Notes
– To configure VoIP channels on the DSP chip of a DSP module, make
sure the VoIP mode parameter is not configured to No VoIP. With the
exception of the IP media modules the configured VoIP mode applies
to all the DSP chips of a node. If the VoIP mode is set to G.711, two
G.711 VoIP channels per system can be used without a licence. The
G.711 VoIP channels of the configurable DSP chip on processor card
CPU1 can be combined with G.711 VoIP channels of DSP modules.
– If audio channels are configured and licensed, the two basic audio
channels that can be used without a licence are redundant (see
Tab. 14).
– Audio channels and FoIP channels can only be configured on one DSP
chip per node.
– The system has to be restarted for the configuration changes of the
DSP to take effect.
– After a first start all the DSP chips are configured on DECT.
[5...8] Depends on the parameter VoIP mode:
• G.711: 8 channels
• Secure G.711: 7 channels
• G.711/G.729: 6 channels
• Secure G.711/G.729: 5 channels
