Call forwarding on AT&T.
To forward every call on an AT&T mobile, dial *21*, then the 10-digit number, then #, and press Call. Dial #21# to cancel. Wait at least three seconds for the confirmation tone before hanging up. For busy, unanswered or unreachable calls only, use your phone's call forwarding settings, which AT&T's device guides show on many phones.

For a business line
Forwarding missed calls to an answering service
Most businesses want calls they miss to move on, not every call. Set that in the phone's call forwarding settings for unanswered calls, which AT&T's device guides show on many phones, then call your number from another phone and let it ring out to check.
Forwarding only moves the call. If nobody answers at the other end either, the caller still hangs up. Our after-hours answering service guide covers what should pick up.
