Speaking of upgrades.. we've spent over a year getting our global CUCM boxes up to 8.6 and then we were able to convince management to purchase our first TX9000 telepresence unit. Unfortunately, the incapable VAR that our procurement folks selected in a far away region had never sold a TX9k, had no idea what version of CUCM we were running, and we're pretty sure lied to Cisco to make the sale in stating they performed a proper requirements check. So the tx9000 shows up and guess what - we can't use it because it requires CUCM 9.0 or 9.1. Well.. how about that.. so you think easy upgrade on the local CUCM? Well... now we find out.. nope that hardware isn't supported.. and there are some other caveats in going from 8.6 to 9.1 and so we're stuck. Nice 200 thousand dollar tx9000 sitting there and we can't use it because theres no other way to manage it - nada zip zilch zero. Yay Cisco - another sale! I'm forced to buy a small CUCM express to get 9.1 loaded up just so I can turn the damn camera on! Ok rant over... and now we are faced with having to perform the upgrades of our 8.6 to 9.1 on 9 other global clusters so we can complete my full any to any Video vision and get the full benefits of VCS so we can do video across any platform and include those evil Pcom video units. Ok now the rants over.. Can't wait for the show!
