2) You need to have a 'test call' option.
It seems that it already has that option
[you just have to dial "801" and it doesn't require having an account].
- @limikael: Is the actual quality similar to what I've heard on the test call [the delay felt like a couple of seconds (not sure if it has something to do with my net)]?
I would suggest that you add price rates for calls, so I would know how much I need to pay for one minute of conversation, or something like that.
When you type in a correct/valid number, it'll show you the rates beneath the number
[not sure if it was added recently].
