Z4 Mobile App for iOS
'In addition to making and receiving ZVRS calls, the Z4 Mobile app allows deaf and hard of hearing people to make and receive point-to-point calls to and from any videophone. Use your iPhone 4, iPad2, or iPod Touch 4th Generation to communicate with friends, family and business contacts—hearing or deaf—anywhere WiFi or 3G is available. (To ensure the best video quality for your calls, WiFi is strongly recommended.)
How It Works
Choose to place a call from your contacts list or by manually dialing the number you would like to call. If it’s a ZVRS or VCO Plus call, the video interpreter will establish the video session and connect to the hearing caller. If it’s a point-to-point call, you will connect directly to the other caller’s videophone.'
