[seantf]

Hi All,

Currently setup CME with FXO connected to telco, call is able in and outbound, but when calling in caller-id showing unknow number on phone.

Router version 15.4

please find attach for configuration and log when inbound call.

Based on your logs I would say that your Telco isn’t sending you any caller ID.

Oct 11 01:40:57.329: [0/0/0] get_fxo_caller_id:Caller ID receive failed.  parseCallerIDString:no data.

Hi Roger,

Telco used Analog phone then its shown the caller-ID in the analog phone.

Have a look at this post How to Solve Cisco Caller ID not working

This document is also a good source of information. Caller ID Name Delivery Issues on Cisco IOS Gateways

If neither of these resolve your issue please Google ”cisco fxo caller id not working” and you’ll find many post about this type of problem.

A telco can send the caller ID either on the first ring or on subsequent rings, such as the second or third. One way to determine which ring the ITSP sends the caller ID is by using an analog phone. You could also address the issue by using the ring command to make the call ring on the FXO port a few seconds before the router answers the call, allowing time for the router to receive the caller ID.

In my region, I use ring number 3 so that the router waits 3 seconds to answer the call, allowing time to receive the caller ID. If I set the ring number lower than that, I would never see the caller ID.

ake sure you have the CP tone set correctly.

- Ensure that your telco is configured to send caller ID. Some providers require you to enable caller ID on their end. Contact them to verify.
- Check your FXO port configuration in the Cisco CME router. You need to ensure that the caller ID feature is properly configured. Here’s a basic example of what your FXO configuration might look like:
voice-port 0/0/0
signaling sip
caller-id enable
- Ensure that you have the appropriate configuration for caller ID on the incoming calls. For example, you can use the following command: 
ephone-dn 1
number 1000
caller-id enable
Check these may help you
