Location-Based Accuracy

September 29, 2015

I’ve written about e911 before, most recently in July where the concept revolved around the role of media servers with e911 and NG911 services. 

I was recently doing some more research on e911 when I came across this interesting paper on the GSA site about location-based services and the accuracy of them.  You’ll need to register to read the entire paper but if you are into math, non-linear equations, and azimuthal alignment of antenna arrays, it will be worth it. 

IMS and VoIP Infrastructure Continue Growth

September 22, 2015

I’ve written from time to time (many times), about how both the IMS, and VoIP infrastructure markets continue to grow.  The IMS market is growing because of LTE.

VoLTE, and VoIP infrastructure markets continue to grow because, even though LTE is growing, everyone has not moved to IMS yet, and want to keep their existing networks going.  In fact, as I’ve written about before, 3G subscribers continue to grow as LTE subscribers also grow. 

Diameter Signaling Controller (DSC) ≠ Diameter Routing Agent (DRA)

September 15, 2015


Many people in our industry confuse a Diameter Signaling Controller (DSC) with a Diameter Routing Agent (DRA). While a DRA was the first and most publicized function of a DSC, and an important one at this, it is not the only function.  With that in mind, Dialogic created a simple “Usages of a Diameter Signaling Controller” Infographic to point out the key uses of a DSC.

Use case 1: DRA

NFV Reality

September 8, 2015



My past two blogs have been about NFV Vendor challenges. From the xSP side, I continue to see what I’ll call extreme interest in our NFV plans.  The xSP’s want to deploy NFV for the reasons the industry has been talking about – CAPEX reduction, OPEX reduction, and New Service Delivery – and they want to deploy it as fast as possible. For instance, AT&T has stated that 5% of its network will be virtualized by the end of this year.

NFV Vendor Challenges Part 2

How will the software in NFV networks interact? Via a Management and Orchestration (MANO) layer.

NFV Vendor Challenges Part 1

August 25, 2015

We’ve all likely seen the Gartner hype cycle for emerging technologies curve.  I remember many, many years ago when I first saw that curve.  I don’t even remember what it was about, but it had the Peak of Inflated Expectations, and then the dip down, and then the path to nirvana.  That curve stays relevant over time because it is so true. 

The Importance of a Software Media Server/Media Resource Broker to Handle Diverse Multimedia Resource Requirements in a VoLTE Network

August 18, 2015


It would be nice sometimes to live in a bubble where you would only have to deal with what was in that bubble. If a Voice over LTE (VoLTE) network existed in a bubble, it would have known multimedia requirements in the form of the codecs and functions specified in the IR.92 and IR.94 voice and video specs. However, a VoLTE network , like us, does not exist in a bubble; that is, we both need to interact with our entire environment. It would be boring if we lived in a bubble anyway!


Exploring the Current Status of WebRTC

August 11, 2015


Last week I was doing some research on WebRTC and I noticed that a lot of the information related to this topic was not from 2015; rather, it was from 2013 or 2014. As a result I couldn’t help but wonder: Does that mean WebRTC is losing its steam, or have we entered a lull in the hype regarding WebRTC? 

My sense is that this lull period is typical of new technologies.


IPX Can Enable Revenue Innovation for Voice Wholesalers--Part II

August 4, 2015


In Part 1 of this series, I wrote about a couple of revenue generating ideas for IPX providers. So how can an IPX provider go about this?  Firstly, the IPX platform needs to be up-to-date as well as support IPX standards. Obviously Dialogic provides an IPX platform or I wouldn’t be writing about this, right?

IPX Can Enable Revenue Innovation for Voice Wholesalers--Part I

July 28, 2015


When I attended International Telecoms Week (ITW) back in May, I wrote about how voice wholesalers are looking to expand their business and innovate. IPX is an enabler for the revenue innovation that these voice wholesalers are looking for. There are a few reasons for this.

First, with IPX there is inclusion with both the various GSMA networks (i.e.
