Feature prefixes allow you to modify the behaviour of the call by adding a prefix to the called number. The system interprets the prefix, then strips it off before routing the call.

To add a new feature prefix

1. Log in to the Enswitch web interface.
2. Go to Features » Feature prefixes.
3. Click the "New" button.
4. Enter the following:
   • The prefix to match.
   • Optionally a description.
   • The purpose of the feature prefix. See below for details.
   • If you are logged in as a system owner, whether the feature prefix may be used by all customers on the system.
5. Click the "Save" button.

The following purposes are defined:

• Hide callerid. Use this to prevent your callerid being sent.
• Mailbox. Dial the prefix followed by a mailbox number to directly call that mailbox. This is useful for transferring external callers if you know the person you wish to transfer them to is unavailable.
• Set call forwarding. Dial the prefix followed by a number to set call forwarding to that number for the telephone line you are calling from.
