G.711 is an uncompressed codec, so this is the best quality available.

Mee too.... I am a ONE FULL WEEK expert ( :-)) ). I have discovered FWD
from
the original mail on this list about a week ago (more precise your mail
from
Mars 7th) and now I am very attracted by Internet Telephony and especially
SIP.
My chance was to get for some time a couple of good Cisco Phones and I am
impress with the quality of the conversation.
In between I have done some teste with Cisco 7960, Cisco 7940, SJPhone,
Windows Messenger and iPaq version of SJPhone.
Who wants more details, I kindly ask him to send me a mail directly,
eventually to make some tests.

Dan
