ABSTRACT:
A network device is disclosed. The network device has a port to allow reception of an incoming call at a first endpoint and a memory to store endpoint identifiers and associated capability information. A processor in the network device is to determine an identifier for a second endpoint from the incoming call, access associated capability information for the second endpoint, if it exists, set a first field value depending upon any associated capability information available, transmit a message including a first field value and then perform a capabilities exchange with the second endpoint, if necessary, depending upon the first field value and a second field value received from the other endpoint.
