There are two types of Ring Back:

  • Ring Back When Free sets up a call to a Featureline extension or external number that is engaged, as soon as it is free.
  • Ring Back When Next Used attempts to call a Featureline extension that hasn't been answered after it's next used.

Notes:

Ring Back When Free is not available for some types of phone number, for example, ISDN, DDI and international numbers.

If Call Diversion has been enabled on the internal extension you are ringing, Ring Back will be enabled against the extension to which the calls are diverted.

The Ring Back service is not available on lines in a Hunt Group.

Ring Back will not operate if the extension you are calling has Call Diversion activated to an external number.

To switch on Ring Back:

  1. Dial the extension or the external telephone number you require.
  2. Press the RECALL button.
  3. Wait for the dial tone.
  4. Dial *37#.
