Terminal Proxy Server

The Terminal Proxy Server (TPS) acts as a signaling gateway between the IP Phones and the Call Server using the UNIStim protocol. It performs the following functions:

converts the IP Phone UNIStim messages into messages the Call Server can interpret

allows IP Phones to access telephony features provided by the Call Server

The TPS also controls the IP Phone registration.

SIP/H.323 Signaling Gateways

SIP/H.323 Signaling Gateways are software components configured on virtual loops, similar to IP Phones. SIP/H.323 Signaling Gateways bridge existing call processing features and the IP network. They also enable access to the routing and features in the MCDN feature set.

Note 1: The SIP/H.323 Signaling Gateway must register with the Network Routing Service (NRS).

Note 2: Virtual TNs enable you to configure service data without hardwiring IP Phones to the CS 1000S system. Virtual TNs are configured in LD 97.

To support IP Peer Networking, dual Call Servers in a CS 1000S must be associated with Signaling Servers that run SIP/H.323 Signaling Gateway software. The number of Signaling Servers required depends on the capacity and level of redundancy required.

Network Routing Service

The NRS application provides network-based routing, combining the following into a single application:

H.323 Gatekeeper — The H.323 Gatekeeper provides central dialing plan management and routing for H.323-based endpoints and gateways.

SIP Redirect Server — The SIP Redirect Server provides central dialing plan management and routing for SIP-based endpoints and gateways.
