Call Pickup can be done within a group. Call Pickup is referred to as Ringing Number Pickup in CS 1000. Picking up a ringing number in another group is referred to as Group Pickup in CS 1000. Picking up a specific ringing destination is referred to as Directed Pickup, DN Pickup, or Directory Number Pickup in CS 1000.

All three have a corresponding Communication Manager equivalent, and the end user experience should have no noticeable differences beyond a potential of the group indices being changed.

Caveats exist around the CS 1000 Group Pickup migration to the Communication Manager Extended Pickup Group. The group sizes may differ. The groups allowed within a group pickup are dependent on the extended group, which is a supergroup enclosing the smaller groups.

The superset group can hold up to 25 groups. The group pickup can only pick up calls within the supergroup to which it belongs. As a result, the group indices may not map 1:1 from CS 1000 to Communication Manager and Device Adapter.
