VoIP for emerging devices

VOICE OVER INTERNET PROTOCOL (VoIP) services that promise higher audio quality, richer feature sets and potentially lower cost are attractive to both end-users and service providers. Users can enjoy voice within an extended communications suite, and service providers can mix voice with other IP services to make their offerings more compelling to the user. While VoIP services have traditionally been consumed within the home or office environment, it is desirable that they continue to be available when the users are on the move, particularly at hotspots.
