We have deployed PIN provisioning on Lync 2013 for VVX series phones running latest UCS5.2 firmware.

 

All phones authenticate and login when using Windows DHCP Server, however will not when using third party Cisco or Junpier routers as DHCP Servers. DHCP relay is not an option unfortunatley. 

 

We have also downgraded to 5.1.3 with same results and note Polycom releases UC software 5.1.2 for VVX and SoundStructure release notes state "The phone now accepts the "Non Microsoft DHCP server provisioned Option 43".

 

PIN authentication using HP 4120 works perfectly but not for VVX.

 

Below and attached is a packet trace with the DHCP options being sent and received, a copy of the DHCP router configuration and the result of the Microsoft DHCP util that proves option 120 and 43 are correct.

 

I have hidden HEX and IP Addresses or obvious reasons.

Any ideas?

Hello murraybd,

welcome to the Polycom Community.

I am aware of a Cisco issue at present (VOIP-95799) but to verify the Juniper or Cisco issue is the same we would require you to open a support ticket via your Polycom reseller.

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

Best Regards

Steffen Baier
