After more investigation, it seems my issue is not just with the accounting
module. Instead of proxying the 487 back to the original UAC, Kamailio
passes a 302. To simplify, I've removed the leg outbound from Kamailio to
the carrier:
0.000000 caller -> Kamailio SIP/SDP Request: INVITE sip:15202362038@Kamailio,
with session description
0.002294 Kamailio -> caller SIP Status: 100 trying -- your call is important
to us
0.002579 Kamailio -> LCR SIP/SDP Request: INVITE sip:15202362038@Kamailio,
with session description
0.038023 LCR -> Kamailio SIP Status: 100 Trying
0.046877 LCR -> Kamailio SIP Status: 302 Redirect Request
0.047807 Kamailio -> LCR SIP Request: ACK sip:15202362038@Kamailio
...
2.262195 Kamailio -> caller SIP/SDP Status: 183 Session Progress, with
session description
9.422170 caller -> Kamailio SIP Request: CANCEL sip:15202362038@Kamailio
9.424296 Kamailio -> caller SIP Status: 200 canceling
...
9.423958 Kamailio -> outbound_proxy SIP Request: CANCEL
sip:15202362038@upstream_carrier
9.487730 outbound_proxy -> Kamailio SIP Status: 200 canceling
9.576758 outbound_proxy -> Kamailio SIP Status: 487 Request Terminated
...
*9.579157 Kamailio -> caller SIP Status: 302 Redirect Request*
9.626503 caller -> Kamailio SIP Request: ACK sip:15202362038@Kamailio
This worked flawlessly in OpenSIPS so I'm sure it has something to do with a
difference since the 2 split. Any advice would be much appreciated.
Thanks,
Ryan

I'm converting my OpenSIPS routers to Kamailio
& have run into a small
complication. The proxy pushes all INVITEs to a least-cost router. This LCR
responds with a list of routes as contact instances in a 302 Redirect. Calls
are routing a serially forking normally. Connected & failed calls account
normally.
However, if the caller cancels the call, the acc module includes the 302 in
the transaction record as the final response as opposed to the actual final
response - the 487 Request Canceled.
Is there something I could be missing that would cause this?
Thanks,
