Just execuite in the dialplan: Set(DAHDI_IGNORE_INCOMMING_DTMF_DETECT=1) DAHDI_IGNORE_DTMF_REGENERATE is used for outgoing calls. dahdi won't touch the audio and won't make any dtmf frame. You must solve it on other leg of the call (SIP, ATA etc). On SIP: set ATA inband sip mode, asterisk: set rfc2833. When you need dtmf conversion from/to ATA change the dtmf mode in the dialplan with SIPDtmfMode() application (on called channel via the U(x[^arg]) dial parameter). I have stupid MGCP/NCS ATAs, they don't touch the audio just create a NTFY message for dtmf, I ignore it in chan_mgcp with similar whay. These solutions are very ugly, but works the alarm systems fine, playing with DTMF modes alsa working the my dtmf controlled ivr builtin services (balance query etc...)
