| Title |
How to enable the Caller ID (CLID) name delivery feature on Cisco IP phones for inbound PSTN calls on the FXO port |
| Core Issue |
Caller ID is an analog service by which a telephone central office (CO) switch sends digital information about incoming calls. 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. It is available on all subsequent 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). |
| Resolution |
The [no] caller-id enable command enables or disables the transmission of Caller ID on an FXS port, and enables or disables reception of Caller ID on an FXO port.
Issue the [no] caller-id enable command to enable the Caller ID name for inbound PSTN calls on the FXO port.
You must configure the alerting method when the Caller ID standard, specified by locale through the cptone command, is not Bellcore/Telcordia. If you do not configure the alerting method, the default caller-id alerting ring 1 command is applied. The command that you enter is determined by the Bellcore/Telcordia or ETSI standard that your service provider uses for Caller ID.
Refer to the Configuring Voice Ports to Support Caller ID section of Caller ID on Cisco 2600 and 3600 Series Routers and Cisco MC3810 Series Concentrators for more information on using commands and issues related to Caller ID on analog ports.
Note: This command works only if the gateway is configured as H.323 with the Cisco CallManager. If a Media Gateway Control Protocol (MGCP) configuration is used, Caller ID is not supported on the FXO port. Refer to TAC CC case K20807102 for more information.
Note: Caller ID is disabled by default. |
