The call forwardThe call forward (CF) feature when activated will route your call automatically to a number other than the number dialed. However,  two types of call forwarding are regional call forwarding, and call forwarding variable. Call forwarding is activated through using the CO number, or by dialing *72 or... no answer feature may be used with voice mail to answer your calls when you can’t. You can set this feature to forward after a predetermined number of rings (usually 3 or 4).  Sometimes LEC uses *92 to activate and *93 to deactivate.
