SIP: Looking Behind the Curtain

Are you coming to Enterprise Connect in March?  If so, here are a few reasons why you want/need to attend my ever-popular SIP session. SIP:  Looking Behind the Curtain

SBC ABCs…and Then Some

And now for something completely different.  I recently sat down with Beth Schultz to talk SBCs for the No Jitter On Air series of Podcasts.  We start with the “motherhood and apple pie” of SBCs before looking at how they are evolving and where they might be in a few years. SBC ABCs…and Then Some […]

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 […]

SIP Architecture 101

Enterprise Connect is a little more than a month away and I am in the process of putting the final touches on my Understanding and Leveraging SIP for your Enterprise presentation. With me, it’s always a balancing act between down-in-the-weeds protocol geekiness and enterprise solutions. While I admit to favoring the former, I realize that […]

SIP Survivability vs. Mother Nature

One of the biggest aspects of my job is helping enterprises transition from TDM to SIP. For the most part, this entails analyzing call volumes, identifying and quantifying risk, qualifying SIP servers and services, and creating a resilient, redundant SIP architecture with no single points of failure. Nine times out of ten this is driven […]

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 […]

The VPN is Dead…

My job used to be a place I went to.  If my car broke down, I didn’t work.   If the roads were too icy to drive on, I didn’t work.  If I had to stay home waiting for a repair person, I didn’t work.  I suppose I could have sat down with a pad of […]
