Guys, Hold/Unhold, blind transfers is fine without REFER support But... Please note that attended (consult) transfer will not work. I did many tests and MS does 3th call to connect Transferee and Transfer Target. Not sure why. I tried same things from regular softphone - and it works great without 3th call.

And based on my research and testing right now is not possible with opensips. MS Teams are sending on hold in case of transfer and onhold as a=inactive. Major problem they require encode/decode params in REFER-TO REFER-BY. MS Teams expect observe REFER with 202 and decode params with future action. Here official requirements doc. https://docs.microsoft.com/en-us/microsoftteams/direct-routing-protocols-sip#call-transfer Any suggestion welcome. volga629. _______________________________________________ Users mailing list Users@lists.opensips.org<mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users _______________________________________________ Users mailing list Users@lists.opensips.org<mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users _______________________________________________ Users mailing list Users@lists.opensips.org<mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users
