1602-07: Repeat Redial Busy Timer [System: Timers: Features: Outgoing (1602): Repeat Busy]

Use this option to set how long the system waits for busy tone when processing an Auto Redial callout attempt. The interval is measured from the last digit dialed to the receipt of busy tone. If the system doesn’t receive busy tone within this interval, it assumes that the call went through and cancels Auto Redial.
