What does having no PSTN lines really mean?

by Jim Machi

Mar 21, 2017 10:10:03 AM

There are firm actions starting to take place about PSTN (public switch telephone network) 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.  And they are likely years away, even for the closest ones.  But this PSTN sunset has caused much trepidation anyway. Because, what does having no PSTN lines really mean?

The Importance of Good Call Progress Analysis with Software Media Servers

by Jim Machi

Mar 14, 2017 10:30:44 AM

 

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.

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

by Jim Machi

Mar 7, 2017 9:51:13 AM

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.   But just because Robo-calls are bad, it doesn’t mean that the technology that allows those kinds of calls are bad.  Call Progress Analysis (CPA) is one of those technologies, and CPA is but one of many technologies that enable the bad apple Robo-Calls to happen.

How Service Providers Can Avoid Becoming A Bit-Pipe

by Jim Machi

Feb 21, 2017 2:34:55 PM

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

What to Expect at MWC 2017

by Jim Machi

Feb 14, 2017 11:35:27 AM

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

OTT and the Enterprise and the Impact on Service Providers

by Jim Machi

Feb 7, 2017 9:42:34 AM

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.

Benefits of a Hybrid SFU-MCU WebRTC Architecture

by Jim Machi

Jan 31, 2017 9:44:04 AM

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.

WebRTC SFU Architecture = Champion of Large Scale Video Conferences

by Jim Machi

Jan 24, 2017 10:03:36 AM

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.

WebRTC MCU Architecture - All For One And One For All

by Jim Machi

Jan 17, 2017 10:01:07 AM

The conferencing market is huge. It was expected to be over $2B in size in 2016.  And with good reason – it fulfills a business need to talk to, and interact with each other through voice and video and various collaboration techniques such as whiteboarding.  But we’ve all been on large conference calls at work where people are added and then you can very visibly tell that the performance had degraded.  And then we’re all in for a bad experience.  Many times this has to do with a slow connection – one bad apple ruining the rest.  But this can also have something to do either with the underlying media server being used, or with the conference call architecture being used. Either way, this is avoidable.
