Your config files?? Zaptel zapata ? Maybe you have a setting wrong i had the
same problem but then with pri lines now it's gone. You can hear yourself as
loud as the other person that is calling you? And what sipphone do you use

How could I have done that? I'm not recording any sound (at least nothing
i'm aware of). The echo doesn't happen when the call is incoming from SIP
provider (instead of PSTN) - so i assume the problem is related to the
analog line. The SIP phone is stand-alone AT-320
