NOTE
To be able to configure VoIP channels on the mainboard's DSP, make sure that in the Media resources (
=ym) view the VoIP mode parameter is set to G.711.
The configured VoIP mode is valid for all the DSP chips of a node. The following also applies to this
mode:
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 voice mail channels are configured and licensed, the two G.711 basic voice mail channels that can be
used without a licence are redundant (see ).
The system has to be restarted for the configuration changes of the DSP to take effect.
Expansion with cards and modules
A basic system can be individually expanded using interface cards and system modules. The number and
position of the available slots are described in the chapter
System modules
With system modules a distinction is made between modules expandable as an option (DSP modules)
and mandatory modules (CPU module, RAM module). This chapter describes only the system modules
that can be expanded as an option. They expand the resources of the communications server, which
means the system can be expanded step by step in line with requirements.
