When I call a person, I can not hear the phone ringing, but, when I ask the person that I just called if their phone was indeed ringing, they say yes, it was, I just can not hear it ring. To weird for me. I would think it is on Voipo's end, not mine.

As far as the firewall goes, Voipo said that I am good to go. They took control of my computer, and set it up as I watched, so I would assume that the problem is on Voipo's side.
