I am sitting at a client site right now with 3CX version 8 running on server 2003, 2 patton SN 4114's to the PSTN (US). The calls are going crazy coming in. Some calls I get "ParserError. This Shouldnt happen" and points to one of the caller ID lines. Other calls just hang up after 1 ring, and still other calls just ring and ring. This is urgent. I have re-generated the config files and re-deployed them. I have tried firmware 5.2 and 5.4 with the same effect. Outgoing calls are ok. Incoming calls either ring, crash with some parser error in the caller ID, or hang up after 1 ring. What should I try next?
