Configuring VoIP survivability

Survivability features enable the 6400-S to extend the availability of VoIP services. These features include:

•Support for redundant SIP softswitches

•Support for the Virtual Router Redundancy Protocol (VRRP), allowing a backup 6400-S to take control for a master 6400-S in the event of a failure.

Configuring sofswitch survivability

If you will be using multiple SIP softswitches then you will need to enable server redundancy and specify the time between DNS lookups in the 6400-S. Enabling redundancy allows a DNS server to provide a list of multiple call processing servers to the 6400-S in the answers to SRV lookups. Each server in the list will be monitored using periodic messages by the 6400-S and the highest priority server that is currently reachable will be used for signaling. The 6400-S uses the reachability settings described below to determine the status of remote servers and remove inoperable servers from the list.

Triggers can also be used by the 6400-S appliance to determine when to forward call requests to a secondary server in the list. A trigger is set when a configured number of resends are received by the 6400-S from a SIP user agent attempting to place a call. When initiating a call a SIP user agent will send an INVITE message to the 6400-S that will then be forwarded to the primary server. In the event that the primary server fails before a reachability alarm has been declared using the heartbeat messages the user agent will resend INVITE messages until the trigger condition is met. At this point the 6400-S forwards the call request on to the secondary server in the list.
