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.
