Supplemental Services.
♦ Additional Call Offering (ACO) is required on your ISDN line in order to use
the Call Waiting feature. Flexible Calling is required on your ISDN line in
order to use the Three-Way-Calling or Call Transfer features. You need to
check with your telephone company to confirm if these services are available
to you and if so, are there any additional charges for them.
♦ In some cases, your telephone company may only enable these features on
your first directory (phone) number. In this case, you may want to request
that the features be enabled on your second directory number as well.
