♦ 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.
