completely incompatible.

Examples
In our experience, there are no fewer than five "correct" ways to transport DTMF tones from one end point to another:

  • In-band--leaves the DTMF tones in the RTP streams 
  • RFC 2833--uses specialized payload packets in the RTP stream to indicate a DTMF tone 
  • SIP NOTIFY--uses a SIP message to indicate the presence of a DTMF key press 
  • SIP INFO (Nortel)--a technique frequently used in Nortel systems that uses a SIP INFO message 
  • SIP INFO (Cisco)--a variation on the above, but with some slight modifications.

Another example that is causing a lot of grief right now whether to transport the SIP messages over UDP or TCP. The RFC indicates that either is okay and recommends supporting both, but few manufacturers actually do support both. The vast majority of equipment and application developers chose SIP-over-UDP. Microsoft chose SIP-over-TCP. Again, both are within specification and completely incompatible.

And this my friends is only the tip of the iceberg.

While these technical challenges may seem difficult to overcome, they can be solved. However, the political issues are another story. I'll discuss these in the next post.

Branch offices are the life blood for a wide range of businesses. Financial service companies, insurance, retail, education and government vertical markets depend heavily on having a physical presence in the neighborhood of their customers. However, having a physical office means you need a reliable means to communicate with both customers serviced by the office and the employees in the branch office. To date, most branch offices have low-cost stand-alone TDM telephone systems (aka Key Systems) and use the expensive legacy PSTN to make and receive telephone calls between offices and to their customers.
 
Meanwhile, most businesses today also have some form of IP connectivity for each branch office, whether a private MPLS network or use of the public internet. The IP services are needed for inventory systems, point of sale or email/web.
 
This situation leads to an opportunity to combine the two networks, leveraging VoIP and SIP to network the branch offices together and reduce operational costs. 
 
Potential areas of savings:
  • Reduction of trunk lines to branch offices
  • Elimination of toll charges for inter-office calling
  • Consolidation of trunking facilities
  • Centralized applications (voice mail, IVR and ACD systems)
  • Easier remote management and elimination of "truck rolls"
  • Improved productivity with Unified Communications capabilities
 
With all these areas of potential savings, it should be easy to justify migration to an all SIP-based architecture for branch offices, but there are a few barriers that need to be resolved:
  • Survivability - what happens at the branch if the wide-area network goes down or accidentally cut? An extreme example of this is the outage in San Jose, CA on April 8th, 2009 where a major fiber optic line was cut by vandals.
  • Local Numbers - will you still have the same local numbers that long-established customers have on their prescription bottles or refrigerator magnets?
  • E911 - if there is an emergency, will the first responders be directed to the right facility?
  • Broadband Availability? - while quite common in urban and suburban areas, wireline broadband is either very difficult to get or very expensive in most of rural America. Common wireless technologies including EVDO, WiMax and satellite are not conducive to voice traffic and may insert significant latency or jitter.
 
The challenge is to find an architecture that balances the cost savings of SIP-based branch office communications with the needs for reliability and maintaining local access.
 
Slide1.PNG
A Fully Distributed architecture with separate stand-alone equipment at each site pushes all the intelligence to the branch offices, but doesn't consolidate resources or save enough money to make it viable over the long haul. Many of the smaller IP-PBX or communications appliance vendors are touting this architecture, mostly because customers are used to this from the key system days.
 
Slide2.PNG
A Fully Centralized architecture moves all the intelligence to the core with a large IP-PBX or Softswitch at the headquarters or hosting site and just network equipment and IP phones at the branches. This architecture dramatically reduces costs of the equipment at the branches, but is highly dependent on the quality and stability of the WAN. Local number portability and E911 questions create other problems.
 
Slide3.PNG
It seems that a hybrid architecture that combines the the best attributes of the fully distributed and fully centralized is much more realistic and is becoming the reference for most network designs going forward. This architecture puts some intelligence at the branch offices, which could include either a small IP-PBX or SIP Proxy to handle intra-office calls or emergency calling. The large centralized IP-PBX or Softswitch would manage inter-office traffic. Other application components including voice mail, local IVR and ACD at the branch offices off-load these services from the central site and allow them to operate with less expensive WAN services or in cases of a WAN failure.
 
Slide4.png
Where the dramatic cost savings of this architecture comes to fruition is when the data connectivity, routing, security and application features come together in a single appliance at the branch. A number of solution vendors (including AudioCodes) are starting to leverage Multi-Service Business Gateway (MSBG) devices to host a small version of their application, a SIP proxy or other intelligence for the branch office along with the data connectivity infrastructure. MSBGs are ideal for "greenfield" branch office deployments where new offices or complete network renovations are in process.  Benefits to the enterprise include a dramatic simplification of installation and maintenance across a large number of remote sites.
 
So, getting back to the original question: "Can branch offices save money and be survivable?" The answer is "yes", consolidating voice and data traffic on to one network and reducing maintenance costs for older equipment can definitely reduce operating costs. However, it takes careful planning to choose an architecture and appropriate equipment that fits the particular enterprise's needs for survivability and cost savings. A pharmacy is a very different business from convenience stores. Since you know your business better than anyone, choosing the right balance between the centralized and distributed architectures is something that only you can decide upon.

First I'm going to assume that you know that SIP trunking is a replacement for legacy TDM trunking lines that connect various size enterprises to the public network.  SIP trunks offer similar services, but instead of using dedicated TDM T1/E1 or analog telephone lines, the voice traffic is transported over IP-based data circuits.  SIP is used as the signaling protocol, controlling the start and stop of each voice conversation, associated caller ID and other enhanced services.

SIP trunks are not all created equal though - there are some very significant differences in the way they are sold and the services they support. I could spend months going into all the various technical and business model differences between the vendors, but today I'm just going to concentrate on the different ways they are delivered to the customer.

Tightly Bundled SIP Trunks
These typically are tightly tied to data services that would come from the service provider.  In this case, the service provider requires that you use their data infrastructure to carry the SIP trunks. They arrange for the last mile circuit, provide all the equipment and provide the services with one bill. The logic the service provider uses for this offering is that unless they can control the data infrastructure end-to-end, they can't guarantee the voice quality.  The biggest benefit of the bundled services is that it gives the customer "one throat to choke" if there are issues with the service or quality of calls.  

However, I've heard some push-back from customers on this "take it or leave it" business model, requiring that they buy both the broadband and voice services together.  In some cases the cost reduction doesn't justify the complexity and risk.  What if the enterprise already has an established relationship with a broadband provider and is under contract?  Do they need to pay to break the contract?  What about the risk of potential disruption while migrating both the voice and data services to a new service provider?  Can the service provider deliver both voice and data services to all my offices?

In the end, it seems tightly bundled SIP trunks are best suited to greenfield deployments within the service provider's area of coverage.

BYOBB SIP Trunks
The opposite of the above separates the SIP trunks from the broadband delivery to the customers site.  In this case, SIP trunks are a service that the customer uses on their existing or upgraded broadband facilities.  Thus the term Bring Your Own BroadBand (or BYOBB) was born.

The advantages of this service offering is that it can be offered virtually everywhere where there is sufficient broadband and it can be layered on top of existing Internet services. This allows an enterprise to partially or fully migrate to SIP trunking without disrupting their current data services.  For some enterprises, they have already done extensive upgrades to their data infrastructure and SIP trunking is just another application that was already budgeted for well in advance.  The ability to choose multiple SIP trunking services separately from the broadband is a powerful tool when negotiating on a service contract, especially when looking for local numbers outside the US.

Many of the BYOBB SIP trunking service providers let you choose the equipment at your premise.  From WAN access, the router, security solution and the media gateway.

On the downside, I've heard some debate about the validity of the methods used to test the existing broadband circuits and how to prove compliance with service level agreement terms, especially with voice quality.  Then there is a long-term problem of the broadband carrier managing the traffic inside their network.   If it works today, will it work tomorrow as they add new customers? It's important to choose a service provider that supports built-in quality monitoring capabilities, including RTCP-XR which reports real-time R factor scores on voice quality.

Can You Have your Cake and Eat it too?
There are a number SIP trunking service providers that try to ride the fence and will offer you either a bundled service or unbundled, based on your individual situation.  However, it sounds like you will get pressured hard to take the bundled service to control quality and "maximize value".  The bundled services are frequently wrapped up in one-size-fits-all packages that are a lot easier for them to sell, install and service.  The only question is:  Do you fit the one size they are offering?

What's Right for You?
Well, it really depends on a few factors:
  1. How much do you value having "one throat to choke"?
  2. How much bandwidth do you currently have and is it voice-ready?  If you already have a good broadband provider, use it!  If not, maybe a bundle would get both upgraded at once for a good price.
  3. Are you under contract with either a voice or data service provider?  Does it make sense to break either or both the contracts?  Work the numbers - then decide.
  4. How much control do you want over the equipment and services?  If you could care less, just go with a bundle.  The more you know, the more control over the services and equipment you will invariably want - go with unbundled services.
  5. Are you planning a slow migration with a few circuits to start or are you going to cut over all at once?  Complex and gradual cut-overs need more control.
Hopefully this background on the range of SIP trunking offerings will help you with your adoption.  Make sure you ask the right questions and consider your individual situation before signing anything!

It turns out it's not that easy.  From listening to our partners and their customers, I have learned there are a few real challenges they deal with when deploying communications systems into distributed branch office situations:

First you need to get good quality broadband to every one of your branch offices, which is hard to do once you leave the urban/suburban rings of most cities.  Getting voice-grade  broadband to remote offices in rural America can be very expensive and wipe out any potential cost savings.  Consumer grade broadband is easier to get, but even then not predictable enough for commercial applications.

Second is the question of reliability, which was recently demonstrated by the massive Internet outage in San Jose. What will happen to your business if the broadband connection to the site is cut?  Do you just close for the day and kiss off the revenue?

Third is network traffic optimization - does every call really need tie up your broadband service?  Is there a more efficient way to leverage the expensive and shared broadband that services the branch offices?

The solutions seems to be in an architecture that fits somewhere between the two extremes of fully centralized and fully distributed, but exactly where depends on the individual business.

To discuss these challenges and some potential solutions, I've invited Bruce Mazza, Director of Branch Office Solutions for Avaya to join me in a live webinar on Tuesday, April 14th at 2 PM.  I encourage you to Click here to register for the live event or listen to an on-demand recording of the event.]]> Tags: , ,

As Kevin Kennedy, president and CEO, Avaya noted in both his keynote address and press materials:  "We've seen some organizations use SIP routing to reduce trunking costs by 20 percent to 60 percent. With this new architecture, for the first time, the way we communicate is defined by the applications and the user, not the network."

VoiceCon 2009 006A.jpgBruce Mazza, Director of Branch Office Solutions and Alon Waks, Solutions and Product Marketing for Avaya gave me a quick tour and demo of the Remote Branch portion of the solution showing how branch offices leverage  AudioCodes MediaPack analog gateways to provide survivability in situations where the wide-area-network were to fail or become unavailable.

In addition to survivability, the AudioCodes MediaPack gateways can provide connectivity to analog phones, fax machines and other legacy devices in remote branches.

This announcement highlights one of my key strategic visions of the power of SIP, connecting diverse and distributed businesses together at far lower costs than using the PSTN to call inter-branch.  

I'll be joined by Bruce Mazza to discuss the new Avaya Aura strategy and branch office survivability in an upcoming webinar that I'll be hosting.  Click here to register for the event. ]]> Tags: , , , ,

Bruce Mazza (crop).JPGAP: Bruce, thanks again for joining us in Orlando. What's the title/topic of your presentation?

BM:  "Distributed Enterprises -Reduce Operating Costs and Maintain Reliability"
 
AP: How does the Avaya application help enterprises in this difficult economy?    

BM: The joint solution from Avaya and AudioCodes will help medium and large businesses with many small branch office locations to reduce the cost of deploying and managing communications by centralizing trunking access and reducing monthly fees, reducing inter-enterprise long-distance fees by running voice over the customers WAN, centralizing management to reduce overhead costs, all while increasing branch user productivity through value-added UC applications.   Since the solution is survivable with the AudioCodes SAS capability matched with Avaya's SIP 96xx phones, branch office users can have the assurance of business continuity.
 
AP: What will this solution mean to VARs that service companies with remote branches?  

BM:  VARs will enjoy the opportunity to address medium and large enterprises with a full complement of branch solutions from Avaya, and to address the very small branches that are so prevalent with the survivable SIP branch solution from AudioCodes and Avaya.  Opportunities exist for product sales in Data Centers, and Branches, as well as services to design, build, and deploy customers branch networks.
 
AP: What about the Avaya strategy is different from before the economy went sour?   

BM: Frankly, we had planned to introduce this solution before the economy went sour. Now customers will be even more compelled to implement the solution to gain the OPEX savings.
 
AP: Share with us who would get the most out of your presentation at VoiceCon?    

BM: I believe IT Manager, Telecom Directors and CIOs of companies that numerous remote branches would find the session very helpful. 
 
 
AP :Where would someone learn more about the Avaya Branch Office solution?    

BM: We'll have information at both the Avaya and AudioCodes booths with live demonstrations that can be seen by attendees.

Bruce's presentation is scheduled for Tuesday, March 31st at 2:00 PM EDT in the AudioCodes / ScanSource Solutions Theater within booth #931.

Did I mention that by attending you can win one of 14 iPod Touch PM3 players that we are giving away?

AP: Can you share with us the title and topic of your presentation?

JM: Sure, the title is 'SIP Trunking - Ready for Prime Time '

AP: How does SIP Trunking help enterprises in this difficult economy?

JM: SIP trunking has two immediate benefits for enterprises, especially in light of economic conditions. The first is the ability to broaden an enterprise's reach via the use of remote local telephone numbers. For example, an enterprise that is forced to consolidate and close down physical locations can retain those telephone numbers and have them ring into one or more centralized facilities. In this way, local identification is retained, operations are consolidated, and costs can be dramatically reduced. In addition, new locations can be opened throughout North America and internationally with those calls received by an enterprise call center. The second benefit is the ability to reduce reliance on dedicated telephone circuits for voice and reduce the cost of incoming and outgoing telephone calls. This includes both domestic and international. Our research indicates that savings of 25% to 70% of the annual telecommunications budget is achievable. In difficult economic times, those savings go directly to the bottom line and can be reused to the benefit of the business.

AP: How will value added resellers (VARs) benefit from reselling SIP Trunking from BandTel?

JM: BandTel offers a percentage of monthly recurring revenues brought to us for the life of the service. As long as the customer remains with BandTel, our partners will receive the benefit of their efforts.

AP: What about the BandTel strategy is different from before the economy went sour?

JM: Our strategy has not changed. We believe that businesses want to do more for their operating expenditures, and to find new ways of serving their markets. What has changed is the mindset of our customers. They are no longer content to pay high prices to traditional communications carriers without considering new and different ways to accomplish the same results for less money.

AP: Who would get the most out of attending your presentation?

JM: Anyone who is responsible for finding ways to lower communications costs without sacrificing value will find the presentation valuable. This includes information technology and telecommunications staff organizations, financial personnel responsible for scrutinizing budgets, and value-added resellers seeking an additional profit center to the benefit of their customers and clients.


AP: Where would someone learn more about your solution?

JM: BandTel's website - www.bandtel.com - offers a wealth of information including white papers, FAQs, and case studies.

Joel's presentation is scheduled in the AudioCodes / ScanSource Solutions Theater in Booth #931 at 4:00 PM EDT on Monday, March 30th.  ]]> Tags: , , , , ,
