For 6 hours now, friends are having to call on cell not in the simul ring to get me. They call the voipo number and get 1.5 rings then a fast busy. Same when I call from a cell to my voipo number. Nothing on my end rings, not even the simul ring number. All incoming calls are showing on the call log for 0 seconds duration. I can call out ok.. 4 hours since I put in a service request and nothing back from them yet.
