Hello Joe,
I'm using chan_extra 1.2.1 ... The /etc/openvox/opvxg4xx/modules/ directory does't exist in my directory..
The source installation directory is /root/src/asterisk-complete/chan_extra/1.2.1/src/opvxg4xx/ .. I'm not sure if this is what you're referring to.. however, there's no m20.conf file.
Hello Juan, Please forward to your source directory and find about line 887 and 893 in file m20.c
There is AT command AT+QAUDCH, and its values are:
AT+QAUDCH=0 (NORMAL_AUDIO)
AT+QAUDCH=1 (HEADSET_AUDIO)
AT+QAUDCH=2 (LOUDSPEAKER_AUDIO)
AT+QAUDCH=3 (AUTO)
By default, its value is 1, can you switch its value to other and see if it's useful?
Or set "AT_CALL_PROCEEDING =>" from "AT+CLVL?" to "AT+QECHO".
