I expected the switch to see the line as "busy" during a circuit failure (or Adtran failure) but it did not. It saw an error condition, and did not forward the 0200 calls to the off-site answering service.   In speaking with Pete, I understand LDMI uses a DMS switch. I believe there is functionality in the switch to do "failsafe" routing. So that if a line is down for whatever reason, the calls can be automatically routed to a backup number.   See:   http://www.focal.com/prod_serv/failsafe.html   Implementing this feature would be a good customer service idea, and could generate extra revenue for LDMI (charge a small monthly fee for the service).   In any event, we will need to develop a procedure and process to deal with outages on the T1, such that our customers can always reach us.   I'm interested in your ideas on how to accomplish this.   Thanks, Tom
