[asterisk-users] Polycom IP430 HUM and Echo

I just implemented a Dell SC430, Sangoma A101, Adtran TA750 with 8FXO and
16FXS, and about 8 Poly IP430's.

Everything is working pretty well, however users are complaining about the
speakerphone quality and a loud HUM on the line.  I see in the sip.cfg that
gains are set to all kinds of wacky numbers.  This is the official
sip.cfgcoming from the
2.01 firmware release.  It has quite a few specific lines for the IP430 -
shouldn't these be flat?
