Call forward + pickup group call

I have a few question concerning basic telephone functions.

How do i configure the following: (or where do i find more info)

  • user can forward his calls to someone else
    (so whenever someone calls the users extensions he’s directly forwarded to the other one)

  • if someone calls a user from the group someone else who is configured in the same group can pickup that line via.

Ik hope you understand my needs. (my english is not perfect)

Call Forward … forwarding

Pickup Group … ckupgroups
