I have a Digital Trunk programmed for a dialogic card. If you call internal the route/DSC works, if you call from a cell phone or call the DID from our cs1000 it works. If you call from a residental or POTS line it goes to the operator "0". I have checked all of the programming and can't figure out why some calls work and others do not. I can post any copies of the RLI, DSC, RDB programming as needed. Thanks in advance for any help!
