Make free Calls to India and Worldover with Zenring

Zenring is a very new company which recently kept its foot in the VoIP service market. With this service you can make unlimited international calls or with the rate of local calls. You can also go for PC to PC calling or phone to PC calling or vice versa with this service, but since it a VoIP service after all, don’t rely on it for making emergency calls. However unlimited calls can be established only between Zenring users and apart from customer’s PC, broadband internet connection and a landline connection, both the calling parties need to have a special hardware USB device called Zenpal.
