Hi all, I'm experiencing an issue with IVR on production Freeswitch cluster. I'm going to explain the problem as clear as possible just to understand if anyone already get it and hopefully fix it. Phone A makes a call that match an IVR services: call is transfered to context services in xml services. Call is then answered, audio menù is prompted: phone A makes a selection (ex dtmf 2) and the call is trasfered to context default xml default in order to ring phone B. If phone B is in busy state the call is dropped. On cli logs you can observe this behaviour: Mod Sofia first hangup the channel with a USER BUSY cause and then it sends a BYE to Phone A (or to a gateway in case of external calls) including Q850 cause=17 user busy. Phone A or Gateway drop the call without busy tone. In this case I'm expecting a SIP 486 (user busy message) instead of a bye, is that correct? I'm using the app "limit" in order to count active calls on extensions and store them in system db (shared between freeswitch servers). Hope you can help me solving the problem. Thanks Regards Francesco
