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.

  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.
