Loop Start T1 through PBX from Dialogic card

(Anyone) familiar with configuring a Loop Start T1 through a PBX from a Dialogic card? I've got it to see the T, it talks, it initiates calls, but they don't connect completely. Incoming calls just ring and ring but the software shows connection. Thoughts on troubleshooting? Thanks in advance Louis _______________________________________ Louis M.
