Cisco 8851, Administration Manual

Description Parameter
If set to No, the fallback happens immediately and automatically. If the
Proxy Fallback Intvl is exceeded, all the new SIP messages go to the
primary proxy.
If set to Yes, the fallback happens only when current registration expires,
which means only a REGISTER message can trigger fallback.
For example, when the value for Register Expires is 3600 seconds and
Proxy Fallback Intvl is 600 seconds, the fallback is triggered 3600
seconds later and not 600 seconds later. When the value for Register
Expires is 600 seconds and Proxy Fallback Intvl is 1000 seconds, the
fallback is triggered at 1200 seconds. After successfully registering
back to primary server, all the SIP messages go to primary server.
