Reserving audio channels
The allocation of audio channels between voice mail, auto attendant, call recording
and announcements is set in the general voice mail settings (
=u1
).
An audio channel is always used for Auto attendant when an incoming call triggers
greetings from mailboxes which are assigned an Auto Attendant profile. Audio chan-
nels of auto attendant are also used for queues with announcement. In all other cases
one audio channel is used for voice mail in connection with the voice mail system.
Audio channels for call recording are used exclusively for the manual or automatic re-
cording of phone calls.
Audio channels for announcements are used if the announcements have audio files.
No audio channels are required for normal announcements by phone.
If no audio channel is reserved for any of the functions described above, or if all re-
served audio channels are already used, audio channels from the
Non-re-
served/shared
pool are used.
No audio channels can be reserved for conference bridges. Audio channels from the
Non-reserved/shared
pool are always used for the conference bridge.
Announcement service and music on hold use their own resources.
