Last Updated : Feb 10, 2021 |

The system displays some features only if the associated feature is set to y on the Feature-Related System Parameters screen.

  • Automatic Callback

    A user can request Automatic Callback. For more information, see the Automatic Callback feature.

  • Automatic Exclusion

    A user can automatically activate Privacy Exclusion when the user goes off hook at a telephone that has an assigned Exclusion button.

    If you set this field to n, the user can use manual exclusion when the user presses the Exclusion button, either before the user dials a call or during a call.

    The system displays this field when the Automatic Exclusion by COS field on the Feature-Related System Parameters screen is set to y.

  • Call Forwarding All Calls

    A user can forward all calls to any extension. For more information, see the Call Forwarding feature.

  • Call Forwarding Busy/DA

    The system can forward calls when the user is active on a call, or does not answer a call. For more information, see the Call Forwarding feature.

  • Client Room

    Users can access the Check-In, Check-Out, Room Change/Swap, and Maid status functions. In addition, Client Room is required at consoles or telephones that are to receive message-waiting notification.

    You can administer a COS for Client Room only when you have Hospitality Services and a Property Management System (PMS) interface. See the GuestWorks® and DEFINITY® Systems Technician Handbook for Hospitality Installations for more information.

  • Console Permissions

    A user having a multiappearance telephone can use Console Permissions, to control the same features that the attendant controls. You might assign this permission to front-desk personnel in a hotel or a motel, or to a call center supervisor. With console permission, a user can:

    • Activate Automatic Wakeup for another extension

    • Activate and deactivate controlled restrictions for another extension, or group of extensions

    • Activate and deactivate Do Not Disturb for another extension, or group of extensions

    • Activate Call Forwarding for another extension

    • Add and remove agent skills

    • Record integrated announcements

  • Data Privacy

    A user can enter a Feature Access Code (FAC) to protect a data call from interruption by any of the system override or ringing features. For more information, see the Privacy feature.

  • Extended Forwarding All

    A user can use Call Forwarding All Calls from an off-site telephone.

    You can change a COS to y, only if the Extended Cvg/Fwd Admin field on the System Parameters Customer-Options screen is set to y. For more information, see the Extended User Administration of Redirected Calls feature.

  • Extended Forwarding B/DA

    A user can activate Call Forwarding from an off-site telephone.

    You can change a COS to y only if the Extended Cvg/Fwd Admin field on the System Parameters Customer-Options screen is set to y. For more information, see the Extended User Administration of Redirected Calls feature.

  • Off-Hook Alert

    You can change a COS to y, only if either the Hospitality (Basic) field or the Emergency Access to Attendant field on the System Parameters Customer-Options screen is set to y. For more information, see the Emergency Access to Attendant feature.

  • Personal Station Access (PSA)

    A user can use a FAC to associate a telephone to the extension that is assigned to the user.

    You must set this field to n for virtual telephones.

    You can change this field to y, only if the Personal Station Access (PSA) field on the Optional Features screen is set to y. For more information, see the Personal Station Access feature.

  • Restrict Call Fwd-Off Net

    If you set this field to y, a user cannot forward calls to the public network.

    For security reasons, type y in the Restrict Call Fwd-Off Net field for all COS, except those that you use for special circumstances. For more information, see the Call Forwarding feature.

  • Trk-to-Trk Restriction Override

    Security alert:

    You increase the risk of toll fraud if you allow users to perform trunk-to-trunk transfers.

    A user can override any system COR-to-COR calling party restrictions that would otherwise prohibit the trunk-to-trunk transfer operation for a user with this COS. For more information, see the Transfer feature.

From Communication Manager, Release 3.0, the Class of Service screen has a new field VIP Caller. The VIP Caller field enables automatic priority calling to extensions when it is marked y on the Class of Service screen. The default for this field is n.
