CHAPTER 3 EXPANSION STAGES AND SYSTEM CAPACITY
NOTE:
• To configure VoIP channels on the DSP chip of a DSP module, make sure the VoIP mode parameter
in the Media resources ( =ym) view is not set to No VoIP. The setting is valid for 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 mainboard 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 ).
• 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.
