Redundant mediation server RRS feed

  • Question

  • We currently have an ods 2007 RTM environment with a single Mediation server
    routing to a Cisco Call Manager.
    Can I make thie OCS / CM connection highly available? Configure a second
    mediation server that will either share the calls, in a load balanced
    method, or be there as a warm backup should the first mediation server fail?
     
    Would (or could) a harddwarea load balancer be used in this configuration?

  • Yes you can configure a second mediation server to point to another or the same CUCM subscriber.You can either load balance or alternate route to the second mediation server, just depends on what you feel is the best option.

    You could use a HLB but it would not be supported and is not required for this configuration.

  • In addition, OCS has the ability to have multiple routes associated to a Dial Plan so if the first 'route' does not repsond it will cycle to the second. This does not offer load balancing, but it does offer HA.

  • Brian,

    This is called alternate routing in telecom speak.

  • The only issue with the multiple routes method is that outbound calls will attempt to use the primary route for 15-30 seconds before it times out and switches to the second route.  Once you realize the first route is down, you can disable it in Route Helper, which will speed up call routing until you get the primary server back up and going.
