AW: AW: [Asterisk-Users] DTMF detection when outgoing call tomobilephones

[Marc Scheuffler]

Actually I am using Asterisk 1.2.7.1, zaptel 1.2.5, libpri 1.2.2

I ve tried many values for rx/txgain togeher with echocancel and relaxdtmf.

The detection is not working with call file, manager originate and not with the dial command to the mobile.
I have no ideas left.

I got it sometimes to work if I use a specific channel (i.e. Dial(ZAP/14/...)
But with the same vaules on a second call there is the DTMF problem again.
Sometimes the DTMF tones are choppy at the other end of the line.

There is also a Warning with outbound calls only:
 -- Called G1/016080...
    -- Moving call from channel 2 to channel 31
May  5 12:45:33 WARNING[1403]: chan_zap.c:7744 pri_fixup_principle: Can't fix up channel from 2 to 31 because 31 is already in use
May  5 12:45:33 WARNING[1403]: chan_zap.c:9045 pri_dchannel: Unable to move channel 31!
    -- Zap/31-1 is ringing
    -- Zap/31-1 answered Zap/2-1

But everything is ok and working on not moblie connections

There was a bug in various versions of Asterisk when outbound calls were placed using spool files and then could not detect DTMF from the called party. Without more details, including the version of Asterisk you are running, it will be difficult to suggest anything to you other than upgrading to the latest release.
