Unforwarding calls?

Question

I'm confused, What is the cause of unforwarding calls? What does it do? And also does anything happen if you dial an "11" on your home phone?

Answer 1

Call forwarding is just a feature. You dial *72 to activate, and to deactivate or "unforward" you dial *73.

I dont know about the 11.  Try it and see. Nothing happens im sure

Answer 2

As for call forwarding and many other features, especially for those with an old 'dial' phone, you can replace the 'star' symbol (*) with 11.. For instance for call forwarding, you could use *72 or 1172.. For *67, you could use 1167.
