A Look at How Avaya Aura Supports SIP-Based Voice Mail

I believe I have been pretty clear about this. I am not a fan of voice mail. I don’t like leaving them because I know that most will never be heard and I don’t like listening to them because text and email are quicker and more efficient. Needless to say, I was thrilled when I […]

Why 2014 Was a Good Year

We all know the story of the glass of water. The optimist will tell you that it’s half full while the pessimist declares it half empty. Well, I am here to tell you that there is a third option. The glass contains exactly the right amount–not too much and not too little. As 2014 comes […]

A Wireshark View of Real-Time Control Protocol (RTCP)

I’ve been on a Wireshark binge these past few weeks.

Two weeks ago, I had a little fun by tearing apart a SIP conference call. I was shocked by how popular the article turned out to be. Not only was the view count very respectable, but I received a number of emails from folks who wanted to take it a bit deeper. Seriously, I had […]

Privacy, Online Access, and the Fragility of Life

My latest article for No Jitter is more of a philosophical pondering than a technical exploration (but it’s that, too).  No matter what, it’s something we all deal with every time we open a web page or post a social media status update. Privacy, Online Access, and the Fragility of Life Don’t worry about me […]
