Thank you all for the pointers. I have Vonage, but calls to Iran still is expensive. It is 17 Cents a minute. Sometime use Skype too to land line. You know how it is for new year, I have to phone to all my cousins , khaleh and Ameh and it adds up. I will try all your suggestions to see which one is better as there is no shortage of telephone calls.
Ali jan do I hear this right that you are in US now? any plan to come to Seattle so maybe we can meet up and have a pint and lunch.
