Death and SIP Taxes

The wages of sin are death, but by the time taxes are taken out, it’s just sort of a tired feeling. — Paula Poundstone There are very few things in life that I truly hate.  Yes, there is much that I very much dislike, but hate is such a strong word that I like to […]

With SBCs, Little Things Matter

I try to do the right thing at the right time. They may just be little things, but usually they make the difference between winning and losing. — Kareem Abdul-Jabbar I’ve been married a long time, and if I’ve learned one big lesson these past 34+ years, it’s pay attention to the little things.  For […]

Where Have all the SBCs Gone

A few weeks ago, I wrote the first of my teaser articles for the Enterprise Connect 2016 session, Understanding and Leveraging SIP for Your Enterprise. Admittedly, it was pretty nerdy and protocol intensive, and while I will certainly be delving into the low level aspects of SIP during my EC16 presentation, I plan on doing […]

High Availability Session Border Controllers Down and Dirty

Any subject worth learning is like an onion. No, not because it will make you cry (although some sure bring out the tears for me). Rather, it’s because a worthwhile subject consists of multiple layers and every time you think you completely understand the whole thing, you find something new to capture your time and […]

Peeling Back the SIP Resiliency Layers

Like most people, I like it when my machines work. If I get into my car and turn the key, I expect the engine to start and the tires to roll. Of course, I play an important role in keeping my Prius on the road. I follow the manufacturer’s recommended maintenance schedule. I keep the […]

SIP has been around since the late 1990’s, but confusion still exists about what it exactly is and what it can do. Most telephony people understand that SIP changes the way we make voice and video calls, but their understanding is often sketchy. The confusion surrounding SIP is often greatest when it comes to the […]

SIP Security at Converge2015

When you think about security in terms of SIP and VoIP, you need to consider four different areas.  First, you want to protect the SIP signaling.  Second, you need to protect the media stream.  Third, you need to ensure that people are who they say they are.  Lastly, you need to create a secure network […]

The Fine Art of Choosing the Right SBC

I wear many different hats during the day, but the one that pays most of the bills is that of “The SIP Guy.” While I can’t take credit for coming up with SIP (that honor goes to Henning Schulzrinne and Mark Handley), I did start working with it early on and co-developed a SIP stack […]

A Necessary Guide to the Avaya traceSBC Utility

A few months ago, I wrote what has become the most popular guide for the Avaya Session Manager SIP tracing tool, traceSM. Of course, it doesn’t hurt that I may have written the only guide, but I will take recognition in any way that I can. Today, I hope to do the same for the […]

Striking the Right WebRTC Balance

I stir up controversy every time I say this, but I will say it anyway. WebRTC does not define a signaling protocol. This means that developers are free to use whatever method or protocol they want when they create their solutions. In my latest article for No Jitter, I introduce my readers to the AudioCodes […]
