Deployment and Operation Notes12General• In an network environment where more than one Call Pilot isinstalled, an Application Gateway is required for each Call Pilot.• The Voice Office Application Suite does not support operation withNortel Virtual Office.• To support the creation of an IP/DN map, the Application Gatewaymust be on the same LAN segment as the call server. The ApplicationGateway must communicate with the call server via its EmbeddedLAN (ELAN) to retrieve information for the IP/DN map.• (517) For sites using Nortel Communication Server, the informationfor the IP/DN map can be obtained from the signaling and callservers. For sites using Communication Server 1000, release 4.0, youconfigure a connection between the Application Gateway and onesignaling server, which provides the Application Gateway withinformation from all connected call servers. For sites using twosignaling servers with Communication Server 1000, release 4.5, youmust configure a connection between the Application Gateway andboth signaling servers. If communication with signaling servers failsor signaling servers are taken offline, the Application Gatewayoperation may be impacted until the Application Gateway canresynchronize with the signaling server.• The Application Gateway does not support multiple appearance DNs,that is, more than one phone with the same primary DN. If more thanone phone has the same primary extension, only one of those phones,the one most recently registered with the Application Gateway, willreceive a page or broadcast.Workaround: Assign a unique primary DN to each phone and use thesecondary extension for assigning multiple sets the same DN. Forexample, if you have two phones with primary extension 100, changethe primary extension of one of those phones to a unique number andalso assign that phone a secondary extension of 100.• (653) The Volume key does not work in XAS mode.• (757) Express Directory is the only Voice Office application that can beused with phones that are behind a Network Address Translation(NAT) device. The Application Gateway can also deliver transformedcontent to phones that are behind a NAT device.• Because the Application Gateway must synchronize with otherservers to obtain information such as phone DN and IP address, anextension might be temporarily unable to access a Voice Office
