I just ran a FreePBX Asterisk Version: 13.27.0
Known an annoying echo generated by some VoIP Gateway [Grandstream GXW4108] but I can not handle …
I have documented and it would seem that our beloved FreePBX has weapons to compensate for the problem …
I saw this post that looks interesting: Hard ware echo cancellation problems
Now the /etc/asterisk/chan_dahdi.conf file is not present
But I found a file /etc/asterisk/chan_dahdi_additional.conf but empty
I can put there some parameters like:
echocancel = yes
echocancelwhenbridged = no
What are you saying on the right track?
Can I do better?
I await reply, thanks to all
