Hello Alexey,
Thank you on reply,
I undone all changes regard headers
changes and MS Teams send BYE directly to asterisk.
No Route header present.
But INVITE ACK 183 180 all travel withÂ
proper routing information.

Hi volga629, There were nothing special for ACK. You don't need to change To/From/Contact. All the necessary steps were in the article https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/ and for most people it still works. So I'm not sure, that MS changed anything, because all the hardware SBCs should change behaviour, so they need new firmware. SBC vendors should inform customers to update etc. So this is not so simple process. And it definitely make no sense for anybody. And in the test lab for the article I've used absolutely the same architecture with asterisk, the only difference was RTPEngine to transcode SRTP-RTP. And within test lab I've tested not only calls, but transfers worked fine too.----- --- Alexey Vasilyev -- Sent from: http://opensips-open-sip-server.1449251.n2.nabble.com/OpenSIPS-Users-f1449235.html _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
