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 presenting an abbreviated call flow. There were parts that baffled even me. So, I took it as a personal challenge to figure out the confusing parts as best as I could and put them into writing.
In my latest article for Avaya Connected, I take you on an even deeper journey into the bowels of Avaya Session Manager Call Processing. If you are an Avaya professional that needs to occasionally crank up traceSM and dig through SIP message flows, this article is for you.
