[Asterisk-Users] Echo in CAPI channels

[Robert Rozman]

Hi,

I have exactly same problem. I hear echo (I guess it's more like reverb) but
only if calling from analog phone.

I've already asked this group about it, but didn't receive any solution
answer. Maybe we should try to contact avm or something. I also didn't find
any more info what these all setings in systems and Asterisk' capi
configuration files are....

If you find anything, please keep us posted....

Regards,

Robert.
