We have 3Cx setup on a Windows 2003 server. Calls come in via VOIP, ISDN and a Portech GSM gateway. Currently all calls are routed to a queue with a dummy extension (never logs in) with a time out to a ring group. This is because 3CX does not have a ring all from a call queue (there are many posts about this workaround). Everything works fine - most of the time. But occasionally, a call seems to get stuck in the queue - the caller hears the MOH but no phones ring in the call group. After the queue timeout, they hear a message saying 'trying to connect your call' and then the phones ring. All extensions are set to 'Use Phone status and the extensions are mult-line Linksys phones. It doesnt seem to matter what the origin of the call is (ISDN, GSM etc) nor the time of day nor how busy it is. Its very difficult to get a copy of the server log because we dont always know its happening. However, because of the message it seems clear that the call is in the queue, but 3CX isnt getting around to calling the ringgroup. Anyone had a problem like this before?
