Hi All,<br><br>Possible discuss before but I have to upgrade my CUCM 6.1 to 8.0, I have basic question in order start working on it, which version of 8 is stable one right now.<br><br>1- Can upgrade be done on same BOX or we can start with new installation and import data?<br>
2- We have 7940, 7960, 7912 and some VG224/ATA 186 and some Cisco 7936 conference (polycom Phone) is also running, if firmware will upgraded for 8.0, do we loose the old model phone, or it will run with new firmware with limited option, what are the limited option available for these phones, can we still use the fast dials/speed dials, as our most of the user use this service? What about IP communicator do we need some other version of IP communicator where we are using 2.2 right now.<br>
<br>3-Do we need to upgrade our 2811 router IOS, currently we are running 12.4(24)T4,<br>4-If we loose Auto Attendant in CUCM 8 then what are other option Cisco offering?<br><br><br>If any one have any valuable Cisco upgrading link please do let me know, <br>
<br>Thanks in advance!<br><br>AbdusSaboor<br>
