Sending a fax by dialing from an extension telephone
Occasionally, you might want to dial a fax number from an extension telephone that is connected to
the same line as the all-in-one. For example, if you are sending a fax to a person whose device is in
the manual receive mode, you can precede the fax with a voice call to let that person know that the
fax is coming.
