Setting the Caller ID for outgoing calls using ISDN or FoIP

Article # 3035981 - Page views: 102


It might be required to configure the outbound Caller ID when sending faxes.

More info:

Caller identification (Caller ID) is a telephone service, available in analog and digital telephone systems, including voice over IP (VoIP), that transmits a caller's telephone number to the called party's telephone equipment when the call is being set up. 

The information received from the service is displayed on a telephone display screen, on a separately attached device, or on other displays, such as fax machines.

Caller ID service is known by many similar terms, such as CID, calling line identification (CLI, CLID), calling number delivery (CND), calling number identification (CNID), calling line identification presentation (CLIP), and call display.


There are 3 possibilities to set the Caller ID for outgoing fax calls:

  • Via Cover command ++CID
    The ++CID command is part of the document sent, typically part of the template/cover. As described in the manual, the ++CID command must be the first line to appear in the document (otherwise it won't work).
    For example, if you set "++CID 1234" as the first line, the callerID will be "1234".

    This is the best method to set it on a per-user basis.
  • Using Cost center field
    When you enter a number in TCfW containing a % sign, this % sign will be converted to the configured cost center of the sender. Additionally, when you use a second % sign, anything before that percent is interpreted as Caller ID.
    In practice, you would enter the following into the Arr99, probably into the **ROUTE section:


    Using this, the fax simply gets the configured cost center as Caller ID. You can also add a prefix before the first percent sign, so that the complete Caller ID is a combination of prefix and cost center.
  • Via fax channel configuration
    In the number conversion table 254-283, you can set a general rule for outgoing calls to use a specific Caller ID. As described in the manual, you need a line starting with "8" to specify, if it is a rule for outgoing calls, then enter the Caller ID before a percent sign (%) followed by the dialed number.

    Then in this line, the match can be anything or a specific number like:

    The first example matches any outgoing call and sets the caller ID to "1234", the second one only matches outgoing calls starting with number "0800111" and sets the caller ID to "5678".
