ABSTRACT:
A network device having delayed call establishment is disclosed. The network device includes a port to allow the device to communicate with a called endpoint and a processor. The processor sends a call request message associated with a call to the called endpoint and receives a notification that a delay point has been reached. Alternatively, the network device includes a port to allow the device to communicate with a calling endpoint and a processor. The processor receives a call request message associated with a call from the calling endpoint, responds with a notification of delayed call establishment availability; and processes the call to a delay point. Once the delay point has been reached the processor determines if the call is to be established, and if the call is to be established, notify the called endpoint.
