Calling-Name H323 - Not Showing on Phones

Hello All,

I'am having an issue where when using H323 on a 2851 gateway with CUCM 7.1.2, the calling name does not show up on the phones. Now I have done some research on this and I have configured the following. I read that the h225 command "h225 display-ie ccm-compatible "is now integrated into the IOS". Do I need to switch to a code that has the command as a configurable option? I have checked with telco and they are sending us the calling name in the setup messages, I do not see it in the H225 q931 debugs. Any help would be much appreciated thanks!!

Everyone, I rolled back to IOS 124-11.XW10.bin and inputed the following commands and now calling-name works.

voice service voip

h225 timeout ntf 300

h225 display-ie ccm-compatible

Has anyone gotten H323 calling-name to work with a new IOS where these commands are apparently integrated into the IOS?
