Conditions
• One conference call supports a maximum of 8 parties.

-IP extensions (e.g., DPTs or SLTs) and when the conference call is
made on non-IP trunks (e.g., analogue, ISDN), a DSP card is not required.
• The maximum number of parties that can be engaged in conference calls simultaneously is 32 parties (or
96 parties when a DSP card is installed).
• It is possible to select which of the following devices to use when making a conference.
– PBX MPR
– Optional DSP card
Better sound quality can be achieved by selecting the optional DSP rather than the PBX MPR. However,
in this case DSP resources will be used.
• DSP Resource Usage
A conference call requires a certain number of DSP resources. If all DSP resources are in use, this
operation cannot be performed. To ensure a minimum level of performance, DSP resources can be
reserved for conference calls. (® 5.5.4 DSP Resource Usage)
