Can you manually install Bulk administrator tool version 6* on call manager version 4.2*?
would it be compatable?
actually BAT in CUCM 6 is no longer a plugin you can install, it's installed along with the CUCM so there is really no way to install it on any other system
it's important for you to know that ALL of the plugins are version specific, you cannot mix plugins between CUCM versions. that's the reason they're not available in the web but in the CUCM admin page. whenever you upgrade or patch your system you need to reinstall all the plugins you use
