An apparatus and method for negotiating media capabilities is described. The method may comprise receiving an invite to establish a connection between a caller endpoint device and one of a plurality of callee endpoint devices of a shared line and identifying an initial common media capability between the caller endpoint device and the plurality of endpoint devices. Thereafter, the method may comprise negotiating a connection between the caller endpoint device and the callee endpoint device using the common media capability and determining if the caller endpoint device and the callee endpoint device have a common enhanced media capabilities. The connection may be re-negotiated using the enhanced media capability.

Utilization of media capabilities in a mixed environment

A network device with a configurable interface. The device has at least two communication ports. An interface in communication with the ports is configurable as to the network layer, or layerand, and the physical layer, or layer. The interface includes at least two lines for transmitting data and two lines for receiving data and a processor that determines the data transmitted and received.
