Is your GW configured as MGCP or H.323?

caller ID is not supported on FXO with MGCP.

Beside the the MGCP issue it appears that caller-in on DID lines is not supported on 4FXS/DID card.

In which country is this. ? What is the DID signaling scheme ?

I couldn't even get confirmed from discussion in another thread, that caller id on DID is supported by some telco in the US.

I recommend you to take a debug on the GW and a CCM detailed trace to see exactly what the GW is receving/sending and also what the CCM is sending/translating.
