Abstract
A mobile communication device encapsulates a fixed IP address based voice data packet (containing a fixed source IP address of the mobile communication device, a fixed destination IP address of a receiving device, and a voice data payload) into a sending network voice data packet (containing a sending network source IP address of the mobile communication device, a sending network destination IP address of an intermediate system, and the fixed IP address based voice data packet) and provides the sending network voice data packet over a first dynamic IP address based network to the intermediate system for decapsulating the fixed IP address based voice data packet from the sending network voice data packet, encapsulating the fixed IP address based voice data packet into a receiving network voice data packet and providing the receiving network voice data packet over a second dynamic IP address based network to the receiving device.
