Hello. At this time i've got the free 3cx version running fine on my business 2003 sbs server. I use it with 2 sip accounts and 5 voip phones. Everything runs like it should. The only problem i have is that i have to reboot the server each day because 3cx looses connection to the sip accounts (or something) When i get to the office in the morning and look in the 3cx logs i cannot find any special. Both sip accounts show as registered, but when i call one of them they are not reachable. When i reset the server it's fine for a day. But on the next day it stopped working. What could this be? Except for 3cx the rest on the server is running fine. It doesn't loose it's connections or something. My dsl provider uses dhcp but only changes it about one time per month. When i do the firewall check it passes, except when it's not working, then it says it can't detect the stun server :S. Anyone knows what this could be? I've already tried reinstalling 3cx.
