[Freeswitch-users] DTMF filter (RFC2833)

[Mickael Hubert]

Hi list,
I'm looking for a way to filter ingress DTMF on A leg.
I receive "bad" DTMFs from SIP provider (Signal A,B,C, etc ...) I want to
filter only these DTMF, not all others.
I receive only RFC2833 DTMF.

Ex:
Sip Provider -- (DTMF 1,A,2,C on A leg) --> FS --> (DTMF 1,2 on B leg) -->

Do you have an idea for me please ?

Thanks in adavance
