"How Does Dialogic Fit In with WebRTC?"

May 1, 2013

This blog represents the last of the series of questions we received from attendees of our February 20th WebRTC webinar.  Quite a few of the questions we received during the webinar asked about Dialogic products that could be used to build WebRTC solutions, along with general questions on making the technology work for various use cases.  One solution our customers have found valuable is the  PowerMedia XMS, which is a software media server and IP multimedia system (IMS) media resource function (MRF).  Since WebRTC is poised to dramatically lower the barriers to rich multimedia communication sessions across so many use cases, we believe that WebRTC adoption will drive demand for the scalable, mixed media environment for audio and video.

Why would you want a software based session border controller?

April 30, 2013

Why would you ever want a software-based session border controller (SBC)?  Is it even feasible? Right now, SBC’s are boxes that often implemented at the edges of IP-based networks.  It might seem unlikely for a hardware node of that critical network element morph to become a piece of software.

"The contact center use case looks like a natural for WebRTC, but how will that work?"

April 24, 2013

“The contact center use case looks like a natural for WebRTC, but how will that work?”

From our company’s viewpoint, implementing many of the WebRTC use cases in the modern contact center is a matter of normalizing the media and signaling streams between systems to interface with the existing service. The telco perspective in this context doesn’t mean exclusively carriers or service providers, but a wider view of enabling WebRTC endpoints to access known communication services or solutions, such as a contact center.

While our on-demand webinar described a click-to-call WebRTC use case that may already be emerging in the market, another use case has cropped up that is a practical application in the area of agent login and soft-clients.  

Impact of the New Video Codec H.265

April 23, 2013

In January, a new video codec called H.265 (also known as High Efficiency Video Coding (HEVC) was approved by the ITU-T.  This is significant for a couple of reasons:

It needs only half the bit rate of the best codec out there today (H.264) to provide the same or similar quality video.  You can even see it in this YouTube video.

"Where do IMS and WebRTC Intersect?"

April 17, 2013

The IP Multimedia Subsystem (IMS) is an architectural framework for delivering IP multimedia services. It is based primarily on SIP as a rich, real-time media session protocol for IP networks, and as such, relies on SIP-based endpoints and soft-clients to register and support subscribers on the services (at least those services that are truly multimedia in nature with HD voice and video interactivity, and not ‘skinnied’ down through gateways to a narrowband voice service).

The care and feeding of SIP client applications that enable the IMS service subscribers represents a considerable effort and cost to carriers for their on-net IMS service subscribers. Extending the IMS service reach with soft-clients to off-net endpoints, meaning those that are on other carriers broadband and mobile networks, presents another set of challenges, including various app store navigations and negotiations.

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.
