Subject: [Users] Accounting Bye packet Issue

I am facing a peculiar issue with accounting. BYE packets are getting rejected
with error message: 478 Unresolvable destination.

From your logs, I see:

U 59.176.78.110:50496 -> 210.68.65.78:5060
BYE sip:210.68.65.78 SIP/2.0.
Route: <sip:@209.67.171.10;transport=udp>
               ^^^^

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

This happens only in case I use ATA for calling and with some gateways only.
With the same gateway if I call using xlite, accounting works fine. I am
unable to find out the reason.

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:[EMAIL PROTECTED] SIP/2.0

without the route header.

Hope this will help.
