Most phone systems use the same standard star codes to control call forwarding. Below are the three most common types. Dial these from the line you want to forward, and use your ServiceForge number as the forwarding destination.
Standard Call Forwarding
Forwards every call immediately to your ServiceForge number.
Dial *72 (or 72#) from the line you want to forward.
Enter your 10-digit ServiceForge number.
To stop forwarding, dial *73 (or 73#) from the same line.
Busy Call Forwarding
Forwards calls only when your line is already busy.
Turn on: dial *90 (or 90#).
Turn off: dial *91 (or 91#).
No-Answer Call Forwarding
Forwards calls after a few rings when you don't pick up (usually 3–4 rings, or a number you specify).
Turn on: dial *92 (or 92#).
Turn off: dial *93 (or 93#).
