How to debug a TDM connection

Hello all!I am using a VWIC card with Drop&Insert in a 3600 and a 2600 to configure a Voice and Data TDM connection. Data connection is up and working OK, but channels reserved to transport voice are up but not working at all. I don't know how to debug the connection. Has anybody use TDM feature of these cards?
