Small Operators - Are you being left behind?

November 19, 2008

As part of our continuing series on applications based on SIP, I've pulled together Mike Wilkinson of Broadsoft and Scott Firth of IBM to discuss the challenges and solutions that small communications operators can leverage SIP and VoIP to expand their business.   The objective of the event is to educate the smaller and rural telecos, internet service providers, cable companies on the opportunities and solutions available to add voice to their existing IP networks.

The story behind the story starts on my front lawn with the owner of a local fixed wireless ISP we have here in western NY.  His network uses fixed wireless repeaters around northern Allegany County, NY to service hundreds of homes, farms and businesses with broadband that the local ILEC won't service with DSL or other wired broadband technologies.  He was describing his challenges with building out the network and desire to add services to increase revenue.   The rest of the story will be covered in today's event.

Small Operator - Are you being left behind?

Wednesday, November 19, 2008 2:00pm ET / 11:00am PT

Small and mid-tier operators of cable systems, rural telcos, internet service providers, and regional wireless providers are constantly challenged with ways to improve customer retention and increase revenue.

VoIP and other bundled offerings are widely recognized as a means to achieve these goals. Market analyst AMI Partners Inc. agrees, noting in a forecast that SMB hosted VoIP spending will surpass $1.56 billion by 2010. However, the cost, technical complexity and financial risks involved with building a VoIP solution from scratch have been outside the means of many operators and as a result, kept them on the sidelines.

SIP at Astricon

September 24, 2008

I'm here at Astricon in sunny Glendale, AZ with the diverse Asterisk community talking about using SIP to improve the reliability and scalability of Asterisk.  

We had a full room this morning during our session sponsored by both ScanSource and AudioCodes, discussing different architecture tricks to improve reliability of Asterisk solutions and spread out the risk with the goal of avoiding a "career affecting" event.

A quick summary of our recommendations:
  1. Use redundant and commercial grade servers to avoid simple power supply and fan failures from taking out the whole system.  
  2. Use a distributed SIP architecture to separate the Asterisk server, media gateway and phone devices.
  3. Implement a load-balancing scheme to spread the traffic over both Asterisk servers and dual media gateways.
  4. Use Dundi to keep the dual Asterisk servers synchronized and allow them to cover for each other.
  5. ...and many other helpful tips....
We had a number of interesting questions about how Asterisk handles routing the RTP streams around the application server, enabling mid-call fail-over in the case of an Asterisk crash.

VON - End of an era

May 8, 2008


I've been holding my tongue on this topic for since word first got out that PulverMedia had been shut down by it's investors.  I figured that like most rumors, they were only partially true.  In this case, it seems they were true.  The resumes are rolling into our marketing department - confirming what was reported.

Somehow the end of VON has hit me in a way I didn't expect. 

On the road to VON.x and Digium|Asterisk World

VON Week

October 29, 2007

Today marks the first day of VON here in Boston.  As always, I'm looking forward to spending the week listening, learning and sharing about our industry. 

As I spend most of my time working with companies that build enterprise applications, an area I'm planning on paying particular attention to is SIP Trunking
