[Freeswitch-users] problem with hard phone

[Michael Jerris]

Your log below seems to indicate this is a codec negotiation issue, I doubt it has anything to do with the port thing you mention below.  The message below looks like your phone is requesting g722 at 16000hz.  This would seem logical as its a wideband codec.  There is a long ugly story behind this, but the rfc requires everyone to lie and say 8000hz on g722 instead.  Your phone seems to not be following this rule and I think that is the cause of your issues.  You should update your phone to some firmware that fixes this bug, correct it with some configuration setting on the phone, or disable g722 on the phone altogether.
