I have Call Manager 7.1.2. Due to some issues Cisco TAC has suggested to upgrade the Version to 7.1.3 SU2
I have downloaded UCSInstall_UCOS_184.108.40.206900-4.sgn.iso_part1of2 & UCSInstall_UCOS_220.127.116.11900-4.sgn.iso_part2 of2 from Cisco.
After adding i got the ISO file as: UCSInstall_UCOS_18.104.22.168900-1.sgn
I have transferred the image to Call Manager Publisher through SFTP.
The Problem is: When i try to do the installation of the same it gives the error " Installation Failed: Unknown Error"...
Any help would be highly appreciated.....
