Debugging Avaya SIP

Another of my Avaya Engage breakout sessions is available for viewing outside the virtual conference.  This time around I explore debugging SIP in an Avaya Aura system.  After a quick introduction to SIP fundamentals, I look at how Avaya Aura uses SIP in an IMS, or half-call model.  I show how resource reservation occurs and […]

Planning a Successful SIP Trunk Migration

I keep getting asked to guest blog post about SIP and I just can’t seem to say “no.”  If you are planning a SIP migration or want to tune your existing configuration, this is the article for you. Planning a Successful SIP Trunk Migration

AudioCodes Tackles Simpler Session Management

As a writer about all things communications, I love the fact that there is always a new subject to explore. Manufacturers are either updating existing products or unveiling something completely new and different. Technology is constantly evolving and change is coming at us at a feverish pitch. On top of that, there are so many […]

Taming the Dial Plan Spaghetti Monster

I have been making and answering telephone calls for over 50 years and yet I still struggle when it comes to remembering the numbers of most of the people I see and work with on a daily basis. Heck, I couldn’t even tell you the telephone numbers of my kid’s cell phones. That’s not because […]

Learning to Work With Avaya Aura Session Manager Adaptations

The problem with standards is that they rarely are. Despite the fact that SIP has been around since the 1990’s, is fairly well documented, and exists inside solutions from a variety of providers, there are still far too many situations where one vendor’s SIP has trouble speaking with another vendor’s SIP. Solution X might use […]

An Even Closer Look at Avaya Aura Call Processing

Last week, I walked you through how Avaya implements IMS processing between Session Manager and Communication Manager.   Even though it may have looked fairly complicated and slightly convoluted, I actually did you a favor by greatly simplifying the call flow. The complete call flow is even more involved. I also did myself a favor by […]

Avaya Session Manager Lessons Learned and Relearned

I attended the International Avaya Users Group Converge2014 in Dallas, Texas last week.  This has been an annual event for me for many years and despite the non-stop days and nearly sleepless nights, it’s something I look forward to very much.  Not only do I get a chance to stand before like-minded people and pontificate […]

The Need for Speed

I never saw the first computer I worked on.  It was 1975 and I was a senior at Coronado High School in Scottsdale, Arizona.  Those of us who took advanced math classes were allowed to sign up for a course in computer programming.   I forget the instructor’s name, but I remember that he only had […]

Session Management

If you have been following my blog it should be clear that I like SIP.  I like it for its simplicity, its ability to create sessions of any media type, and its synergy with the Internet and web.  However, it’s just a protocol and as such it’s basically a bunch of request and response messages.  […]
