Auto Redial periodically redials a busy outside number. If a keyset user places an outside call and
the call recipient is busy, the user can press a soft key to enable Auto Redial. The keyset user
doesn’t have to retry the number, hoping it will go through.
Auto Redial will periodically retry the number up to 15 times. Auto Redial cancels when the called
party rings or answers, or when the extension:
- Places or answers another outside call.
- Receives an Intercom voice announcement or answers an Intercom call by lifting the handset
or pressing SPEAKER.
- Presses SPEAKER to cancel Auto Redial.
- Presses any other fixed feature key except MIC.
- Lifts and replaces the handset.
- Presses the CANCEL soft key (Super Display only).
For your reference, the following table shows the standard call progress tones.
