[SR-Users] kamailio integration with MS teams.

[Nasida Yuriy]

Yes, sure, need to fix Record-Route. The question was how exactly :)
Well.  I just fixed it by the way. 200 OK had to have only one record-route (which MS sent in initial invite). Otherwise MS ignore it without any response.

The instructions are pretty clear in the sense that you need to fix
the Record-Route header.
You don't need to touch the Contact header for in-dialog requests/replies.
