Hi all,
I had a qurie on "Phones registration." Recently We upgraded CUCM from Version 6.0 to 8.5 but for some sites devices (Phones) are partially registed (Half of the phones got registed wit the CMGserver). Could any one tell me what would be the main reason to this kind of problems.
What would be the precautions we need to take on Firmware and TFTP server side.
Thank you,
