hi,

i have a SIP gateway which doesn't support info or rfc DTMF so im forced with using inband so in my dialplan i use start_dtmf_generate to translate from info/RFC used by IP phones to inband so gateway can send that ahead, the problem i face is im using bind_meta_app to start a on demand recording using *2 so when the local extension presses *2, the * DTMF still goes to the gateway inband and 2 is never heard by callee. What i want is to filter out the complete *2 so the callee doesn't hear those at all but i dont want to drop all dtmf from going to gateway.

Is there a way to filter out selective DTMF like the * or any other star codes used in bind_meta_app etc?
