The Direct Inward Calling Number object is a child of the Direct Inward Calling object. It defines how external callers can dial directly into individual terminals on the PBX, either by specifying a range of external directory numbers that map to these PBX terminals (Direct Inward Dialing, DID) or by specifying an external directory number that connects directly to the PBX so that the caller can specify an internal extension number (Direct Inward System Access, DISA).
![]() |
The object's name is displayed in the EMS Tree View as either DID Range or DISA Number, depending on the value you specify for the Type field. |
You can limit the calls coming to a particular DID Range or DISA Number as follows.
When these limits are reached, any further calls will be treated as though the PBX is busy. These limits do not affect outgoing calls, so it is still possible for all lines to be busy even when the limits are in place, because the remaining lines are taken up with outgoing calls.

Last Directory number | Read only | This field appears only if the Type field is set to DID Range; it specifies the last directory number in the range. |
First code | Change | This field appears only if the Type field is set to DID Range; it specifies the code that will be pulsed to the PBX to identify the terminal corresponding to the first directory number in the range.
Specify a numeric code of 2-10 digits (if the Call Agent signaling type of the parent PBX is Analog line / T1 CAS), or 2-25 digits (if it is SIP).
If you do not specify a value, the EMS supplies a default value if the following criteria are met.
|
Last code | Read only | This field appears only if the Type field is set to DID Range; it specifies the code that will be pulsed to the PBX to identify the terminal corresponding to the last directory number in the range. |
Limit incoming calls | Change | Specifies whether to limit the number of simultaneous incoming calls to this number or range of numbers. Values:
|
Maximum incoming calls | Change | This field appears only if Limit incoming calls is True. The maximum number of simultaneous incoming calls to this number or range of numbers. When the limit is reached, any further calls will be treated as though the PBX is busy. |
Number status | Change Inactive | Specifies the status of this number, or each number in this
range. Choose Use default to inherit the value from the parent PBX,
or specify a value. Values:
|
Connect call after announcement | Read Only / Change | This field appears only if Number status is set to Recently moved. This field is read only, and takes its value from the parent PBX, if Number status is set to use default.
Specifies whether a caller who calls the old number should be connected to the new number after an announcement. Values:
|
Moved to directory number | Read Only / Change | This field appears only if Number status is set to Recently moved, and is required if Connect call after announcement is set to True. This field is read only, and takes its value from the parent PBX, if Number status is set to use default. The new directory number to which this subscriber has now moved. Specify the number as a full national telephone number including the leading zero. |
Ported exchange ID | Read Only / Change | The ID of the exchange to which calls for this nnumber should be redirected. This is a 5-digit number, allocated by the OFTEL Numbering Unit. When redirecting the call, the MetaSwitch NE 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. |
