Calls dropped when hold or transfer

[felixnutella]

Hello

Sorry for bringing this up if it has already been asked. Have searched the forums for an hour without any luck.

My problem is using a 3CX Softphone with Tunneling the calls are dropped when I try to put them on Hold or Transfer them. I checked the Debug window and I get a 488 - Not Acceptable here.

Does anyone know what might be wrong ?
