cisco PRI no caller id name

Cisco IOS 12.4(15)T5

Just converted from channelized T1 to PRI.  I am no longer getting incoming caller id at the phone stations.

debug isdn q931 shows that I am getting name info from Telco.

There seems to be no "caller-id enable" for the controller, voice-port, serial interface, or dial-peer.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You have to make sure you enable it:

voice service voip
 supplementary-service h450.12

interface Serial0/0/0:23
 no ip address
 encapsulation hdlc
 isdn switch-type primary-ni
 isdn incoming-voice voice
 isdn supp-service name calling  <--- make sure this is there
 no cdp enable

What are you using for call control? CME? UCM? If UCM, is the gateway MGCP or H323?
