If you have multiple customer premise extensions on your phone line this feature will let you call other extensions or transfer a call between them.

​How to use

  • Pick up an extension and dial your own phone number.
  • When you hear the busy tone, hang up. All the extensions will start ringing. Do not answer but wait for the other extension to pick up.
  • [When the other extension picks up, the extensions will stop ringing.
  • Pick up your extension and you will be connected to the other party. If no one answers on another extension, the extensions will stop ringing after a timeout period.
