Summary: Transaction matching causes CANCEL to fail

Initial Comment:
The new transaction matching code in 1.3 for CANCEL does find a match as shown below, however the CANCEL is not relayed to the device that is to receive the CANCEL.

DBG:tm:t_newtran: T on entrance=0xffffffff
DBG:core:parse_headers: flags=ffffffffffffffff
DBG:core:parse_headers: flags=78
DBG:tm:t_lookup_request: start searching: hash=14478, isACK=0
DBG:tm:matching_3261: RFC3261 transaction matched, tid=7b84a7f5EE519894
DBG:tm:t_lookup_request: REF_UNSAFE: after is 2
DBG:tm:t_lookup_request: transaction found (T=0xa7bd2074)
DBG:tm:t_retransmit_reply: buf=0xb7b71c40: SIP/2.0 2..., shmem=0xa7bd3c0c: SIP/2.0 2
DBG:tm:t_unref_cell: UNREF_UNSAFE: after is 1
DBG:tm:t_unref: UNREF_UNSAFE: after is 1
DBG:core:destroy_avp_list: destroying list 0xa7bd4148
DBG:core:qm_free: params(0xa79a8000, 0xa7bd4148), called from usr_avp.c: destroy_avp_list(390)

The same processing on a 1.2 system produced the following.  It clearly shows the "end-to-end" cancel proceeding. The device at 192.168.1.99 is the correct recipient of the CANCEL.

DEBUG: t_newtran:  T on entrance=0xffffffff

Detailed sip traces and logs have been provided "offline" because of their private nature.
