The media gateway may be requesting service from a survivable core server after the media gateway loses communication with the main (primary) server. The interval from the loss of communication to the time the media gateway requests service of a survivable core server is called the primary search time out interval. During this interval the media gateway only tries to reconnect to the primary server. The value for the primary search timer is administrable from 1 to 59 minutes, with a default 1 minute. For more information on the primary search timer see, Administering Avaya Aura® Communication Manager.
