Do we need special patch ?
We have installed latest version on Campus Manager and the IP Phones desserved by CCM 7.0.2 are not detected ?
We have 2 CCM cluster, phones in CCM 4.2 are well detected.
Yes, you will need to enable the CISCO-CCM-MIB on your Call Manager. I believe that is done under Tool > Control Center - Feature Services on the CCM.
