Use Call Pickup when you aren’t at the ringing phone you want to answer.
1. Hear the phone ringing that you want to answer
2. Dial 7 + extension number
Example: If extension 400 is ringing and the person wants to answer 400 without running over to pick up the handset press 7400 ‘Dial’ and you will intercept the call on the ringing phone from any other phone in the office.
