Teams Direct routing - no BYE message from Teams

Hi,  We have a following problem with Direct Routing SBC: call is established between mobile phone and Teams via SBC. Teams side ends the call, but this signaling (SIP BYE) never reaches mobile phon...

Same here for 100% of the calls. Scenario is when calling from external to Teams client. When the Teams side disconnects the BYE message never reached our on-prem Avaya SBC. We don't use Media Bypass. Setup is straight forward with only 1 SBC , 1 route pattern and 1 policy.

This must be something within the Teams environment. Any one any thoughts?

Thanks in advance.

    BTW, the SBC was on release 8.1.3 in this scenario.

        Alessandro_Gloria did you manage to fix this. We are also experiencing the same problem where the BYE does not appear to be received by the Avaya SBC. Teams ends the call but it stays open through the mobile phone.

    Hi Allessandro, this was resolved after updating the Avaya IPO to the latest release. In this release the line is not configured as SIP line but as MS Teams Line. Regards Jacco.
