Video telephony, calls to landlines, short messaging, and conferencing: the free Wengophone outpaces competitors in the VoIP field.
Linux isn’t exactly short on VoIP solutions. Unfortunately, many SIP-based tools do not support encryption and will not work without router and firewall manipulation. Some time ago, Skype caused a stir in the open source market with a proprietary Linux client. Prospects for a full-featured open source phone tool have improved with the appearance of Wengophone. which was originally designed to operate with the French Wengo VoIP provider. Wengo users with the current 2.1 version can call each other free of charge; they can also call landlines, call cellphones, use video telephony, send various text messages, and hold conferences.
