I've been using internetcalls for a couple of weeks with no problems, now I
get NU tone for every call.
:-(

So I open an account with voipstunt and use that - everything is fine.
:-)

Move back to internetcalls and still get NU tone - so going to use voipstunt
for now.

Has anyone else had these problems ?

Is it because I have an empty account ?

i.e. do they give priority to customers with money in their account for free
calls ?

I tried putting money in my account but it didn't like my phone number so I
couldn't get past the first page.
:(

Has anyone else had problems giving them money ?

tried area code + number, tried with country code, not sure what the problem
is.
