An SBC is not required for a WebRTC Gateway

March 4, 2014



A session border controller (SBC) is not required for a WebRTC gateway. That might be a strange statement considering most of the industry has assumed an SBC is necessary for successful WebRTC scenarios. Why would the industry make that mistake? Because an SBC is basically an IP-to-IP translation node, and the WebRTC and SIP worlds are both in the IP realm.



The Internet of Things and Other Major Themes from MWC 2014

February 25, 2014

Mobile World Congress is buzzing along. It is a mass of mobile communications humanity, all crisply dressed and swiftly moving along like a flash flood in an Arizona wash through both the Barcelona subway system and the venue at the Fira.

The 2014 Mobile World Congress theme is “Creating What’s Next.” That’s a good theme, but so far, I didn’t see anything unexpected in terms of “next.”

Overall themes I’ve seen on my first day of the event:

The Shazaam! of SS7 - SIP Signaling

February 18, 2014

We’ve been getting a lot of interest in signaling gateways, especially as they relate to SIP. A signaling gateway is similar to a media gateway in that a “conversion” occurs. In the case of a media gateway, there is some kind of voice or video media conversion, usually from one type of codec to another. And typically these involve a signaling conversion in addition to a media conversion.

Diameter, NFV and More Expected at MWC

February 11, 2014

Jim Hodges from Heavy Reading has come out with an interesting report about signaling (Diameter) in next-generation networks. In it, he makes the point that signaling is now front and center in supporting complex service interactions. Diameter signaling controllers (DSC) are rising in importance, and their parts -- including Diameter routing agents (DRA), Diameter edge agents (DEA) and Diameter interworking function (IWF) – are important nodes in the LTE/IMS networks.

Signaling has always supported certain mobile value-added services, and many Dialogic customers purchase both media and signaling from us, creating a litany of value-added service applications. With the faster networks using Diameter, namely LTE networks, we’re bound to see many more interesting applications emerge. 

Mobile Price Wars and Apps - Yes, Apps!

February 4, 2014

There’s been a lot of talk recently in the United States about mobile price wars, such as Quartz’s and Reuters’ reports on T-Mobile’s aggressive move to win over customers from AT&T and Verizon. If the combined voice/data average revenue price per user (ARPU) is dropping everywhere – as it is in Europe according to GSMA Intelligence research, and in the U.S., according to Chetan Sharma Consulting – where will service providers go for new revenue? Clearly a price war is one way to try and win new customers, and thus increase revenue, but it’s not going to increase the ever important ARPU.

What can service providers do?

Mobile and Voice App Update

January 28, 2014

Last week I wrote about chatty apps, which keep contacting the network for continual updates, so users won’t FREAK OUT because they don’t have the absolute latest info.  But what is the status of what is going on with mobile apps anyway?  Is the craze of downloading apps to your smartphone over?  Or do we have all the apps that we need?

Dealing with Chatty Apps

January 21, 2014

When I was at LTE North America, I ran into Monica Paolini of Senza Fili Consulting who had just published a report about chatty apps and mobile signaling.  The report outlines the financial impact of all the signaling from chatty apps because the chatty apps utilize the network and network capacity and could cause congestion. Therefore, the network might not be able to maximize the amount of subscribers, or the network might have to add more infrastructure to handle the traffic.  Either way, there are costs to the carrier.

Billions and Billions of Faxes, Oh My!

January 14, 2014

I haven’t written a blog about fax in two and half years. So why am I writing one now?  I can bet some of the readers of this blog have never even seen a fax machine, since your company probably sends and receives faxes through a multifunction peripheral device (basically a printer and scanner and fax machine all in one). You might chuckle that people well, still fax.

A Winning Use Case for WebRTC in 2014

January 7, 2014

I started off 2013 with a blog about WebRTC. A lot happened with WebRTC in 2013, and the final story is yet to be written, so I’ll also make it the focus of my first blog of 2014. We see WebRTC-enabled media servers playing an important role in the evolution of browser-to-browser communications. If you want to do a WebRTC voice or video conference, you’ll need a WebRTC-enabled media server.
