Feature codes are simple ways to access common features on a phone system. You simply dial the feature code to access that particular dial-plan feature, for example *72 would be to enable call forwarding.
These codes are powerful short-cuts to access features inside your phone system without having to use a Web browser to access the feature in your account or having to contact your phone service provider. Even landline phone service will have most of these basic feature codesand if you have VoIP service it will usually have a much more extensive set of feature codes, though be aware these often vary between each VoIP provider.
In this guide we will detail the most common feature codes and then highlight some more advanced dial-plan feature codes found in some other phone systems.
