Unity Voicemail Port Encryption

Answered Question
May 13th, 2009


I am trying to upload the certificate created by Unity version 4.0.5 into CM version 6.1.3 but i cannot see in any document how this is done.

In CM OS Administration under security > certificate management > upload certificate I have the option to select the certificate name and the Root Certificate but the name option seems to be a drop down list of existing certificates. The certificate generated by Unity seems to be a file with a .0 file extension.

Can anybody let me know how to do this or point me towards the document that explains the CM part of this procedure step by step?



I have this problem too.

CUCM 5.x and later requires the cert to have a different extension.

See this link, specifically Step 17 for more information on this:

Thanks very much this is exactly the information i was looking for. I have followed it and it now works perfectly. I did have to reboot Unity rather than just restart the services though as the ports would not answer even though they were registered. I can see the padlock on the phone when dialling vm now and on the gateway i can do show mgcp srtp detail and see the incoming vm calls looking like they are encrytpted as well. Thanks

again for the quick response.
