Return busy tone when 
device is in use

Returns a busy tone to the caller if the telephone 
attached to this ATC port or ATA is in use.

■

If you enable this check box and the user enables the 
Do Not Disturb feature on the analog telephone, 
callers hear a busy tone whether or not the telephone 
is in use.

■

If you enable this check box and configure an Analog 
Line Card port such that the ATA is the auto 
extension, when an external call arrives on the Analog 
Line Card port and rings directly on the ATA, the 
caller hears Ring No Answer instead of a busy tone. 
This is the way that the NBX system works; it cannot 
seize the Analog Line Card port until the ringing 
telephone is answered.
