WebRTC Webinar Q&A #2 "Why WebRTC when we have Skype?"

April 17, 2013


“Why  WebRTC when we have Skype”?”

This is a really good question.   After all, Skype is the dominant real-time communications technology on the web with hundreds of millions of users and isn’t very hard to use. 


LTE / Diameter Interworking (Part 2 of 2)

April 11, 2013

Two days ago, I wrote a blog about Diameter Interworking use cases.  If you are a network operator, are these issues real? Well, they’re real enough that the 3GPP and GSMA have identified elements called Diameter Routing Agent (DRA),  Diameter Edge Agent (DEA), and Diameter Interworking Function (IWF), which is more closely aligned to the interworking described above.

Given that these issues are real, how do you address them?  For starters, operators need a box that connects the carrier LTE/IMS and policy control environment to existing 2G/3G/Wi-Fi and back office environments.

LTE / Diameter Interworking (Part 1 of 2)

April 9, 2013

Last week, I wrote a blog about Diameter protocol and its application use cases.  Since LTE uses it as a signaling protocol, operators have a need to interwork Diameter with the signaling technologies used in other mobile networks. This has given rise to the Diameter Interworking Gateway function, which moved onto the center stage at Mobile World Congress this year. It’s a critical element to enable the successful rollout of LTE and a seamless user experience across different networks.

WebRTC Webinar Q&A #1 "Is WebRTC 10 years too late?"

April 4, 2013

“Is WebRTC 10 years too late?”

To properly answer this question, one needs to take a position.  One position is to assume that all the VoIP “stuff” that came before Web Real Time Communication (WebRTC) is kind of useless.  But moving to a world where SIP, G.711, and H.264 are the dominant real-time communication protocols and codecs over IP networks is not useless. 

Diameter Use Cases

April 2, 2013

Diameter is the key signaling protocol used in IMS and LTE networks that enable applications running on those networks to authenticate, authorize and charge. In other words, your mobile applications, when running on these networks, are using Diameter protocol in the background to enable you to utilize the many apps on your smartphone or tablet. This includes, for example, a location-based service type of application (such as Foursquare or Yelp), or mobile payment (such as Square), or an Internet purchase (from an app store online retailer like Amazon).

Given the huge amount of smartphones and tablets out there that are either now running on LTE networks are that are expected to be LTE-enabled in the future, I predict that will be a big increase in Diameter signaling traffic.

My Mobile Device History

As some of you readers know, I have been an avid Blackberry user for some time. That time has now past.  I am an equal opportunity device person, and have used Motorola, Nokia and Blackberry devices.  It was time for a new one.


The Contact Center's Continual Transition

March 19, 2013



The contact center is undergoing continual change as companies strive to make their operations more efficient and cost-effective.  This is one of the reasons the contact center has always been an innovator and a driver for new technologies, from VoIP to Web integration to speech recognition.  Now, contact centers are undergoing still further transformation because access to them is coming more and more from smartphones and smartdevices. Contact center operators must look at feasible ways to maximize investments while also integrating modern, media-rich communications that give customers more options.

Mobile Congestion and Radio Blogging and Podcasting

March 12, 2013

Over a month ago, I participated in a radio blog / podcast with Tech in Twenty.  The theme was mobile congestion.  Please listen to the 20 minute broadcast/podcast/radio interview since it was riveting! Seriously, it was fun, the interviewers Luis and Jennifer asked good questions and I think the interview is interesting.
