Reserving audio channels
The allocation of audio channels between voice mail, Auto Attendant and call re-
cording is set under Reservation audio channels in the AMS Configuration Manager.
An audio channel for Auto Attendant is always used in cases where an incoming

signed an Auto Attendant profile. In all other cases one audio channel is used for
voice mail in connection with the voice mail system. Audio channels for call record-
ing are used exclusively for the manual or automatic recording of phone calls.
