DTMF digits ignoring by option?

Question

The problem is when i call from my the mobile phone to my asterisk form extern line and try to choose internal number like example number 1 = 101 or 2 to call = 102 then get log like this below

my version of asterisk 11. + lcr + mIsdn

[call=1122 ast=lcr/1] Recognised DTMF digit '2' by LCR, but ignoring. (disabled by option)

What option i have to enable? or maybe its wrong dialplan or can be problem with Dtmf options, for now i set for INFO still not sure. i never found any similar error .

Answer 1

This means that you are receiving in-band dtmf but the detection for this is disabled (dsp_dtmf).

Most probably you have disabled DTMF in extensions.conf.

Check if the option is not accidentally set to “n” (and remove it or change the setting).
