What does having no PSTN lines really mean?

March 21, 2017

There are firm actions starting to take place about PSTN sunset.  What this means is that our landline networks that we grew up with will cease to exist – they are too costly to continue to support.  Effectively, the VoIP movement that started in the mid 1990s will have “won.”  And what a swift victory that has been.

Countries will have various PSTN sunset dates. 

The Importance of Good Call Progress Analysis with Software Media Servers

March 14, 2017


Robo-Calls are rightly getting negative press and regulation. But Call Progress Analysis (CPA) has many legitimate uses beyond enabling Robo-Calls. Dialogic has been getting quite a few questions lately about software based CPA because of the legitimate uses as discussed last week.

CPA was first enabled via sophisticated algorithms that first started being employed via DSPs. But as hardware such as call processing boards have morphed into software modules, the CPA algorithms might not be quite the same.Host processing, say using Intel CPUs, may not be as powerful.

Call Progress Analysis is Not the same as a Robo-Call

March 7, 2017

Robo-calls are making the news lately.  I even wrote a blog about them last year. We all hate getting those calls. While most contact centers follow the rules, there are companies that don’t and they are the ones that cause consumer frustration. 

What's Going on at MWC 2017

February 28, 2017

I’ve been at Mobile World Congress one day so far.  5G is everywhere and around every corner and under every rock.  Can’t get away from it.

It’s also clear that I was right about seeing IoT and Cloud messaging everywhere.

How Service Providers Can Avoid Becoming A Bit-Pipe

February 21, 2017

I was recently talking to STL Partners / Telco 2.0 and we had a discussion about service providers now facing the similar disruption from over-the-top (OTT) players in enterprise communications as they saw with consumers. It’s an interesting issue. The “bring your own” app phenomenon has started, and enterprises are starting to see their  employees bringing WhatsApp and WeChat to the office to use for work, similar to how I brought non-enterprise Skype to the office to use.  WhatsApp has even announced business integration plans.

What to Expect at MWC 2017

February 14, 2017



Mobile World Congress is coming up soon and it’s always fun to speculate on industry marketing trends one might expect to see.  First of all, with a generally poor 2016 for telecom infrastructure vendors, which comprise the bulk of the companies with MWC booths, we’ll probably see an overall muting of far out expensive “come look here” marketing and parties. I do expect to see three main trends, though:

  1. IoT messaging will be everywhere.  I might even see drones flying around with little marketing banners, though I doubt the GSMA would allow that. 

OTT and the Enterprise and the Impact on Service Providers

February 7, 2017



Service Providers don’t just provide services to consumer subscribers like you and me.  Service providers also provide a lot of services to enterprises. And the revenue derived from these services, such as text messaging, other messaging, and voice services, has declined as data usage has soared, the same trend they saw with consumer subscribers.  With data usage comes data apps that provide these services for “free” (though the subscribers are paying for the data usage).

Benefits of a Hybrid SFU-MCU WebRTC Architecture

January 31, 2017


Multipoint control unit architectures are ideal for when compute and bandwidth are limited and there is a need for interoperability with disparate networks, but come at a cost of high server load and limiting video layout. On the other hand, selective forwarding unit topologies are ideal for high server performance and maximum flexibility for the client UI but come at a cost of requiring all connecting clients to share the same codec, frame-rate,

A hybrid-SFU/MCU topology allows for the media stream to be delivered based on the preference optimized for the individual client.  For example, in cases where the client is a mobile or SIP device the media server can deliver a single MCU-type mixed stream.

WebRTC SFU Architecture = Champion of Large Scale Video Conferences

January 24, 2017


Whether it’s one bad connection degrading the quality of the entire conference, or problems with the underlying media server or conference call architecture, a poor conferencing experience is avoidable. For large scale video conferences, the Selective Forwarding Unit (SFU) architecture may be a good way to go.

SFU is a topology allowing for clients to send their encoded video stream to the centralized media server where it is then forwarded/routed to the other clients. The SFU topology is an attractive approach to addressing the server performance issue, as it doesn’t involve the compute expense of video decoding and encoding.
