Configuring Avaya Aura™ Communication
Manager
General usage and Important Notes
For releases before Avaya Aura™ Communication Manager (Communication Manager) 6.0 the
special application SA8567- PHS X-Station Mobility over IP is mandatory to be installed to
enable the IP-DECT capability on Communication Manager. Since Communication Manager
6.0 IP DECT is part of the general Communication Manager features, hence SA8567 is not
available any more.
The communication between the Communication Manager and the IP-DECT system is done via
IP-Trunks using the H.323/X-Mobile protocol. One or more fixed IP trunk connections are
required between an IPBS Master and Communication Manager. The Radio IPBS are
controlled by the IPBS Master, they do not register to the Communication Manager system.
Several Master IPBS can be connected to the Communication Manager building one common
IP-DECT system while one main Master IPBS holds the DECT user database. Users can roam
between these IP-DECT masters using one single subscription with the system.
A separate IPBS Master needs to be configured for a site which has survivability for the
Communication Manager system. The primary trunks of this IPBS master will be configured to
the Communication Manager in the main location. Redundant trunks will be configured to the
local LSP that will take over if the connection to the main location fails. This LSP can only take
over if the main location uses PE (processor ethernet) for the trunk connection to the Master
IPBS (This requires Communication Manager 5.2 or higher).
For DECT R4 users the same features are available as for DECT R2 and previous IP DECT
users. The available features and feature operation is the same as for analog station users, but
interactions with Multiple Locations feature set is limited. Roaming users have to follow the
actual location rules for dialing and for feature activation/deactivation.
