I would suggest you grab a "sip set debug on" trace for this issue to 
confirm that the signaling is fine. When the phone answers it should 
send a 200 OK to Asterisk and then we respond with an ACK. If that all 
looks correct, as it seems to from the log you have provided thus far, I 
think you may have a phone specific issue.
