We're down. Ringroost is not working.
We're down too, but for this exact reason I've set up our phones with a seperate service provider, Callcentric. I have our main office number with Callcentric and route all the incoming calls to the ringroost PBX. If the PBX is down, which it seems to be periodically. I still get incoming call rings on the Callcentric line on our phones, and can make outgoing calls on that same line. I just don't have the abilty to transfer calls and other fancy stuff like IVR, etc.
You kind of get what you pay for. I'd get a backup plan if I were you.
