The times I've seen this fail have been when the phone is behind a router 
with a broken SIP ALG. Make sure the ALG is turned off, if possible, and 
look into using a STUN server to let them phone know how the NAT firewall 
is working if the remote isn't behind a proxy. And if you are already 
using STUN, make sure the phone isn't trying to use STUN for the internal 
connection - it's programmable on a per-account basis in the GXP phones.
