Internet Telephone Terminal Proxy Server
The Terminal Proxy Server (TPS) provides the signaling interface for the
Internet Telephones. The TPS supports a maximum of 10,000 Internet
Telephones on each Succession Signaling Server. In conjunction with the
Succession Call Server, the TPS delivers a full suite of telephone features.
The Unified Network IP Stimulus protocol (UNIStim) is the single point of
contact between the various server components and the Internet Telephone.
UNIStim is the stimulus-based protocol used for communication between an
Internet Telephone and a Terminal Proxy Server on the Voice Gateway
Media Card.
IP Peer Networking supports the i2002 and i2004 Internet Telephones and the
i2050 Software Phone (soft client) for IP Telephony. Each Internet
Telephone can be configured through the Dynamic Host Configuration
Protocol (DHCP) to register with a Succession Call Server for feature control.
The TPS on the Succession Signaling Server also manages the firmware for
the Internet Telephones which are registered to it. Accordingly, the TPS also
manages the updating of the firmware for those Internet Telephones. For

procedures that provide multimedia communication services over packet

The H.323 Signaling software (Virtual Trunk) provides the industry-standard
H.323 signaling interface to H.323 Gateways. This software uses a
