  • Utilization of media capabilities in a mixed environment
    Patent number: 8171146
    Abstract: 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.
