hang call, sip call <-> FXO <-> PABX <-> PSTN

[cnicules]

Hello,

I have an VoipGW (3725) with FXO, the line goes to the local PABX and from there to the operator, in the voip part i have a sip_softphone.

the call establishment and conversation works very well, but the hangup part don't.

If i hangup at the PSTN part the GW don't detect the hangup so he keep the connection, eventuali at the end i hangup on the softphone and now he free the line.

the second case, If i hangup the softphone first all goes well, and on the pstn phone i have the busy tone, like it should be.

so any ideas???

If you are using Loop Start FXO type have you tried setting the FXO port with Loop Disconnect supervision?
