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. |

Description |
Type | Create | Specifies the type of direct inward calling that this object defines. Values:
|
Range size | Create | This field appears only if Type is set to DID Range. It specifies the number of directory numbers in the range. All codes in the range defined by First code and Range size must have the same number of digits. For example, if the first code is 900, you cannot configure a range size of more than 100 because this gives a mix of three-digit and four-digit codes. |
(First) Directory number | Create | The meaning of this field depends on the Type field:
|
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 2-9 digits (if the Call Agent signaling type of the parent PBX is Analog line / T1 CAS), or 2-25 digits (if it is ISDN PRI or SIP). This code must be the same length as the codes for any existing direct inward dial ranges already configured for this PBX. The length of this code determines the Number of pulsed digits field on the parent PBX object.
All codes in the range defined by First code and Range size must have the same number of digits. For example, if the range size is 100, you cannot configure a first code between 901 and 999 because this gives a mix of three-digit and four-digit codes.
This field will be set to 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. |
