Do you any experience with meeting button in Cisco Phone 7975 TP ? I have experience that my Cisco Phone 7975 doesn't show up meeting button. I Use CUCM 7.1.5, CTSMAN 1.6, CTMS 1.6, Exchange 2007.
Please check the free memory of CTS - Manager as well. Sometimes, because of no adequate memory - OBTP doesn't shows up on the IP Phone.
Please check and revert.
Thanks,
Saurabh
