Have free VoIP phone calls to everyone but one thing still not really free. It calls as VoIP numbers and addresses, the landline and mobile numbers. It is very rare, almost impossible, to get free calls to landlines and mobile phones. Some services offer, but with conditions. I briefly checked three services that probably identical, offers similar, free calls to a certain number of international destinations in the fixed network. Interesting at first thought, but then when you read the fine print, you see that there are obstacles.
You must use for VoIP cheap and free call first, buy credit that call other non-free destinations. Then you may call free free destinations in the gold list. Additionally, you must not more than 300 minutes per week free of charge. VoIP stunt is more generous. 6O minutes before buying it offers credit for new users, then the 300 minutes after filling up. Only examples, carefully to his and takes into account all aspects of VoIP service are before a decision is taken.
