For example, on Grandstream IP phones, you can enable redirection by the functions of the phone itself, but if the phone is far away and there is no way to do it on it, but it is possible to log in using the SIP number of this phone, then to activate call forwarding, you can make a voice menu when dialing a certain number, for example, *21 to activate call forwarding and enter the phone number to which calls will be forwarded, and *22 to cancel call forwarding.

I will give an example of a quick installation of Asterisk on Ubuntu Server.
I will install it on versions 14.04 LTS and 16.04 LTS.
