Whenever I make a direct outgoing call to Iran I hear a music. It is happening on my both of cellphones and also from my Fido wireless home phone. It doesn't matter which number I call and same thing happens.
This issue started few days ago and I am not sure why. I did not make any changes to the account nor to the devices.
If I use a long distance calling card then the calls will go through but not when calling the numbers directly from my devices. I am not sure if there are long distance calling blocks added to my lines.
