Local Number Forwarding Setup

Hello Guys,

First of all hi to everyone, i will really appreciate any help you can give me.

I am having problem configuring local number forwarding. All i know is it can be configured in extensions.conf inside asterisk folder, but i don’t know where is the exact location of the code that i can setup the local calls.

For example i want asterisk to forward a number when a user press 0 after the voice prompt, and where can i setup the number for dial 0 extension.
