OAMP considerations for the Announcements service

For this service, the additional INFO messages sent to the Session
Manager have some impact on the Session Manager as well as Media
Application Server performance. The Session Manager must process the
incoming INFO messages. Also the billing service on the Session Manager
must generate the IPDRs based on the information received in the INFO
messages.
OAMP considerations for the Announcements service
The Announcements service handles treatment or causes and branding for
an MCS system. The effect of OAMP, as they relate to the Announcements
service and the whole system, need to be evaluated. IPDR records are used
to store accounting information for announcements. When a MAS-based
application indicates that it cannot find a file or folder requested for playback
by the Session Manager, the Session Manager creates a log file.
The Media Controller operational measurement (OM) (annc::An-
nouncementServicesUses) is increments each time a treatment or
branding announcement plays. This counter keeps track of how many
announcements were played over a certain period of time.
When provisioning audio files for Media Application Server services, both
on the Media Application Servers and the Provisioning Module, you must
use the correct audio file names and take care to avoid typing mistakes.
No automatic check for file name validity exists; therefore the domain
administrator must check the file names manually. Audio files should
have the same name across all servers in a common resource pool. The
administrator must ensure that each server in a resource pool contains a
copy of each audio file.
