The bye packet is broken as you don't have the username part on the
Route header uri.

I haven't worked with these phones but it seems to me that they are
doing strict routing like some pre-rfc3261 devices.  In "normal" case,
the first line would have looked like:

BYE  sip:user at 210.68.65.78 SIP/2.0

without the route header.

Hope this will help.
