Claim Text:
1. A computer-implemented method having a programmable processor and memory coupled to a communications network, the method comprising: receiving, by a signaling server from a host server, a command containing a group field and network interface unit identification (NIU id); transmitting, by the signaling server, a select port command to a media server based on the NIU id; receiving, by the signaling server from the media server, an acknowledgement of port selection; transmitting, by the signaling server, a command to a remote endpoint where a session initiated protocol (SIP) call is executed; receiving, by the signaling server from the remote endpoint, a command indicating that the SIP call has been answered by the remote endpoint; transmitting, by the signaling server to the media server, a start port command based on the select port command; receiving, by the signaling server from the media server, an acknowledgement of the start port command; establishing a real-time transport protocol (RTP) session stream between the media server and the remote endpoint using the selected port; receiving, by the signaling server from the media server, a second port selection; transmitting, by the signaling server to the media server, a second start port command; and receiving, by the signaling server from the media server, a second acknowledgment; wherein the acknowledgement of the start port command is failure and the call is no longer active.
