An addressable call endpoint – a
software structure that binds a dialed digit string to a voice port or
IP address of the destination
gateway. Several dial peers always exist on each
router in the
network, and at least two dial peers will be involved in making a call across the network, one on the originating end and one on the terminating end. In Voice over IP, there are two kinds of dial peers:
POTS and
VoIP. VoIP peers point to specific VoIP devices.
