Unable to register a VVX500 to LYNC 2013

I set up a Lync 2013 enterprise, everything is fine. I can create user, sign in by Lync 2013 client, chatting, share desktop normally, and call by this software to software with the extension number as well.

However I cannot register VVX500 phone to Lync 2013, I run UC 4.1.2B but it is not successfull. What did I miss?

Thanks for your help

Hello tombeck,

welcome to the Polycom Community.

I have moved your post from your originally replied post as they are not related.


Since you started this post the latest UCS 4.1.5 Software has been released but I doubt this would change anything on your original problem.


You should provide some kind of information what you have done to setup the phone.


Our Polycom colleague Jeff Schertz describes in great detail => here <= how to utilize the Polycom phones with LYNC.


The latest Software releases also support PIN authentication.


The most common issue is the network environment is not prepared to provision the certificate via DHCP Option 43 and also option 120. Missing DNS entries also add to provide a negative experience.


If the network is correctly configured so CX Phones are working out of the box simply pressing the multiple key combination (mkc) via 1,4 and 9 on the VVX500 will reboot the phone in LYNC mode and you then simply use PIN Authentication to sign into LYNC.


If above fails it is an issue within your LYNC infrastructure and you will need to contact your Polycom reseller and/or Polycom support. You may get requested to work with Microsoft directly.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
