Standard SIP Terminals
One licence is required per terminal to operate standard SIP terminals. The li-
cences are needed when registering the terminals on the system and can be
used even if
Aastra SIP Terminals
icences are missing.
•
Video Terminals
In addition to the
Standard SIP Terminals
licence you need to purchase also an
Video Terminals
licence in order to use the video functionality of an standard SIP
video terminal. Use is also possible if
Aastra Video Terminals
licences are missing.
•
SIP Access Channels
The connection of the system to a SIP service provider or the networking of the
systems via SIP requires one licence per channel.
Aastra Intelligent Net
In an AIN all the SIP licences are always acquired for the Master. The
number of licences determines the maximum number of simultane-
ously active voice channels, regardless of the nodes on which they are
currently being used. Requirement: The DSP resources on each node
must be available and allocated accordingly.
•
VoIP Channels for Standard Media Switch
This licence enables the conversion of voice channels for VoIP - non VoIP con-
nections and is used for IP terminals, SIP terminals, SIP access channels or to op-
erate 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.
Note:
Theoretically there are no VoIP channel licences in a pure VoIP environ-
ment (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.
