SIP Proxy

SIP Proxy provides an interface for SIP communication between SIP devices and SIP Server components. It handles register requests, load-balances SIP transactions, and provides an alternative HA model that supports deploying primary/backup SIP Server instances within the same HA pair across different subnets and does not require a virtual IP address.

See the Configuring SIP Proxy section for specific configuration information for the SIP Cluster environment.
