To automatically make room for new call recordings
1 Limit the size of the placeholder user’s voice mailbox to the amount of disk space you want
to devote to call recordings. Use the formula 1 minute = .46MB. For example, to devote 1
GB to call recordings, set the user’s voice mailbox to 2185 minutes. See “Configuring the
user’s voice mailbox” on page 11-25.
2 Configure system call recording to automatically delete the oldest call recording when the
mailbox is full. See “Recording all calls” on page 19-9.
Allocating DSP resources for call recordings
Before beginning to record all calls, you should make sure that your system configuration
includes enough DSP resources to meet the increased demand. You allocate these resources via
the Resource Management applet, as described in “Using the Resource Management applet and
Resource Management Advisor” on page 23-44.
Important: If you upgraded to Wave ISM 2.0 from a previous version, see “About resource
reallocation of call recording resources after upgrading” on page 19-7 for important information
about your call recording resource allocation, including a manual resource allocation step that
you may be required to perform.
Wave’s scalable call recording uses different types of DSP resources, depending on the type of
call being recorded:
•
Recording a 2-party call. Two Call Record resources are used to support call recording on
a 2-party call. To allocate this type of resource via the Resource Management applet,
choose
Conference Resources > Ad-Hoc Conferencing > Ad-Hoc Participants.
The number of Call Record resources to allocate depends on the number of simultaneous
call recordings that Wave needs to support. In general, the number of Call Record
resources assigned should be double the maximum number of simultaneous calls that the
system needs to record. If a call comes in and resources are not available to record the call,
the call will proceed as normal but will not be recorded.
A typical application of call recording is to record all external calls and exclude internal
station-to-station calls. In this scenario, a good rule of thumb is to allocate double the
number of Call Record resources as there are working trunks on the system. For example,
allocating 20 Call Record resources will fully support recording all external calls for 10
trunks.
