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 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 (see also
"Standard Media Switch modes
of operation", page 47
).
– 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.

G.729 Codec
This licence allows the use of a G.729 codec for the voice channel of Aastra SIP
phones, IP system phones and SIP network interfaces (also for SIP networking).
The licence is also needed for the voice compression of voice mail audio data, if
the Enterprise voice mail system in expanded mode. The licences are always
used wherever they are required. Aastra SIP-DECT® and standard SIP terminals
do not require this licence. Likewise, calls to the emergency number do not re-
quire a licence.
