Remote Call Forwarding from Traditional Land Line
Once upon a time it was possible to call your home land line (while away), wait for your VM outgoing message to begin, enter your PIN and then remotely activate Call Forwarding. In other words, you left the house and forgot to forward your calls. Not talking about a U-Verse, Digital or VOIP home phone but the original AT & T land line.
If anyone knows how to do this, an answer would be greatly appreciated.
