VoWiFi Will Play a Critical Role in Extending Voice Coverage

June 30, 2015

Voice over WiFi (VoWiFi)...what’s the big deal?  For instance, I can already engage in VoWiFi with some VoIP clients that are downloaded to my phone. The difference is that the subscriber, who may still be actually using the carrier data network, is now from a certain perspective not using the carrier network because the individual is now interacting with some kind of over-the-top content (OTT) app. 

From a carrier perspective, that’s not really acceptable as they are losing the main interface to the subscriber and becoming just a dumb pipe, which most of them don’t want to do since they’d lose significant ability to obtain additional revenue from the offering of value added services.

It's VoLTE Time

June 23, 2015



It’s Voice over LTE (VoLTE time). As we all know, the numbers of LTE networks and subscribers have been growing tremendously; the former, for instance, is expected to reach 460 by the end of 2015. And we’ve all enjoyed getting data via a more landline-like experience thanks to rapid LTE network connectivity.

From a voice perspective, however, VoLTE is still in its early developmental phases.



Video and Voice over LTE/ WiFi Requires a Media Server

June 16, 2015

With the LTE World Summit coming up next week, there will be much discussion about voice and video over LTE as well as voice and video over WiFi. I’ll be writing some blogs about those topics in the weeks to come.

There is no doubt that voice and video over LTE and WiFi is increasingly emerging; however, it’s  important to remember that the world is not still just a bubble of LTE networks. That is, if you want to place a call from an LTE network to a 3G network, signaling conversion must still take place (see my last blog for more on this). 

The Importance of 3G Interworking with Diameter and RADIUS

June 9, 2015


The number of LTE networks is expected to be 460 by the end of 2015, supporting approximately 500 million subscribers at the end of 2014, according to data from GSMA Intelligence. There is continued phenomenal growth in sight, but that doesn’t mean 3G should be forgotten. In fact, it’s quite the opposite; 3G connections will continue to grow at least through 2020 where the forecasting ends, also according to GSMA. It’s likely to continue growing beyond that, too.


Dialogic Worldwide Road trip and Why Software and NFV Aren't the Same Thing

June 2, 2015

Dialogic kicked off a worldwide roadtrip for our customers and prospects focused on meeting the needs of the service provider community. With a packed agenda and room in Tel Aviv last week we got off to a good start. Key items discussed were VoLTE and VoWiFi, Telco Apps, NGN Transformation, Signaling Interworking, WebRTC and Network Functions Virtualization (NFV).
