David, just to add my $.02 here... I had the same problem you describe (about 2 yrs ago). I also use a 4-port Sangoma card, however, this was a problem with both analog calls and calls routed via my SIP provider. I just looked at my sip.conf and see the following being used for all extension phones:
rfc2833compensate=yes dtmfmode=rfc2833 The sections for my SIP provider specify: rfc2833compensate=yes dtmfmode=auto I'm not certain if this is the best way to configure DTMF, but I haven't had problems of this kind in quite a while. I'm now running astlinux-0.7.10 (Asterisk 1.4.42) -tm -----Original Message----- From: Lonnie Abelbeck [mailto:[email protected]] Sent: Wednesday, February 08, 2012 9:21 PM To: AstLinux Users Mailing List Subject: Re: [Astlinux-users] DTMF Issues. Hi David, DTMF issues can be tricky with all the interconnected parties involved. Usually your best choice is "rfc2833", while "info" (SIP Info) may also work and both are out-of-band signals. "inband" requires a uLaw/aLaw codec and some luck, not recommended. Pick one and disable all others. AstLinux 1.0.1 should have the same Sangoma drivers as 0.7.x. If you upgrade and there are problems, simply revert *both* the firmware and RUNNIX via the System tab, and reboot, you should be back at your original 0.7.7. AstLinux 1.0.2 (when released) will have updated Sangoma drivers for DAHDI using libsangoma. While we always encourage users to upgrade to the latest, we can't test all possible hardware combinations, so while things should work fine, but be prepared to find and fix problems.
