Verifying the configuration
• When the VCX fails, the local SIP server on Router A starts to accept registrations from phones,
which then can call each other through Router A. 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 A.
• When the VCX recovers, Router A disables the local SIP server, and the phones register with the
VCX again.
