I’m incurring problems in DTMF asterisk 1.4 - FreePBX 2.3.1 (Trixbox 2.4 machine)
I have 11 telephone numbers registered.
All the numbers expect one work fine with RFC 2833.
With the damned number IVR doesn’t recognize when I digit numbers.
Seems that the DTMF tones are not passed, infact, using a sip client, I discovered that the IVR works fine if I set DTMF in “SIP INFO” mode.
The problem is that I tried to manually change DTMF in extension.conf (dtmfmode=info and dtmf=info). I tried relaxdtmf=yes… nothing change
Codec: alaw and ulaw
Any tip?
Thanks in advance,
Regards.
