Accessing the Unified Messaging system (including recording calls)
For SIP extension calls, the number of required resources differs depending on the codec (G.711 or G.729)
used.
Examples of DSP resource usage
Fundamentally, the number of resources required for a given situation is the sum of the resources required
for each individual operation. The following examples illustrate DSP resource usage in various situations.
[Unified Messaging access]
Extension
Y
X
G.711
UM
Control Box
Playing back messages from or recording messages to the Unified Messaging (UM in the figure above)
system requires DSP resources, X in this example, in addition to the resources required for the G.711 codec
(Y). The total cost is X + Y.
DSP usage graph
The Control Box 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.
