Hello,
Can you tell us what type of GSM modules you are using?
Type "gsm show span X" on the console to get the GSM module information, where X is your SPAN number.
If you are using M20.conf, can you insert the following line into line 66 in file /etc/openvox/opvxg4xx/modules/m20.conf?
AT+QECHO=221,2048,0,849,0
Save and exit it. Then, restart Asterisk and see if it takes effect.

After following your recommenations echoing has indeed stopped on Span 1, however after installing another 2 SIM cards (Span 2 and Span 4) the echo has appeared again (the operator does hear their own voice but there's no echoing on the client's side). Please advise how echoing can be supressed on Span 2 and Span 4.
