Expansion Stages and System Capacity
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.
• G.729 Codec
This licence allows the use of a G.729 codec for the voice channel of Mitel SIP
phones, IP system phones and SIP network interfaces (also for SIP networking).
The licences are always used wherever they are required. Mitel SIP-DECT and
standard SIP terminals do not require this licence. Likewise, calls to the emergency
number do not require a licence.
Note
If several emergency destinations are defined in a system, the following points need to be
considered:
– Sufficient G.729 Codec licences must be available.
– No phone and no SIP network interface is configured exclusively to G.729 Codec.
Networking
• B-Channels on PRI Cards
Ten B-channels can be used without licences for each PRI interface. These chan-
nels cannot be transferred to other PRI interfaces. An additional channel is acti-
vated with each licence. These licences are in a pool and are used from any PRI in-
terface, if necessary (per call) .
Mitel Advanced Intelligent Network
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.
Mitel Advanced Intelligent Network
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.
• Lync Option for SIP Access Channels
This additional licence enables the use of a SIP access channel with Lync-specific
options and features. It is required for each channel in addition to a
Channels licence.
Private networking
• QSIG Networking Channels
These licences are used to implement a private leased-line network with QSIG by
