Default Auto
Attendant
Extensions
Default extension that the NBX system assigns to the default
Auto Attendant. The Auto Discovery process assigns this
extension.
The system must direct each call coming in on an external line to
an extension. During the Auto Discovery of external lines
(analog lines and Digital Line Card channels), the NBX system
assigns the default extension (500) as the Auto Attendant
extension. After you import the dial plan configuration file and
complete the Auto Discovery process, you can manually
configure the extension for each analog line and each Digital
Line Card channel.
For both 3-digit and 4-digit dial plans:
■
Extension 500 is reserved as the default Auto Attendant.
■
Extension 501 is reserved as the voice mail Auto Attendant.
