PSTN Call Drops if you put the call on hold then resume and hit transfer
Scenario
PSTN Call received on Teams Client, placed call on-hold , resume, click transfer and the call drops.
No changes anywhere, was working until a client drew my attention. Is anyone experiencing similar issue?
Hi jxace
Our root cause was someone had defined an extra sip port on the hosted SBC trunk in our Direct routing setup
The hosted SBCs were load balancing between 2. Unfortunately though, the fqdn in the contact header means this caused problems with TEAMS.
Our SBC provider disabled the 'bad' port - then all calls were fine in the respect of any ACKs or re-invites etc between TEAMS and the SBC.Not sure if this helps but good luck
Can you please see if disabling the New Meeting Experience you are able to resolve the issue?
A drop-down menu appears. Select Settings. The Settings window appears with the General section selected. Click or tap "Turn on new meeting experience (New meetings and calls will open in separate windows.
Uncheck the New Meeting Experience and check if we are able to use the services smoothly.

Tried disabling New Meeting and experience and unfortunately it hasn't resolved the issue.
I disabled the "New Meeting experience" then did a restart of Teams Desktop client.
When I hit the transfer MS seems to think I have hanged up as that what I see "Normal Call Clearing"
Thanks

Interestingly when I accept the incoming PSTN call on CCX500, I am able to put it on hold > resume > then hit transfer and it works.
I think it seems to be the Teams Desktop client.
Note ( I haven't tried Teams Web Client)
Kind Regards
