The operating mode for the Media Switch is determined using the
VoIP mode
pa-
rameter: The VoIP hybrid mode handles both G.711 and G.729 for coding voice
data. Although more voice channels are available per DSP in
Only VoIP G.711
than in hybrid mode, the volume of voice data is greater and requires a greater
bandwidth. The configured mode is always valid for the entire node.

a licence. One

licence is required for
each additional VoIP channel.

FoIP
Reliable real-time fax transmissions via an IP network using the T.38 fax protocol
(ITU-T). FoIP channels can be used without a licence.

Voice mail
Voice messages and greetings need to be compressed before they are stored in
order to increase the voice memory capacity of the Basic Voice Mail System from
approx. 20 minutes to approx. 160 minutes. This requires an
Enterprise Voice Mail
licence and DSP resources. Two compressed Voice Mail channels are available
with the licence. Each additional Voice Mail channel requires an additional
Enter-
prise Voice Mail Channels
licence. With additional licences the voice memory ca-
pacity can be increased to a total of 400 minutes (
Additional Voice Mail Recording
Time
licence); the Auto Attendant function can then also be used (
Auto Attend-
ant
licence).
The operating mode for the Voice Mail System is determined using the
Voice
Mail mode
parameter: The
Normal (G.711 or G.729)
hybrid mode handles both
audio formats while the number of voice channels per node is restricted to 4. In
the
Expanded (G.729 only)
mode there are more voice channels available per
node than in hybrid mode. However the quality of the audio data is somewhat
poorer as a result of the compression. The configured mode is always valid for
the entire node.
•
GSM
Enhanced functionality is achieved for integrated GSM terminals by providing
special DTMF receivers during the call connection. Suffix dialling procedures
such as enquiry calls or setting up a conference can be carried out as a result.
The number of GSM channels – and therefore the number of DTMF receivers –
depends on the number of users with integrated GSM terminals who want to
use this functionality simultaneously. One
GSM Terminals
licence is required for
each integrated GSM terminal.
