I am unable to make phone calls with the WebPhone, which may be the problem?

First of all make sure you have sufficient credit to make the call. Please note that your credit balance is always displayed in the box at the top right when logged on our website.

Verify that you typed the number correctly and the destination is normally reachable.

If you're using a Linux operating system check also that the audio devices are not in use by other programs (like an music player, video and so)
