Deployment and Operation Notes
18 Release Notes
Nortel Business Communication Manager (BCM) is not currently
•
supported for use with the Application Gateway. In the Operation >
Voice Office > Voicemail page of the Administration Tool, the BCM
Nortel Messaging option for the Unified Messaging Type field is for
future use.
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 IP phones, signaling server,
and call server. The Application Gateway must communicate with the
call server via the call server's Embedded LAN (ELAN) to retrieve
information for the IP/DN map.
(517) For 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 4.0, 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.
