Running 3CX 8.0.10708.0 with a demo key, on XP SP2, dual Xeon 2.8ghz box. I have no VOIP provider and no hardware. Just using the 3CX Skype Gateway and softphones for now. I have the following issues. 1) If the mediaserver service is running, everything breaks. Extensions cannot call extensions, extensions cannot call out, calls in don't get routed -- nothing works. When I stop the media service, the system appears to work correctly (mostly.) Starting the mediaserver service results in me hearing my windows default error wav file, with -no- pop up dialog box. Once the first call is made or received with this service running, I hear the same windows error sound one more time (with no pop up dialog), and from that point forward, nothing works right until I stop that service. There's nothing in the logs indicating any error from the mediaserver service. 2) None of the system extensions are registered, other than FAX. I am using the demo key, which is supposed to unlock everything. This is a huge deterrent in convincing me to purchase the product. If I cannot test voicemail, call routing via the digital assistant, ring groups, API calls, etc., then I how can I evaluate this system properly?
