Sangoma A200 FXS Caller ID

I have a Sangoma A200 card with an FXO and FXS module installed. I have called ID operating ok coming in from the telco on the FXO interface. However, analogue phones connected to the FXS are not receiving caller ID. Are these Sangoma FXS modules capable of delivering caller ID information?

I am in the UK and have set the correct parameters in chan_dahdi.conf. Incoming caller ID is working fine. Anything else I need to do?
