Positioning
Applications range from small offices and branches to small and medium-sized compa-
nies. Up to 200 users can be operated on the communication server. One licence is re-
quired for each user.
The diagram below shows the MiVoice Office 400 communication servers with their ex-
pansion capacity for users with SIP/IP phones and TDM extensions (FXS, DSI, BRI-S).

Networking Possibilities
MiVoice Office 400 communication servers at different company locations, even be-
yond national borders, can be linked together to form an enterprise-wide private com-
munication network with a common numbering plan. The following networking types
are possible:
Mitel Advanced Intelligent Network (AIN)
In an AIN several communication servers of the MiVoice Office 400 series can be con-
nected up to form a homogeneous communication system. The single systems are
connected with one another via the IP network, thereby forming the nodes of the over-
all AIN system One node acts as the Master and controls the other (satellite) nodes. All
the features are then available at all the nodes.
No call charges are incurred as the internal voice traffic between locations is routed via
the system’s own data network. All the AIN nodes are configured and set up centrally
via the Master.
If a node is isolated from the rest of the AIN by an interruption in the IP connection, it
restarts with an emergency configuration after a set amount of time. The connections
are then routed to the public network via local links, for example with ISDN or SIP con-
nections, until contact with the AIN is restored.
