CS 1000 PBX CS 1000 PBX Aklile Tefera (Instructor) (OP) 3 Jul 23 13:50 what is the main case my CS 1000 PBX can't make out going calls receiving is fine . any advise. RE: CS 1000 PBX Firebird Scrambler (Programmer) 3 Jul 23 15:12 The initial question is whether the customer has paid their phone bill. If not, then most suppliers would block outgoing calls. If outgoing calls go out via LCR (Least Cost Routing) that is a third party, then try another access route. Failing that, find out what connection type is used and if its a digital trunk card to check its all green on the LED's. Log into LD 80 and set up a call trace. Also check if your outgoing RDB has more than one entry as it could be that calls are failing because a circuit has recent been ceased that was primarily used only for outgoing traffic.
