SIP

MetaSwitch, Cisco and Juniper Gossip

September 26, 2006

I spoke at a seminar hosted by Interactive Intelligence like I have been doing more and more lately. Today I was in Detroit, MI, a city and state I have never been to. I was a huge fan of Ford and GM cars in my teens and at that time I had a good friend who used to be from this area. I used to hear lots of great stories about this city and the great cars that were created here.

Of course we have all been hearing stories about the turmoil at Ford, GM and Chrysler as of late and I knew the economy here isn't great.

IVR Technologies

September 26, 2006

I met up with Barry Sher last week and hadn't spoken to him in a while. He used to work for Telephony Experts back in the good old days of the nineties when Computer Telephony and CTI were all the rage.

Barry now works for a company called IVR Technologies and we had a chance to go over what is exciting in the world of telecom and SIP.

His company develops SIP applications and one of their products is called Talking SIP which is a Software only service that calls anywhere -- any time via SIP. As Barry describes it, customers bolt up to Level3 or Teleglobe and they peer via sip.

Talking SIP is a real-time media server, billing server and application server in one box. One application it can handle is prepaid calling cards or a reminder service that performs wake up calls.

Talking SIP performs real-time call processing via SIP messaging and provides independent, script-controlled IVR prompting over RTP.

Consider a typical tax return. If you own a home and have a mortgage you may be able to deduct interest payments -- at least in the US (oh and by the way this article is not meant to provide you with advice on doing your taxes. Please don't expect it to help you with the IRS at your next audit). If you made interest you must pay tax on it and of course on other income.

Rodopi Software

Recently I had a chance to travel to Southern California and see the many companies that make up the IP communications market of the state. Two things I noticed about Southern California are the food is still great out there and the traffic problem isn't getting any better. Thankfully the carpool lane was available and this made traveling much more effective.

In all my trips to California I never driven on a toll road and I found these highways to be great ways to minimize traffic. What I didn't realize is some of these roads require you to have exact change and unlike every other toll I have ever seen in my life, if you don't have exact change you are left without many options.

Bandtel

Out of the many areas in the IP communications space worth watching, I think SIP trunking (see TMCnet's SIP Week in Review for lots more info on the SIP trunking market) is among the more interesting. I say this because for as long as PBXs have been around so have hardware-based PBX interfaces.

SIP has changed this (subscribe free to SIP Magazine to learn more) and now telephony has a lot less proprietary hardware and a lot more flexibility. Ironically as so many IP-based call centers and IP-PBXs are being sold worldwide, they aren't all connecting to SIP trunks -- they still use the PSTN. By some accounts less than half of IP PBXs are connected to SIP trunks.

So the benefits of putting voice over IP are only partially taken advantage of.



PASATA

September 19, 2006

Depending on what research you subscribe to you will hear that 40-60% of all calls either end up in or are checking voicemail. Now I am no expert on productivity and how it correlates to GDP and work output but it seems to me that even shaving a percent off the above numbers is a major improvement.

Certainly I am a big believer in a world of presence enabled applications and technologies and devices. This is one of the reasons my company launched SIP magazine in fact. I know in the future we will have intelligent networks that will know where we are and what we are doing and these agents will be able to forward our calls to the correct phone depending on where we are, what our presence information is and who is calling.

So I am happy that IBM has teamed up with Telenor to develop Presence Advanced Services for Telco Applications or "PASATA."

The technology holds great promise not only because of its applications in the enterprise, but also because it can streamline call routing efficiency for wireless networks, thus easing network congestion.





Lower Broadband Customer Service Costs

September 19, 2006

Sorry for the self-promotion here but I haven't had a chance to share this with you --the news of a webinar teaching service providers how to lower the costs of broadband customer service. It takes place tomorrow so feel free to forward I to colleagues now so they don't miss it.

Rolling out new technology to your customers is great but you need to make sure that if you are deploying new triple play services you are aren't taking a bath on support costs.

As the complexity of services increases so does support cost. This webinar will help you lower your costs over time by planning early. Enjoy.

Keeping a Lid on Broadband Customer Service Costs

Date: Sept. 20th (tomorrow)
Time: 11:00am PDT (2:00pm EDT)
Register

===============================================
Customer support costs can balloon quickly when rolling out new broadband services.














V2oIP Quality Alliance

September 15, 2006

The V2oIP Quality Alliance launched this week -- the goal of which is to increase the quality of voice over IP phone calls. Many of the people I spoke with in the organization would prefer the organization be called the Voice, Video Quality Alliance but regardless, that is what the V2oIP acronym stands for and the association's goal is to improve voice  and video quality over IP networks.

You might imagine that today, voice quality has improved so much that we don't need such an organization. But video quality can still improve and this (link fixed) blog entry shows that voice quality may not be as good as you think.

One last point worth considering is that with all the talk of voice peering, we must realize that quality has the potential to get worse. There are a few reasons for this -- increased latency as calls go from one provider to another and transcoding which basically means converting from one codec to another.

Of course when using peering we eliminate the PSTN so we should see gains in voice quality but like everything else over IP -- you need to ensure the network is set up correctly to ensure maximal voice quality.

I think the V2oIP Quality Alliance is a positive step towards improving quality in the IP communications world and as more vendors join the cause I hope we can expect higher quality levels in VoIP and video calls.

This release will give some details on who is participating but suffice it to say there is a smattering of IP communications companies represented from across the industry.

Pretexting – The Good, Bad and Ugly

September 11, 2006

In recent days pretexting has become a mainstream term in newspapers and blogs around the world. Admittedly pretexting is a term that most people are not familiar with and most are shocked when they learn what it is. Pretexting is pretending to be someone else and obtaining personal information about that person under the pretext of being them. What most people don’t realize is how easy it is to get a hold of information like phone records with a person’s phone number and last four digits of their social security number.

The reason pretexting has been in the news so often lately is that Hewlett Packard used this technique to obtain phone records of journalists and board members in an effort to determine the source of leaks of confidential information to the press.

You may recall that Carly Fiorina had dealt with the problems of leaks to the press years ago and obviously things haven’t changed at HP and leaks continue to plague management.

In order to get to the bottom of the leaks HP Chairwoman Patricia Dunn ordered an investigation into the leaks and in doing so hired at least one outside firm to find out who was responsible letting confidential information out.
