I have just spent a few days putting together a detailed call flow of jabber with the new collaboration edge feature. Jabber MRA can be complex to implement and there are so many parts to this, so I thought it would be good to have a documentation that attempts to break down the call flow bitsby bit. These will aid in deployment and troubleshooting once the underlying elements are understood.
I have added a few logs excerpts in the documentation to aid in understanding clearly what is going on in each phase of jabber interaction with expressway servers.
Let me know if you have any questions. I have attached the document here as it will be a little difficult to put it here due to the formatting constraints on the portal here.
