Yes, I have had CLI working with a TDM400P. It took some fiddling with
various flags to hit the right combination. You must use a UK ring
cadence on the extensions phones for it to work.

If you add the following to zapata.conf, it should work - although I
have not tested it with the latest head release:

usecallerid=yes
cidsignalling=v23
cidstart=polarity
ukcallerid=yes

Unfortunately I couldn't get the TDM400 to do hangup detection
properly on a BT line, which meant the line was permanently engaged
after people attempted to leave voicemail or use an autoattendant -
this is a defect that is acknowledged by Digium, but they seemed
unwilling to fix it - so I had to ditch it in favour of the SPA3000.

The advantage of the SPA3000 is that in the case of PBX failure, the
exchange line is automatically patched through to the SPA3000's FXS
analogue port, so you have at least one phone which will always work
properly, even if your asterisk server has fallen over.
