No caller ID on UC540 SPA phones with Comcast voice trunks.

I have spent 2 hours on the phone with a cisco engineer and 2 hours with Comcast.  Neither will accept responsibility for the issue.  I can confirm that a test phone hooked up straight to comcast trunk shows proper caller ID.  Anyone have this issue before?

 

Customer has a UC540.

Can you please provide more information regarding the architecture and configuration?

 

Thanks,
