Automatic Callback - If you call someone and their line is busy, you can
dial *66 and your phone will continue re-dialing until the call goes through.
Once their line is open, your phone rings to alert you. When you pick up
your phone, the call is completed.
Automatic Recall - If you missed a call, you can dial *69 and find out the
number of the call you just missed. If the call is local, you can tell the
system to dial the number for you. If it's not a local call, you will have to
dial the number yourself. Cell numbers are not local calls.
These Calling Features are already on your line, you can use them any time.
