Teams Call Transfer No "REFER"

    We have a working setup Teams<->AudioCodes<->SIP,  and recently call transfer out from Teams has stopped working. AC's captured log shows that SBC is not receiving REFER from Teams. Kindly give me the head-up on where we shall be looking at.

    If you do not see even REFER on AC SBC side while trying to transfer call I would dig in into reasons on Teams side and not on SBC. I would check calling rights of the person, might be that he/she tries to transfer to number which is not matching any online voice routing policy pattern, hence to restricted number?

      DaveChomi Appreciate your input. It was working fine and out of a sudden, it stopped working. There weren't any changes to the config. In the end, it was resolved by just rebooting the SBC. :facepalm:

        I have to acknowledge that we had once the similar case in past when SBC just behaved wrongly and after restart it was resolved. Luckily having those in operation already 3 years this happened once so far and only on one HA pair not on the others...knocking on the wood...
