This read-write Integer32, ranging 0 to 65535, sets the priority among MGC redundancy groups within the gateway, where a value of 0 means the group doesn't want gateway-initiated messages, a value of 1 is the highest preference, and higher numbers mean lower preference, with multiple groups allowed to share the same priority. An admin uses this to control which redundancy group the gateway favors when directing gateway-initiated signaling, useful when running multiple MGC groups for different services or failover tiers. Setting a backup redundancy group's priority to a high numeric value (low preference) ensures the primary group is favored under normal conditions.
