I live in USA and my family in Mexico, thay have been using voxalot and voipbuster for 1 year at least, but since 7 days ago, thay are not able to dial out via Voxalot Dial plan, apparently there is a problem here as everybody have mentioned. The wired thing is our calls Voxalot-voxalot works just great as always, When I dial out via dial plan-Voxalot, I have no problems, I have a Sipura, but when my family try to dial out they get the busy tone, it was working ok but something happened, they have a cheap ATA I bought for them
so I can deduct it is some issue with the device itself. Even the WebCall does not work. Awkward, I hope a solution comes soon.
