Step 5 - Configure call processing server redundancy

If you will be using multiple network based call processing servers then you will need to enable server redundancy and specify the time between DNS lookups in the V2IU appliance. Enabling redundancy allows a DNS server to provide a list of multiple call processing servers to the V2IU appliance in the answers to SRV lookups. Each server in the list will be monitored using periodic messages by the V2IU appliance and the highest priority server that is currently reachable will be used for signaling. The V2IU appliance uses the reachability settings described in step 2 to determine the status of remote servers and remove inoperable servers from the list.

Triggers can also be used by the V2IU 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 V2IU appliance 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 V2IU appliance 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 V2IU appliance will forward the call request on to the secondary server in the list. Please use the following steps to enable redundancy and set triggers:

1.Log into the V2IU appliance using a Netscape or Internet Explorer web browser.

2.Select System.

3.Select Survivability.

4.Enter the Time between DNS lookups (in seconds) in the Softswitch Reachability section of the web page.

5.Select Enable SIP server redundancy in the Softswitch Redundancy Settings section of the web page.
