I managed to resolve this issue by working with the SIP carrier, they hadn't approved Teams on their trunks so we had to start from scratch and now have a working config.

On our Audiocodes SBC I have the SIP Trunk IP profile set a specific way for hold and retrieve, see attached screenshot.

There is still a time delay when resuming a call but this is an MS issue that they are aware of.

I have the same problem. When I press resume nothing happens, no message on the SBC. Call Transfer is working, Consultative Transfer is working.

  Hi Alex_Dunlop and Flavio_Goncalves! I am in the same boat! In another thread, I found could be de Call Parking Policy. Tried, no sucess. The interesting is when I do Consultive Transfer, the call goes normally to "hold" and I can resume It without problem!
