Expansion Stages and System Capacity
• VoIP Channels for Standard Media Switch
This licence enables the conversion of voice channels for VoIP-non VoIP connec-
tions and is used for IP terminals, SIP terminals, SIP access channels or to operate
an Aastra Intelligent Net. High voice data compression is possible with the
standard VoIP channels (G.729). One voice channel is activated with each li-
cence.
Notes:
– If the VoIP mode is set to G.711, two G.711 VoIP channels per system
can be used without a licence (see also
modes of operation", page
– Theoretically there are no VoIP channel licences in a pure VoIP envi-
ronment (only IP/SIP phones on the system and connection to the
public network via an SIP provider). However, 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
conversion of the voice data.
Aastra Intelligent Net
In an AIN the licence can also be used for the connections between the
nodes. Two VoIP channel licences are required for each node connec-
tion. 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 DSP resources on each node must be available
and allocated accordingly.
• Mobile Phone Extension
With this licence it is possible to integrate mobile phones into the communica-
tion system. One licence has to be purchased for each mobile phone.
Note:
The AMC User licence is also required on the mobile phone to enable
the easy integration of mobile phones with Aastra Mobile Client. This
licence can be purchased on the AMC licensing portal.
