Notes
– To configure VoIP channels on the DSP chip of a DSP module, make
sure the ( =ym) VoIP mode parameter in the DSP configuration is not
set to No VoIP. With the exception of the IP media modules the config-
ured VoIP mode applies to all the DSP chips of a node. If 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. 16).
– 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.
