asterisk users - Oct 2004 - Should ZAP channels pass CNAM to SIP?

signalling=pri_cpe
callerid=asreceived

I see that I get the callerID CNAM in the cdr records, but the 
same information does not show up on the display on my Cisco 7960 
     phone only the ANI.  I do get Callerid from voip to voip calls .
Just not on the zap to voip calls.

My question is does anyone have CNAM passing through to voip?
I am trying to figure out if I have a configuration error or this 
is a system limitation.

Sure would be nice to see the name of the weirdos that call me.
