G400E echo

Hello Svaadm,

Did you try to reload/restart the asterisk?

Normally, it (AT+QECHO=221,2048,0,849,0)will apply to the whole GSM card for all the modules when asterisk starts.

Yes, I rebooted the server completely to install sim cards.
Is this setting applied to all module channels?

Yes, it applied to all the M20 model. Actually, it will automatically recognize the module model and enable different *.conf files in /etc/openvox/opvxg4xx/modules/ even if you have some types of GSM modules in the same machine.

Could I have your remotely access ID now?

Hi,

Can you remove the line "AT+QECHO=221,2048,0,849,0" firstly and see what happens by default?

Hello.. I'm having echo problems too with the G400P.
I have an A400P and G400P installed in the server.. the A400P works fine.. G400P works, but has an echo..
Two modules M20 GSM101 are installed in the G400P.

I can't find the m20.conf file to add the echo line described in this post .

Help!
