I have problem with installation of new CUCM Subscriber.
I have got new MCS Server and DVD Media with 7.1(2b)(18.104.22.168000-1).
I have CUCM Cluster running with 7.1.(5b) ( 22.214.171.124000-1).
Installation of CUCM subscriber failed due to mismatch of the above Version (release).
I have downloaded tried upgrading from UCSInstall_UCOS_126.96.36.199000-1.sgn.iso . This is not working . I have realised this ISO is useful only when upgrading from Running System (Operational CUCM Subscriber not for fresh installation).
Can I get link to download “Installation Patch” from 7.1.(2b) to 7.1(5b) or 188.8.131.52000-1 Fresh Installation media?
