Multiple Appearance Directory Number

The Multiple Appearance Directory Number (MADN) object defines an external number that can be used to access multiple lines within a Business Group, so that all free lines associated with the MADN ring when the number is dialed. It is a child of the Multiple Appearance Directory Numbers object.

A MADN has up to 32 MADN Member child objects, each corresponding to a Business Group Line that rings when the number is dialed.

To configure and enable a MADN, you need to do the following:

When you first enable the MADN, most of the subscriber services are disabled by default, except for a small number that can be enabled by default in the global Call Services configuration. You can then activate individual services for the MADN as required.


Parameter

Access

Description
Pilot directory number Create The directory number (full national telephone number including the leading zero) that an external caller dials to access the MADN. Either type in the number (noting that the directory number must be within the parent Business Group Number Block if you set the Number status to Normal, Ported from, or Non-geographic), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use. If you click on the ellipsis symbol, the dialog box that appears presents sub-ranges from the parent Business Group Number Block. Select the sub-range from which the number should be taken and click on Next. In the next dialog box, select a number and click on OK to accept this number. (If no number is shown, this indicates that there are no free numbers in the range; click on Back and select a different number range.)
Persistent Profile Change The Persistent Profile that is used as a basis for the configuration of this MADN and its call services. The default values for many other fields in the MADN's configuration are taken from the selected profile. Select from the list of Persistent Profiles that are configured for use by MADNs, or select Persistent Profile "None" to use the system defaults instead of using a profile.
Call limit algorithm Change Specifies how the NE should limit the total number of concurrent incoming calls to the MADN. When this limit is reached, any further incoming call attempts will receive a busy indication. Note that an incoming call to the MADN counts against this limit only if it is connected to a Business Group Line that is a direct child object of the MADN; calls connected to another MADN or MLHG that is a child of the called MADN are not counted. Choose Use default or specify a value:
  • Total calls cannot exceed number of members
    The total number of concurrent incoming calls to the MADN, including both calls connected to Business Group Line MADN members and queued calls, cannot exceed the number of lines configured as MADN Members. Note that some calls may be queued if one or more lines are busy with outgoing calls or direct-dialed incoming calls to a MADN Member.
  • Total calls cannot exceed specified value
    The total number of concurrent incoming calls to the MADN, including both calls connected to Business Group Line MADN members and queued calls, cannot exceed the number specified in the Call limit value field.
  • Queued calls cannot exceed specified value
    The total number of queued incoming calls to the MADN cannot exceed the number specified in the Call limit value field.
Call limit value Change This field appears only if Call limit algorithm is set to Total calls cannot exceed specified value or Queued calls cannot exceed specified value. Choose Use default or specify the maximum total number of incoming calls (minimum 1) or the maximum number of queued calls (zero indicates that calls will never be queued).
Intercom dialing code Read only If the MADN's directory number is included within an Intercom Code Range defined for this Business Group, this field shows the intercom code that subscribers within the group can use to call the MADN.
Number status Change Inactive Specifies the status of this number. Values:
  • Normal (default)
    Normal number on this exchange.
  • Ported to
    Number from a different exchange that has been ported to this exchange (for use by a subscriber connected to this exchange).
  • Ported from (UK only)
    Number ported from this exchange to a different exchange (for use by a subscriber connected to that exchange).
  • Ported out (North America only)
    Number ported from this exchange to a different exchange (for use by a subscriber connected to that exchange).
  • Reserved - ported in (North America only)
    Number from a different exchange that has been ported to this exchange, but is not yet in use by a subscriber connected to this exchange.
  • Recently moved
    Number that a subscriber has recently stopped using, to change to another exchange or to another number on this exchange. When someone calls this number, the NE plays an announcement about the change.
  • Reserved - old number
    Number that has previously been used and is being kept for a period of time before re-use.
  • Reserved for future use
    Number that has been reserved for future use.
  • Non-geographic
    Non-geographic number owned by the local exchange. This number status is used when there is a requirement to define a subscriber with a non-geographic Directory Number. Calls to this subscriber will only succeed if this switch and adjacent switches are configured to route calls directly to this number without performing AIN non-geographic number lookups.
Recently moved from old number Change Inactive Specifies whether this subscriber has recently moved to this directory number from a different number. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Values:
  • True
  • False (default)
Moved from directory number Change The old directory number from which this subscriber has moved. This field appears only if Recently moved from old number is set to True. Specify the number as a full national telephone number including the leading zero.
Connect call after announcement Change Inactive This field appears only if Number status is set to Recently moved. Specifies whether a caller who calls the old number should be connected to the new number after an announcement. Values:
  • True
    The caller hears an announcement about the number change, and is then connected to the new number. The field Moved to directory number must specify a local number on this MetaSwitch NE.
  • False (default)
    The caller hears an announcement that the number has changed, but is not automatically connected.
Moved to directory number Change Inactive The new directory number to which this subscriber has now moved. This field appears only if Number status is set to Recently moved, and is required if Connect call after announcement is set to True. Specify the number as a full national telephone number including the leading zero.
Ported exchange ID Change Inactive The ID of the exchange to which calls for this subscriber should be redirected. This is a 5-digit number, allocated by the OFTEL Numbering Unit. When redirecting the call, the local exchange identifies the target exchange by adding a 6-digit prefix to the called number; the prefix consists of the digit 5 followed by this exchange ID. This field appears, and must be supplied, only if the Number status field is set to Ported from.
PIN Change The personal identification number (PIN) that this subscriber should use to access services related to their phone line. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. You must specify a valid PIN before the subscriber can access any services that require a PIN. Specify a 4-digit number.
