Look at the route header generated by the cisco: It's broken

Hi,
I am facing a peculiar issue with accounting. BYE packets are getting rejected with error message: 478 Unresolvable destination.
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.
Can someone help on this?
I am attaching the log when I am calling from a ATA and BYE is being rejected by openser.
Regards
Dan
