name="intro">Introduction</a> </h2> <p> Caller ID is an analog service by which a telephone central office (CO) switch sends digital information about the incoming call. The Caller ID name delivery feature for analog Foreign Exchange Station (FXS) ports was first introduced in Cisco IOS® Software Release 12.1(2)XH and is available on all later Cisco IOS software releases. This feature is available and configurable on a per-port basis to phones connected to analog FXS voice ports. This feature is also available on analog Foreign Exchange Office (FXO).</p> <p> <b>Note: </b>FXS ports transmit Caller ID, while FXO ports receive Caller ID. The Caller ID interoperates with analog phones, public switched telephone networks (PSTNs), private branch exchanges (PBXs), H.323 terminals (such as Microsoft NetMeeting), Cisco CallManager, and IP phones. Therefore, Caller ID can be delivered across a telephony network that consists of all or some of these devices, with some exceptions.</p> <p>Furthermore, there is a Cisco IOS feature that allows a network designer to block Caller ID from being transmitted from the FXS port, if necessary. The Caller ID is unblocked, by default, for all calls; but, Caller ID can be blocked on a per-port basis. When you turn on this feature on any given port, it blocks the Caller ID of all calls that originate from that port. </p> <h2> <a name="prereq">Prerequisites</a> </h2> <h3> <a name="req">Requirements</a> </h3> <p>Before you attempt this configuration, make sure that you understand the command references for this feature, which are described here:</p> <ul> <li> <p> <b>[no] caller-id enable</b>鈥擡nables and disables Caller ID. Default is Caller ID disabled. This enables or disables the transmission of Caller ID on an FXS port and enables or disables reception of Caller ID on an FXO port.</p> </li> <li> <p> <b>[no] station-id number<span style="font-weight:normal; font-style:italic">string</span> </b>鈥擯rovides a station number to use as the calling number associated with the voice port. The <i>string</i> parameter is optional and, if provided, is passed as the calling number when a call originates from this voice port. If this parameter is not specified, the calling number attained from a reverse-dial-peer search is used. If no Caller ID is received on an FXO voice port, this parameter is used as the calling number. The maximum number of characters that can be used for the <i>string</i> parameter is 15 characters.</p> </li> <li> <p> <b>[no] station-id name<span style="font-weight:normal; font-style:italic">string</span> </b>鈥擯rovides a station name associated with the voice port. The <i>string</i> parameter is passed as the calling name to the remote end when a call originates from this voice port. If no Caller ID is received on an FXO voice port, this parameter is used as the calling name. The maximum number of characters that can be used for the <i>string</i> parameter is 15 characters.</p> </li> <li> <p> <b>[no] caller-id block</b>鈥擝locks or unblocks Caller ID. The default is Caller ID unblocked. This command blocks or unblocks the Caller ID of all calls that originate from this port. This command is available only on FXS voice ports.</p> </li> <li> <p> <b>[no] ring number <span style="font-weight:normal; font-style:italic">string</span> </b>鈥擳his command sets the maximum number of rings to be detected before a call is answered over an FXO voice port. The ring number command is how Cisco receives the Caller ID information after two rings.

The Caller ID is <i>not</i> supported on E&M channel associated signaling (CAS) lines. In this example, Caller ID is spoofed as though it came from the CAS line, in order to send it to the FXS port. For digital lines, only ISDN lines support Caller ID delivery by default, and CAS type <b>fgd</b> is the only CAS type to support Caller ID delivery.</p> <p>On the Cisco AS5300 and AS5800 platforms, a feature of CAS signaling Feature Group B (FGB) allows Automatic Number Identification (ANI) to be received upon configuration of the T1. If this signaling is used, the Caller ID is automatically received on the Cisco 5300 or 5800. This feature is explained further in <a href="//www.cisco.com/en/US/docs/ios/12_2/dial/configuration/guide/dafchant_support_TSD_Island_of_Content_Chapter.html#wp1038218">CAS on T1 Voice Channels</a>.</p> <p>This configuration shows only the elements that pertain to Voice over IP (VoIP) and Caller ID commands:</p> <p> <img alt="callerid_name_del_1.gif" border="0" src="//www.cisco.com/c/dam/en/us/support/docs/voice/analog-signaling-e-m-did-fxs-fxo/23444-callerid-name-del-1.gif" usemap=""/> </p> <p>The call flow is from PBX to Phone B.
