Short codes are numbers that you can dial to enable and disable various features. The following are default short codes that may be available. However, your system administrator can remove and change the short codes available to you or all users. To use a short code, you may have to put your currently call on hold.
These are useful as they can be dialed from any phone on the system. For example, this allows you to login at a basic analog extension and still control a number of features.
Some short codes require you to enter some information when you dial them, typically an extension number. That is indicated by N in the short codes shown below.
For a list of other common dialing short codes, see Short Codes.
