[Serusers] SEMS instead of CC-Diversion

Hello: I have been trying to get the CC-Diversion header working so our proxy can interface with our existing Octel voice mail system. Due to a series of incompatibilities between Cisco and Verizon's DMS100 I have been forced to give up. I'd like to revisit SEMS as an alternative. I have SER and SEMS both installed and running but I am at a loss for how to forward an unanswered call to SEMS after N rings. Can some please explain this? My first attempt to use the existing failure route block generated several of the following messages. Jul 7 12:58:28 ser: parse error (642,19-20): Command cannot be used in the block Thanks,Steve
