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 .
