Configuring Router A

destination number is 5000, the routing type is SIP, and the SIP routing method is proxy server.
3. Configure SIP registration in the connection properties configuration page: Enable SIP
registration, and configure the main registrar’s IP address as 2.1.1.2.

Verifying the configuration
• Select Voice Management > States and Statistics > Local Survival Service States from the
navigation tree. You can find that numbers 1000 and 5000 have been registered with the local
SIP server on Router C.
• Phones 1000 and 5000 can call each other through the local SIP server.
Configuring local SIP server to operate in alive mode
Network requirements
Router A and Router B carry out call services through the remote voice server VCX. Configure the
local SIP server on Router A to operate in alive mode, so that calls can be originated or received
through Router A when the VCX fails. When the VCX recovers, it will take over call services again.
