No Caller ID displayed in the UK

I am using Trixbox 2.2 FreePBX 2.2.1
I installed a Rhino R4FXO card with the latest drivers from the web
I'm not a Linux techie and know little of how phone systems work but with help from this site, my Cisco 7970 and Xlite softphone now make and receive calls OK
But ..
I cannot get the Caller ID of incoming calls to display. The phones just display unknown.
I know that the pstn line has caller ID enabled.
I have been trawling the web and understand that the UK callerID is non standard and causes problems but I have now tried all the suggestions on various sites and still can't get callerID to work. I need Caller ID so that Trixbox can decide where to send the incoming call.
Here is my zapata.conf - Thanks
