From the Device Management menu, SIP Proxy Server option, you can add a pre-configured
SIP Proxy Server to the Operations Console. You must configure the SIP Proxy server before
adding it to the Unified CVP Operations Console. Once added, you can add the SIP Proxy Server
to a device pool. You can also configure a link to the administration web page for the SIP Proxy
Server so that you can access that page from the Operations Console.

A SIP Proxy Server is a device that routes individual SIP transport messages among SIP
endpoints. It plays a key role in high availability in a Unified CVP deployment for call switching.
It is designed to support multiple SIP endpoints of various types, and implements load balancing
and failover among those endpoints. SIP Proxy Servers can be deployed alone or as a pair. Also,
smaller Unified CVP deployments can run without a SIP Proxy Server. In such cases, the Unified
CVP SIP service assumes some of those functions because it provides the ability to configure
a static table to look up destinations.
