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 […]

A Close Look at Avaya Aura IMS Call Processing — Part One

It goes without saying that SIP is a protocol. After all, it is Session Initiation Protocol. It’s a series of request methods, responses, headers, and documented call flows. You send an INVITE and expect to receive a 100 Trying, 180 Ringing, and eventually a 200 OK. That’s the way I was taught SIP and that […]

Avaya Aura System Manager Web Services

Ask ten IT professionals what excites them about today’s communication technology and you might hear ten different answers. Some folks get all worked up about video and will bore you to tears with their thoughts on H.264 vs. VP8. Others are more interested in voice and get all warm and fuzzy about quality of service […]

Avaya Aura IMS Processing Once Again

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 worse. I also did myself a favor by presenting […]

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 […]

A Necessary Guide to the Avaya traceSM Utility

Necessity is the mother of invention. Case in point is the Avaya utility, traceSM. As hard as I’ve tried, I have yet to find a halfway decent manual that explains how to use what is perhaps the most important Session Manager debugging tool. I would love to be proved inept in my efforts, but I’ve […]

Understanding SIP Registration

Let’s start at the very beginning a very good place to start when you read you begin with A B C when you sing you begin with Do Re Mi I have always loved musicals and Rogers and Hammerstein’s “The Sound of Music” is high on my list of favorites. Sure, it’s corny and far […]

Implementing Presence With SIP

Are you familiar with busy lamps on telephones? For many years, they were the only way you could “see” the telephone status of a coworker. For example, let’s say that Andrew is the administrative assistant to Debbie and as part of his job, Andrew needs to know when Debbie is on and off the phone. […]

Understanding SIP CANCEL

As I have said on a number of occasions, I occasionally teach a two and half day SIP class. While that’s hardly enough time to become a SIP expert, my students always leave with more than enough knowledge to make educated decisions in regards to SIP endpoints, applications, and trunks. Although some may never again […]
