Cisco Unity Connection (CUC) Media Master Issue

Okuma süresi: 3 dakika

Last month, I came across a problem in CUC when I tried to upload new greeting record. Firstly I thought it was probably based on wrong file format. But after I checked it, I understood the file format was not the source of my problem.


So I gave it some time to resolve it and then I saw it was originated from JAVA !!
I will write down the steps that I used to resolve my issue, respectively.

Close all of the browsers

– Verify that all processes are cleared in Task Manager [Ctrl+Shift+Escape]] or type in the search start menu “view running processes with Task Manager”; you should not see any processes like specified below.

* firefox.exe
* iexplore.exe
* chrome.exe

Remove existing Java that is installed

– uninstall Java 6,7,8
– delete all the sub-folders in “C:\Program Files\Java” or “C:\Program Files (x86)\Java”
– clear cache and browser history
– download Java from the official site – 1.7.0_71

Windows x86 Offline 28.09 MB jre-7u71-windows-i586.exe


– run install file as Administrator
– verify that Java is installed successfully

Disable Java security

– after Java installation type “Configure Java” at the Windows search start menu and you will see similar output to the below.


Clear temporary files in the Java



Set the security level and exceptions

– Security Level = Medium
– Exception site list. Add the CUC sites for PUB and SUB. Edit Site List.


Disable security verification in Java

Mixed code disabled = DISABLE VER
Perform certificate revocation checks = Do not check
Advanced security settings = ALL

Permit access for CUC nodes to local Java modules by editing java policy file

– open “C:\Program Files\Java\jre7\lib\security\java.policy” as administrator
– open “C:\Program Files (x86)\Java\jre7\lib\security\java.policy” as administrator

– after a line below
permission “localhost:0”, “listen”;

– add lines below and then save a file
permission “”, “connect,resolve”;
permission “”, “connect,resolve”;
permission “”, “connect,resolve”;
permission “”, “connect,resolve”;

Verify Java is running and enabled on Mozilla

In the example I used Java v7u67. Verify Java v7u67 is running and enabled on Mozilla. You should see “Java(TM) Platform SE 7 U65” or different version. JDK (Java Deployment Kit) is not required.


– open Mozilla as administrator
– clear cache and browser history
– verify that Java IMMApplet starts
– you will see at least Java logo below and maybe some security warnings

If instantly you will see some error message then it means that Java is not enabled for this browser. Error message next is really common one – “Init MMApplet Instance Failed To Get Instance”. Make sure that Java was installed with browser process not running in the background.
