Polycom VVX 310 upgrade

We have Lync server 2013 in our envirenment and approx. 700 Polycom VVX 310 IP Phones. As of now firmware version is

We are planning to upgrade it to 5.4.2 Rev D. Can we directly upgrade to 5.4.2 Rev D ? Also i see the noted in download link "The use of Polycom UC Software versions 5.4.2 Rev D requires an individual license per device which can be used with Microsoft Skype for Business and Microsoft Lync environments"

Do we need to purchase new licence to use 5.4.2 Rev D?

Please suggest

Hello PACT,

welcome back to the Polycom Community.

The usage of Polycom phones in a LYNC environment with LYNC / Skype always either requires to purchase the phones in LYNC base profile or purchase the relevant License pool.


You can only "test" the Phones with LYNC for 30 days.
