When you get a 'busy signal' from a VOIP call, have any of you checked to determine if the called number is actually in use?
At first I thought my VOIP provider was working flawless. When I got a busy signal I just assumed the number I was calling was busy. Then it started dawning on me that some of these numbers should never be busy. If they're in use, they trip to voice mail.
Now when I get a busy signal, I try the number using my POTS line. If it rings and if I'm not in a hurry, I hang up and hit the re-dial on my voip phone. I'm finding that more then half the busy signals I getting when I use VOIP go thru when I use POTS
Has anyone done this test and if so what have you found ?
