IPCM Class Restrictions

Version 1

    Details

    A class of restrictions (COR) is a set of limitations you apply to collections of extensions.
    You Could use to determines the numbers an extension can dial. For example, you can prevent extensions in a certain class from dialing external numbers, making long distance calls, etc.


    Resolution

    Class of Restrictions ( COR)
     Some Examples, 

     • Determines the numbers an extension can dial. For example, you can prevent extensions in a certain class from dialing external numbers, making long distance calls, etc.
    • Determines the numbers to which an extension can transfer or forward calls. For example, you can prevent users in a certain class from transferring calls outside the system.
    • Determines the numbers from which an extension can receive calls, including forwarded calls and transfers. For example, you can prevent extensions in a certain class from receiving external calls, calls from other internal departments, etc.

    Call Restriction Levels
    CORs let you set incoming and outgoing call restriction levels, which determine the priority IPCM grants to extensions (including phones, trunks, and gateways) when allocating system resources. Extensions with an assigned outgoing call restriction level can only call extensions with an incoming call restriction level the same or lower. This enables you to reserve expensive resources (such as highquality trunks) for certain extensions or subsets of users, such as company executives.
    If there are multiple extensions to which IPCM can route the call, and each has an incoming call restriction level lower than the outgoing call restriction level of the calling extension, IPCM routes the call to the resource with the highest incoming call restriction level.
    Refer to the online help topic "SIP Soft Switch Configuration: Class of Restrictions (COR)" for COR and call restriction level examples,
    as well as information and examples for least‐cost routing. Create and Delete a Restriction Class The Restrictions page (in the Management Portal, click System Configuration>SIP Soft Switch>Restrictions) lets you create and configure CORs to assign when configuring extensions. All
    tabs, except Levels, contain the Allow List and Deny List fields, into which numbers or an asterisk (*) can be entered (the asterisk indicates any number).

       Create and Delete a Restriction Class
    The Restrictions page (in the Management Portal, click System Configuration>SIP Soft Switch>Restrictions) lets you create and configure CORs to assign when configuring extensions. All tabs, except Levels, contain the Allow List and Deny List fields, into which numbers or an asterisk (*)
    can be entered (the asterisk indicates any number).
    ►To Create and Configure a Restriction Class:
    1 In the Management Portal, click System Configuration>SIP Soft Switch>Restrictions. The Restrictions page opens.
    2 In the empty field, type a name for the restriction.
    3 Click Add. The properties page opens, displaying five tabs: Calling Device, Called Device,
    Transfer, Forward, and Levels.
    4 On the Calling Device tab:
    • In the Allow List fields, type the numbers you want to allow extensions in this restriction class to call, then click the Add button.
    • In the Deny List fields, type the numbers you want to prevent extensions in this restriction class from calling, then click the Add button.
     For both the Allow List and Deny List fields:
    • You do not need to enter a specific phone number to be allowed or denied, you can type a prefix instead. For example, to disallow all calls beginning with the digit 9, type 9 in the Deny List.
    • If a number is not in either the Allow List nor Deny List, the SIP Soft Switch allows extensions in the class to call the number.
    • The Allow List overrides the Deny List. This enables you to allow calling exceptions in denied groups. For example, if you want to prevent extensions in the COR from calling all numbers beginning with a 9 except for the number 91‐415‐555‐1212, type 9 in the Deny List and the
    specific number to be allowed (914155551212) in the Allow List.

    ** Click the red x icon to remove allowed or denied entries. **

    5 Click the Update button to apply the configuration.
    6 On the Called Device tab:
    • In the Allow List fields, type the numbers from which you want extensions in this restriction class to receive calls, then click the Add button.
    • In the Deny List fields, type the numbers from which you want extensions in this restriction class to not receive calls, then click the Add button.
    For both the Allow List and Deny List fields:
    • If a number is not in either the Allow List nor Deny List, the SIP Soft Switch allows extensions in the class to receive calls from the number.
    • The Allow List overrides the Deny List. This lets you allow exceptions for specific numbers in denied groups. For example, you can use the Deny List to prevent the extension from receiving calls from the PSTN (Public switched telephone network) unless the call originates from a number you specify in the Allow List (for example, allowing calls from the number of a remote office).

     ** Click the red x icon to remove allowed or denied entries.**

    7 Click the Update button to apply the configuration.
    8 On the Transfer tab:
    • In the Allow List fields, type the numbers to which you want to allow extensions in this restriction class to transfer calls, then click the Add button.
    • In the Deny List fields, type the numbers to which you want to prevent extensions in this restriction class from transferring calls, then click the Add button.
    For both the Allow List and Deny List fields:
    • If a number is not in either the Allow List nor Deny List, the SIP Soft Switch allows extensions in the class to transfer calls to the number.
    • The Allow List overrides the Deny List. This lets you allow extensions in this restriction class to transfer calls to specific numbers from denied groups. For example, you can use the Deny List to prevent the extension from transferring the call to any international number except the number of an overseas office you specify in the Allow List. When transfer is restricted, the extension, such as hard phone, will not be able to complete a blind or consult transfer (nothing happens when the Transfer button on the phone is pressed). The phone typically provides no indication on its LCD.

     ** Reminder - Click the red x icon to remove allowed or denied entries.**

    9  Click the Update button to apply the configuration.
    10 On the Forward tab:
    • In the Allow List fields, type the prefixes to which you want to allow extensions in this restriction class to forward calls, then click the Add button.
    • In the Deny List fields, type the prefixes to which you want to prevent extensions in this restriction class from forwarding calls, then click the Add button.
    For both the Allow List and Deny List fields:
    • If a prefix is not in either the Allow List nor Deny List, the SIP Soft Switch allows extensions in the class to forward calls to the number.
    • The Allow List overrides the Deny List. This lets you allow extensions in this restriction class to forward calls to specific numbers from denied prefix groups.

    For example, you can use the Deny List to prevent the extension from forwarding the call to any international number
    except the number of an overseas office you specify in the Allow List.

    11 Click the Update button to apply the configuration.
    12 On the Levels tab, you can configure restriction levels that control the accessibility of phones or trunks/gateways in this restriction class. Each device has two restriction levels:
    • Outgoing calls restriction level ‐ An integer that determines the resources a device in this class of restrictions can access. Devices in this restriction class can only access devices belonging to restriction classes with incoming call restriction levels equal to or lower than
    the integer you specify in this field. The default is 10.
    • Incoming calls restriction level ‐ An integer that determines which resources can access devices in this class of restrictions. To use a device in this class, the calling device must have an outgoing call restriction level greater than or equal to this integer. The default is 5.
    13 Click the Update button to apply the configuration.

     ** To Delete a Restriction Class:
    1 On the Restrictions page (in the Management Portal, click System Configuration>SIP Soft Switch>Restrictions), click the red x icon to the right of the COR.
    2 Click OK to confirm the deletion.
