Eric:

You need to decide what application will provide voice mail service
SEMS, Asterisk, etc. That decision will drive what needs to be in your
config file. Basically you'll need to add t_on_failure("N") and
failure_route[N] statements to handle the unanswered call. In the
failure_route you will want to do hostname and/or port number
re-writing as necessary then t_relay the call to this new (voicemail
server) destination.
