Does anyone know if it is possible to configure Asterisk in such a way that it will ignore RFC2833 DTMF signals received from a SIP peer?
I am using Broadvoice for some DIDs at the moment and their system has a tendency to mis-interpret DTMF digits, especially ones dialed from mobile or office (digital) phones. Basically, it will catch every digit dialed and send it to my Asterisk system, but unfortunately it frequently seems to repeat digits. That is, if I call into my system and want to enter a password of "123456789", Broadvoice will send something to my Asterisk machine such as "11234556789" or "12345567889".
I have set dtmfmode=inband in both [general] and [sip.broadvoice.com] in sip.conf, but from viewing the results of 'rtp debug', it appears that Broadvoice is still sending me the digits via RFC2833. I was thinking that if I could get Asterisk to ignore this and just detect the DTMF tones inband, that it might do a better job than Broadvoice's system.
If anyone knows how to do this, or has any other suggestions, I will be very glad to hear them. This problem has been driving me nuts. I am very satisfied with Broadvoice's voice quality, and I have a good network connection between my location and their SIP gateway, but more-or-less correct DTMF detection is fairly important for me and it basically does not work; but I really don't want to have to switch to using POTS lines for all inbound calls.
Thanks,
Rusty
