5.1.17 DSP Resource Reservation

Description
A number of resources can be reserved for particular features or services to guarantee a minimum level of
service. Resources reserved for a particular service (e.g., conferencing) cannot be used for another service
(e.g., Unified Messaging).
For example, one may want to reserve resources for OGM (Outgoing Message) to ensure that recorded
messages can be played to incoming calls.
The resources can be reserved for the following types of services:
VoIP (G.711)
Conference CO line
Unified Messaging
Two-way Recording
OGM
Note
It is not necessary to reserve resources for a feature to use it. In normal operation, free DSP resources
are allocated on a first-come first-serve basis. Resources should be reserved only if a minimum level of
performance is required for your system.
For example, reserving resources for Two-way Recording (® 20.1.9 Unified Messaging—Automatic
Two-way Recording for Manager, ® 20.1.90 Unified Messaging—Two-way Record/Two-way Transfer)
also reserves UM ports. This can have the unintended effect of blocking access to the Unified Messaging
system even when no recording is being performed. Therefore, resources for Two-way Recording should
be reserved only if it is necessary to guarantee that Two-way Recording can be performed.
(® 20.1.2 UNIFIED MESSAGING FEATURES)
Resource Reservation Example
The following table shows the number and types of resources that must be reserved for a given workload. To
calculate the number of free (i.e., non-reserved) resources, a DSP M card (127 DSP resources) is assumed.
