Hi, i have 3cx 7 (downloading the latest update right now) running on a virtual server on vmware esx, i have gave the 3cx server a promised 1.5ghz of proc and 2gigs of ram up to 4gigs of ram and up to 5ghz of proc. Also the only thing running on this vm is 3cx. network runs on 2 switches, a dell gig switch and a hp 10/100 switch with a gig uplink to the dell. both switches have qos setup for the ht503 gateways with highest priority given to anything coming or going from the 2 gateways and the 3cx server. I have 2 ht503 gateways, using them for 2 pstn lines and 2 analouge phones, also have 1 sip phone. i have 2 lines, one is used for faxes and i dont let the gateway answer on this line only call out, the other line is my second outgoing line and of course the only incoming line. The ht503 gateways have the latest firmware on them to my knowledge, 3cx is being updated at the moment. My problems are that on occasion when making a inbound call the gateway will ring, answer, and then 3cx will never start talking, you can hang the phone up and try calling agian and the line is busy and the gateway is completely locked up, can no longer access web interface and cant even ping the device. if you look at the device sometimes the "line" light along with the wan and power lights will all be solid, and sometimes the "phone" light will be on. I have swapped devices to make sure that i didnt have just one bad one and both do it. So im not sure if 3cx is locking it up or if the analouge phone is causing it or what? I can also look at 3cx trunk status and it shows as registered and idle. Also second other problem is that somewhere somehow either the gateway or 3cx is occaisionally calling 911 when no one at the business is even on the phone? Im not sure if this is triggered by a inbound call or not, this has happened about 3 or 4 times. My other issue is that if the system has not been called in a while the auto attendant takes a bit longer to answer than id like, but if you turn right around and call again it is very prompt on answering? Any help would be greatly appreciated, ive been seriously thinking of switching to a linksys spa3102 but i hate to spend the extra money.
