  | Service Mode | • Board Hunting – In this mode, the MCU is | 
  | (cont.) | registered with the gatekeeper using the Network  | 
  | 
  | Service prefix. In addition, all the IP cards that  | 
  | 
  | are defined in the same Network Service register  | 
  | 
  | with the gatekeeper with the same prefix.  | 
  | 
  | When using the Network Service Prefix for  | 
  | 
  | dialing, the IP call that reaches the gatekeeper is  | 
  | 
  | forwarded to first available IP card on the MCU  | 
  | 
  | according to the cards registered with the  | 
  | 
  | gatekeeper for the Network Service whose prefix  | 
  | 
  | was used. In this mode, the dialed string must  | 
  | 
  | begin with the IP Service prefix and can be  | 
  | 
  | followed by the conference Numeric ID. For  | 
  | 
  | example: [H.323 prefix] [Conference/Meeting  | 
  | 
  | Room numeric ID/name].  | 
  | 
  | In a gateway call, the prefix can be followed by a  | 
  | 
  | Gateway Session Profile or by another format  | 
  | 
  | that can be read by the gateway:  | 
  | 
  | [H.323 prefix] [gateway service prefix] [gateway  | 
  | 
  | delimiter] [gateway information]  | 
  | 
  | Notes:  | 
  | 
  | • This mode is dependent on the gatekeeper’s  | 
  | 
  | implementation as the gatekeeper may not  | 
  | 
  | allow multiple registrations from different IP  | 
  | 
  | addresses.  | 
  | 
  | • Board Hunting is the default mode. It is not  | 
  | 
  | recommended to use Board Hunting with  | 
  | 
  | Forwarding. If both are selected, Forwarding  | 
  | 
  | overrides Board Hunting settings.  | 
  | 
  | • Register as a Gateway – Select this mode when  | 
  | 
  | using a Cisco gatekeeper.  | 
  | 
  | In this mode the gatekeeper is defined as a  | 
  | 
  | gateway. A gateway prefix is usually manually  | 
  | 
  | registered with the gatekeeper and the IP cards  | 
  | 
  | use the same prefix to register with the gateway.  | 
  | 
  | With a Cisco gatekeeper that supports this  | 
  | 
  | mode, the MCU is registered as an  | 
  | 
  | |
  | 
  | to start with the prefix as with Board Hunting.  |
