AT&T System 25 - Manual (Page 38)

Forwarding
You can have your personal calls sent to another telephone or to
an outside number. Unlike the Following feature, you do not
need to sign in your extension number at the other telephone.
Instead, simply forward your calls to another location while you
are still at your own telephone.
Read the information and procedures for both the Forwarding
and Following features. Then use the feature that best fits your
needs.
NOTE: Your System Administrator may or may not allow your
telephone to forward calls to outside telephone numbers. Check
with your System Administrator for any restrictions you may
have concerning this feature.
