Hello humans of IMT forum. I have a special offer for you. Here it is. This site allows you to get free calls for many international destinations. Call duration depends on the country. To Russia its 1.5 minutes.
2 calls per day. If you like, have a try.
If you need more calling time, have to buy credits. I think this is cheaper than skype. Voice is very clear almost same as the skype.
Registration is not required for free calls, however you can register too
