[Serusers] HELP: SER-0.9 Record Route Problem Between SER and Asterisk

Hi All. I'm using ser-0.9 Can anyone take a quick look at this short SIP conversation and tell me if they think the problem is with my ser.cfg or a bug in Asterisk 1.0.2. We use a 3rd party for PSTN gateway functionality. This 3rd party uses a Sonus box behind a SIP proxy. Our SER proxy talks directly to their SIP proxy as needed to complete PSTN calls. The problem is that when a PSTN caller dials a SIP phone and gets sent to voice mail (Asterisk) because of a no answer or busy condition, Asterisk hangs up after the caller leaves a message. When Asterisk hangs up, the BYE from Asterisk is sent to SER, however, SER incorrectly forwards the BYE directly to their Sonus gateway, rather than the their SIP proxy. This causes our PSTN gateway provider to have "open" billing records in their system. If you look at the BYE message from Asterisk to SER you can see that route headers are missing (I think). The final BYE should have been sent to 68.86.100.20, but it was sent to 68.86.100.30 instead. I am record_route()ing all messages except for REGISTER and I have the mhomed=1 parameter set. Can anyone help me put the blame on either my ser.cfg or Asterisk?
