A conference requires additional resources, Y, for handling the multiple voice channels. Also, in standard
two-way conversations, analogue lines generally do not require any DSP resources, but in a conference they
do. In addition, IP trunks in a conference require additional DSP resources.
For this example, then, the number of required resources is X + X + X + X + Y + Z + W.
DSP usage graph
The PBX keeps a record of the maximum DSP usage per hour for each of the following features/services. A
graph can then be displayed in Web Maintenance Console showing trends in DSP usage over time, as well
as the number of calls and operations that could not be performed due to lack of resources.
•
VoIP (IP trunk, IP extension and IP-CS usage)
•
Conference
•
Unified Messaging
•
OGM
•
Two-way Recording
The graph also shows the amount of free resources and the total resource use.
DSP resources can be reserved for and, therefore, guaranteed to be available for each service. For details
about reserving DSP resources, see 5.5.4.1 DSP Resource Reservation. If the DSP resources reserved for
a service are all used, free (unreserved) DSP resources can be used. The DSP resource usage graph shows
the DSP resources reserved for each service, the free DSP resources, and the total DSP resources available
on a per-hour basis. An example of the DSP resource usage graph is shown below.
