Outlines FXS and FXO caller ID configuration and management, including per-port settings, CLI add-on template usage, signaling type changes, and guidance to prevent configuration mismatches between device and network setups.
Caller ID is an analog service that
-
enables a telephone central office switch to send digital information about an incoming call,
-
is configurable on a per-port basis for analog FXS ports and is also available on analog FXO ports, and
-
relies on the identity of the calling party for its features and requires proper configuration management to prevent mismatches between device and network configurations.
You can configure FXS and FXO caller ID features in Cisco IOS XE Catalyst SD-WAN device by using CLI add-on feature templates. For detailed information about CLI add-on feature templates, see CLI Add-On-Feature Templates.
If an FXS voice port has caller ID commands configured, remove all the caller-id configurations before changing the signaling type from loop-start or ground-start to Direct Inward Dialing (DID).
If you remove a voice port from a device after a caller ID command is configured, remove the caller ID configuration from the device. Otherwise, a voice port configuration mismatch occurs between the Cisco IOS configuration and the Cisco Catalyst SD-WAN configuration.
