First step is to make sure that the CO trunk is enabled for Caller ID. Call your phone company and ask them or simply connect a regular phone to the line (a phone with a display), call the number and check for CLID.

Done nothing change i can receive the call but no caller-id.

Ok i receive the caller-id when i delete this command all is ok now:

cptone BE

Do you know why ?

Regards,

The commands provided in your configuration, plus the call progress tone command that I recommended should be enough for localizing the FXO port for Belgium. At this point, I would advise that you contact Belgacom and ask them how exactly are they implementing caller id for your trunks. This document is very useful for understanding how caller ID is implemented in Cisco IOS devices:
