Caller ID Configuration Task List

To configure the alerting method, use the following commands beginning in global configuration mode. Configuration of the alerting method is required when the caller ID standard, specified by locale through the cptone command, is other than 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. For more information about standards, see the Caller ID Prerequisites Tasks, page 814 section.
