asterisk users - Apr 2008 - CallerID in NZ

Hi There,

We have a Asterisk 1.4 box with a X100P card connected to a analog
line with Caller ID serrvices enabled on it. When an incoming call
appears we get the following in the log:

    -- Starting simple switch on 'Zap/1-1'
    -- Detecting post-CID distinctive ring
[Apr 15 10:38:07] NOTICE[7151]: chan_zap.c:6469 ss_thread: Got event
18 (Ring Begin)...
[Apr 15 10:38:07] NOTICE[7151]: chan_zap.c:6469 ss_thread: Got event 2
(Ring/Answered)...
[Apr 15 10:38:07] NOTICE[7151]: chan_zap.c:6469 ss_thread: Got event
18 (Ring Begin)...
    -- Detected ring pattern: 299,290,279
    -- Checking 0,0,0
    -- Checking 0,0,0
    -- Checking 0,0,0
    -- Executing [s at DID_trunk_1:1] ExecIf("Zap/1-1",
"0|SetCallerPres|unavailable") in new stack
    -- Executing [s at DID_trunk_1:2] ExecIf("Zap/1-1",
"0|Set|CALLERID(all)=unknown <0000000>") in new stack

So its not seeing the caller id. What might i have incorrect here?

Thanks

Simon
