Has anyone have this problem,
CTX100 with DID (analog) Telco switch AT&T 5E, Installed in July, starting in late Sept. DID calls inbound only the person answering the call can not hear the caller. Teleco said it was our equipment, we replaced the RDDU Card and no change? If I get on the circuit at the DMARC and dial in everything works ok, if teleco does a test from the test board it works ok? Set for wink start and we have 3 circuits and all three do the same thing.
any ideas would be great?
