Survivability
The survivability feature will allow the SIP User Agent to register with a
backup SIP Proxy which will be used to make and receive calls when the
primary SIP Proxy fails or is not reachable due to a network failure.
The prime reason for this feature is to maintain basic call functionality
when network failures occur and it is therefore expected that some fea-
tures and functionality will not be available when working in a survivability
mode.
