Changing the rings-to-answer setting
When the answer mode is set to Automatic, the device rings-to-answer setting determines
the number of times the telephone rings before the device answers an incoming call.
If the device is connected to a line that receives both fax and voice calls (a shared line) and
that also uses an answering machine, you might need to adjust the rings-to-answer setting.
The number of rings-to-answer for the device must be greater than the rings-to-answer on
the answering machine. This allows the answering machine to answer the incoming call and
record a message if it is a voice call. When the answering machine answers the call, the
device listens to the call and automatically answers it if it detects fax tones.
The default setting for rings-to-answer is five for the U.S. and Canada, and two for other
countries/regions.
