You must type the same primary and the inverse failover group domain names, which you have already set on the Session Manager Failover Group screen. For example, if you have set the Failover Group Domain names on the Session Manager Failover Group screen as SM1-SM2.company.com (primary domain name) and SM1-SM2-inverse. company.com (inverse domain name), must set the Failover Group Domain names on the Communication Manager Failover Group screen as the same.

If you are using the Avaya supported server, you can enter 1999 possible route patterns. You must set the same route pattern in the order you defined on the Session Manager Failover Group screen. For example, if you have set the SM2 as first Session Manager and SM1 as secondary Session Manager in the route pattern list, on the Communication Manager Failover Group screen, the route pattern must have the trunk group that is associated to SM2 listed first and the trunk for SM1 listed second.

You must set the Group Type field on the Trunk Group and the Signaling Group screens to sip and set the Peer Server field on the Signaling Group screen to SM for the referenced route number.
