Xgen Say

Xgen SAY app provides enterprise class audio/video calls. Xgen Say also works with XgenPlus email server so you do not need mobile number or any other phone number to install the app and make a call, you just need email address and internet to talk to someone. So if caller and recipient of the call have WiFi or 3G/4G internet connection, both can talk to each other with audio / video calls.
