Hello Ovidiu,
Thank you for reply
Call flow
Asterisk <-> Opensips <-> MS Teams
Call from MS Teams works 100 % include rtp, but to MS teams no.
I am adding required record routes on INITIAL INVITE, but that not enough based on Johan posted docs.
I accommodated proper rewrite of From/To again based on spec doc in initial request.
All those parts based on debug doc.
Has to be something changed on Microsoft side.

You don't need to mess with the Contact header (unless you are connecting NATed endpoints with MS servers). You need to populate proper Record-Route headers in the initial INVITE as explained int the blog: https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/-ovidiu On Sat, Apr 18, 2020 at 3:26 PM volga629 via Users <[email protected]> wrote:Thank you for reply, I fixed Contact header in ACK, but Microsoft still unhappy call drops after 20 sec.

My guess it expecting FQDN. MS Teams disconnect the call after 20 sec REASON: Q.850;cause=18;text="bc427610-edae-47b9-9daa-7ea74d40dcc7;Call Controller timed out while waiting for acknowledgement." In this case ACK come from asterisk box.
