Abstract
A communications system includes a first switch and a second switch coupled to a packet-based network. A first set of network terminals are coupled to the first switch, and a second set of network terminals are coupled to the second switch. Each of the terminals is associated with a virtual terminal number (VTN). Each of the first and second switches store profile information associated with VTNs of the terminals. The profile information relate to the capabilities or features of the network terminals. The switches communicate signaling over a packet-based trunk, or virtual trunk, that is established on the packet-based network. Each switch sends messages to their associated terminals to establish media paths over the packet-based network to establish a call session.
