[asterisk-users] DTMF detection during Call

[chrigu at lorraine.ch]

Hi

I have calls comming from a SIP-ATA-Box via Asterisk to PSTN Phones by
outbound SIP.
Now i want to detect DTMF-Tone Code coming from the called party to
trigger a signal.
Can this be done with asterisk? I read that the codec with DTMF
detection are ulaw and alaw. But i couldn't find a command to detect
dtmf's within a normal call.

thanks and mani greetings
Christian
