mgcp open fxo port before extension answer the call

Hi,

I have customer complain that fxo port open before the extension answer the call which cause the call to be charged by telecom company

 

the gateway is registered with call manager using mgcp

so is there any configuration like opx in h323

Will probably need some

Will probably need some debugs such as "debug vpm signal" so we can see what is being sent out on the analog port for one of these calls.

There is how FXO port will

There is how FXO port will answer the call, as soon as it gets an setup indication on the wire, it would go off hook to establish the call on IP Leg.

 

you may also see the behavior, when an IP phone makes an outgoing call via FXO port, call shows as connected on IP phone, whereas called number is still ringing.

 

Behavior may change when configuring answer supervision on voice-port. But one drawback which is been usually seen is caller that ip phone callers missing ringback on PSTN calls.

 

Additionally below said debugs would help more.,

 

debug vpm signal

debug voip vtsp all

debug mgcp packets ( Assuming you are still running MGCP )

debug voip ccapi inout

 

Thanks,

Amit
