EVA VideoPhone is a SIP-based softphone, developed as a part of a new generation VoIP platform by Verysoft - company with almost 10 years of a VoIP development experience.
EVA was designed to provide a customer with the best video and audio quality even not on very good channels, save battery and be fully compatible with SIP providers and other softphones. The product was optimized for WiFi, 3G and LTE.
NOTE: EVA VideoPhone for Android is not a VoIP service, so it requires a SIP account in order to be able to place a call.
