an Mitel Advanced Intelligent Network. High voice data compression is possible with
the G.729 VoIP channels. An additional voice channel is activated with each licence.
Notes:
– If VoIP mode is set to G.711, two G.711 VoIP channels per system can be used without a
licence.
– Theoretically there are no VoIP channel licences in a pure VoIP environment (only IP/SIP
phones on the system and connection to the public network via an SIP provider). How-
ever, as soon as voice mail functions, the announcement service or music on hold is
used, VoIP channel licences are required as the use of these functions entails a conver-
sion of the voice data.

In an AIN the licence can also be used for the connections between the nodes. Two VoIP
channel licences are required for each node connection. The licences are always acquired
for the Master. The number of licences determines the maximum number of simultaneously
active conversions, regardless of the nodes on which they are currently being used.
Requirement: The media resources on each node must be available and allocated accord-
ingly.
If Virtual Appliance is used as Master, the VoIP channels of the master node are made avail-
able without a licence from the integrated Mitel Media Server. However, for the satellites'
VoIP channels, the licences must be purchased.

B-Channels on PRI Cards
10 B-channels can be used without licences for each PRI interface. These channels
cannot be transferred to other PRI interfaces. An additional channel is activated with
each licence. These licences are in a pool and are used from any PRI interface, if
necessary (per call).

In an AIN the licence is always acquired on the Master. For each licence an additional B
channel is available on a PRI interface of any node, depending on where the B channel is
currently being used.

SIP Access Channels
The connection of the system to a SIP service provider or the networking of the sys-
tems via SIP requires one licence per channel.

In an AIN all the SIP licences are always acquired for the Master. The number of licences
determines the maximum number of simultaneously active voice channels, regardless of the
nodes on which they are currently being used. Requirement: The media resources on each
node must be available and allocated accordingly.

These licences are used to implement a private leased-line network with QSIG by ena-
