In an effort to troubleshoot a caller ID delivery problem, a customer emailed you the voice
port configuration on a Cisco IOS router. Which type of voice port is it?
|
| Option A | FXS
|
| Option B | E&M
|
| Option C | BRI
|
| Option D | FXO
|
| Option E | DID
|
| Correct Answer | D |
Explanation Explanation: ✑ Configuring FXS and FXO Voice Ports to Support Caller ID To configure caller-ID on FXS and FXO voice ports, use the following commands beginning in global configuration mode: Command Purpose Step 1 Router(config)# caller-id enable Enables caller ID. This command applies to FXS voice ports that send caller-ID information and to FXO ports that receive it. By default caller ID is disabled. Note If the station-id or a caller-id alerting command is configured on the voice port, these automatically enable caller ID, and the caller-id enable command is not necessary. Step 2 Configures the station name on FXS voice ports connected to user telephone sets. This sets the caller-ID information for on-net calls originated by the FXS port. You can also configure the station name on an FXO port of a router for which incoming Caller ID from the PSTN subscriber line is expected. In this case, if no caller-ID information is included on the incoming PSTN call, the call recipient receives the information configured on the FXO port instead. If the PSTN subscriber line does provide caller-ID information, this information is used and the configured station name is ignored. argument is a character string of 1 to 15 characters identifying the station. Note This command applies only to caller-ID calls, not Automatic Number Identification (ANI) calls. ANI supplies calling number identification only. Step 3 Configure the station number on FXS voice ports connected to user telephone sets. This sets the caller-ID information for on-net calls originated by the FXS port. You can also configure the station number on an FXO port of a router for which incoming caller ID from the PSTN subscriber line is expected. In this case, if no caller-ID information is included on the incoming PSTN call, the call recipient receives the information configured on the FXO port instead.
