For any Chrome users out there, as of 8.6.2 you can now use the menu system and adminster CUCM. 8.6.1 and earlier use UDM 4.5 with no Chrome support. 8.6.2 has updated UDM to 4.6 and added the following line to their menu system:
;um.ggc=(navigator.vendor=='Google Inc.');um.k4=(um.k&&/khtml\/[4-9]/.test(um.u));if(um.ggc||um.k4){um.s=1;um.s2=1;um.s3=1;}
I can finally stop using FF for CUCM only... once I upgrade everyone to 8.6.2
