General
•In an network environment where more than one Call Pilot is
installed, an Application Gateway is required for each Call Pilot.
•The Voice Office Application Suite does not support operation with
Nortel Virtual Office.
•To support the creation of an IP/DN map, the Application Gateway
must be on the same LAN segment as the call server. The Application
Gateway must communicate with the call server via its Embedded
LAN (ELAN) to retrieve information for the IP/DN map.
•(517) For sites using Nortel Communication Server, the information
for the IP/DN map can be obtained from the signaling and call
servers. For sites using Communication Server 1000, release 4.0, you
configure a connection between the Application Gateway and one
signaling server, which provides the Application Gateway with
information from all connected call servers. For sites using two
signaling servers with Communication Server 1000, release 4.5, you
must configure a connection between the Application Gateway and
both signaling servers. If communication with signaling servers fails
or signaling servers are taken offline, the Application Gateway
operation may be impacted until the Application Gateway can
resynchronize 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 than
one phone has the same primary extension, only one of those phones,
the one most recently registered with the Application Gateway, will
receive a page or broadcast.
Workaround: Assign a unique primary DN to each phone and use the
secondary extension for assigning multiple sets the same DN. For
example, if you have two phones with primary extension 100, change
the primary extension of one of those phones to a unique number and
also 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 be
used with phones that are behind a Network Address Translation
(NAT) device. The Application Gateway can also deliver transformed
content to phones that are behind a NAT device.
•Because the Application Gateway must synchronize with other
servers to obtain information such as phone DN and IP address, an
extension might be temporarily unable to access a Voice Office
