# Restrict Line Group Access

This procedure describes how to restrict line group access in a variety of ways. Select those methods that are appropriate for your server and users.

## Require Callers to Enter a Line Group Access Code

1. Customize an FCOS to include feature bit 160 (Caller must enter line group access code).

2. Set the Access Code in the Administrator’s Mailbox for each line group that requires an access code. The Department Code is the line group access code. Callers do not have to enter an access code on line groups with no department code in the Administrator’s Mailbox.

## Deny Login on Specific Line Groups

- Customize each FCOS to include feature bit 101-109 (Deny login on line groups 1-9, respectively).

## Force the Termination or Transfer of Calls to Greeting-only Mailboxes

1. Customize an FCOS to include one of the following feature bits:

   - 62 (Hang up immediately after greeting)

   - 63 (Call mailbox attendant after greeting)

   - 64 (Call mailbox user extension after greeting)

2. Assign the FCOS containing these bits to each greeting-only mailbox that requires these passcode settings.

- Define an Administrator Mailbox
