Microsoft dropping calls when attempting to pickup call on hold #426

Closed danry25 closed 2 years ago

danry25 commented 2 years ago

Issue: I can place calls on hold, but when going to retrieve a call on hold the call drops. Microsoft appears to end the call out of the blue, though the caller does not hear Microsoft's Music on Hold and this issue only started with the user agent updating to USER-AGENT: Microsoft.PSTNHub.SIPProxy v.2022.2.21.3 i.USWE2.0

Microsoft sends this in the BYE (as shown in the picture): REASON: Q.850;cause=22;text="7dbc8050-a506-436e-9f97-01f0e44930fd;BackToBackSessionDeleted" Screenshot from 2022-02-24 12-02-26

Platforms Tested: dSIPRouter v0.63 and v0.642 Teams Android and iOS

This issue has been remediated by Microsoft with the release of SERVER: Microsoft.PSTNHub.SIPProxy v.2022.3.4.9 i.JAEA.1 (from the dSIPRouter logs)
