If you are a CallCentric user as I am, you might notice sometime there is a fairly long period of silence (30+ seconds) after dialing an international number. The ringback tone comes so late that makes you wonder if the correct number has been dialed. umm...
Well .. happily see no such a problem with GV. After setting up GV on OBi110 yesterday, with the initial $0.10 in the account (roughly 5 minutes international call), the first attempt was great! The ringback came right after the dialing, and voice was loud and clear, and no much delay ... good reason to add credits in GV accounts ..
