[Serusers] SEMS issue

I just updated and rebuilt my SEMS source from cvs. SEMS starts ok but when an inbound calls is relayed to SEMS I get a reorder tone and the following log messages. I didn't see any mention of this in the list archives. Can someone explain what is happening? Thanks,Steve 8396@128.91.50.49:5060>> Aug 23 14:20:15 voicesrvr ser[28966]: [SER_vm]: URI match.
