I would try if a I have more time. Nowadays I have problems with the
sound quality in the conversatio. 7941g with SIP-8-0-3 firwmware sounds
well but 7911G with the same firmware version sounds really bad in an
Asterisk 1.2.15. I listen echo and noise taps when I talk with other sip
users of the same Asterisk.

I have test the phone with the same firmware againts the lastest version
of Asterisk (subversion stable tree) and there is no problem with the
sound quality.

Do you know what is the problem in this case? Or if there is a bug in
Asterisk 1.2 that could affect in that way the audio quality?

Thanks,

However againts the 1.4.17 version there is no problem
