Please refer product documentation:

For details, see Operation and Maintenance > Operation Guide > Valued-Added Service > PBX Group Line Selection Service in the U1980 product documentation.

User A picks up the phone and dials *11*TN# (TN: number of user B for which user A answers the call).

Run the following command to query the number of a call pickup group: show subscriber by pickupgroupno <0-499>

Method 1: Assume that the group pickup service has been activated for user A, and users A and B are in the same pickup group. 1. User C dials user B's number, and user B's phone rings. 2. User A picks up the phone and dials *11#. User B's phone stops ringing. 3. User A talks with user C. Method 2: When your phone screen displays a notification indicating an incoming call for a user in the pickup group, press the Pickup softkey. If multiple calls in the pickup group are available for pickup, your phone picks up the call that has been ringing for the longest time.
