With Andrew Beezley

Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to ask Cisco subject matter expert Andrew Beezley troubleshooting questions regarding the Cisco TelePresence System, from the CTS 500 to the CTS 3210.  Andrew has offered global support for the Cisco TelePresence System for nearly two years at the Cisco Technical Assistance Center and for more than three years before that with the Cisco Remote Management Service (RMS) team. He has been with Cisco for over 11 years, and his experience includes working with foundation WAN technology with major telephone companies to identify and repair systemic problems as quickly as possible.

Hi Ben,

Thanks for you interesting questions. Let me try answering them below.

• The files you are referring to are not suitable for upgrading CUCM. Upgrade files can be found at CCO under:
  

Support -> Download Software -> Products -> Voice and Unified Communications -> IP Telephony -> Call Control Cisco Unified Communications Manager (CallManager) -> Cisco Unified Communications Manager Version 8.6 -> Unified Communications Manager / Cisco Unity Connection Updates

As you can see in there, upgrade file would be UCSInstall_UCOS_8.6.2.10000-30.sgn.iso or UCSInstall_UCOS_UNRST_8.6.2.10000-30.sgn.iso depending on wether you are currently running a restricted or unrestricted version of CUCM respectively.

In the download page you will also find the CUCM release notes (in this case http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/8_6_2/cucm-rel_notes-862.html ) where you have detailed steps for the upgrade process and where you can find information to confirm if you can do a direct upgrade from your current CUCM release to 8.6 and if your hardware will be compatible with CUCM 8.6.

• Regarding the requirement to have an independent CUCM cluster for TelePresence, it is no longer a requirement. Nowadays you can set differentiated QOS markings for TelePresence and for legacy video telephony within the same cluster so there is no problem on that side. On the other hand, it is not unusual that new TelePresence SW releases require CUCM upgrades, so if you wish to avoid upgrading the CUCM cluster where your IP telephony resides it might be a good idea to keep them separate.
  

Kind regards,

Antonio.
