Abstract:
A dual mode user terminal for a calling party can make calls over both a conventional cellular network and a packet data network using VoIP protocols. If the called party is not available to receive a VoIP call over the packet data network, the user terminal for the calling party can request a third party user terminal available on the packet data network to relay the call between the calling party and the called party.
