Auto callback

This facility enables you to be called back automatically, either if the called extension is engaged, (you will be be called back when the handset is replaced) or if there is no reply (you will be called back when the extension is next used and the handset is replaced).

In both cases your extension will give one long ring and then you must pick up the handset within 15 seconds or the auto callback will be cancelled. Auto Callback will also be cancelled after a successful callback or at midnight. You may set up only one auto callback to other extensions but it is possible for several different extensions to set up auto callback on your extension.

To set up:

  • When hearing a ringing tone or engaged tone, dial R and listen for dial tone.
  • Dial #1, you should hear the assurance tone unless you already have an Auto Callback set or the extension you are calling is in Do Not Disturb mode.
  • Hang up.
  • When the handset of the called extension is next replaced your telephone will give one long ring.
  • Pick up your handset within 15 seconds or the callback will be cancelled. The extension you want will ring as for a normal internal call.

To cancel:

  • You will need to do this if you want to replace an auto callback number.
  • Pick up your handset and wait for dial tone.
  • Dial ##1 and wait for the assurance tone.
  • Hang up.
