I have a 2talk account with a Grandstream Handitone setup. It has been working satisfactory(just) for some time.
ATM we don't seem to be able to get through to make overseas calls. It has a ringtome(same as for national call) though I suspect it does not ring on the other side.
Has anyone of you an idea what that could be?
Haven't contacted 2talk as the waiting time is most likely as long as waiting for the last year's snow fall.
