Updating to 10 5 6
Prerequisites: -Before beginning this guide, I would recommend that your i Drac7 be at the latest firmware.-Download the appropriate firmware update for the component we are updating.The process can be used on phones connected to Lync Server 2013, Skype for Business 2015 Server, or Skype for Business Online environments.
While each of these platforms are currently using versions in the 5.4.x branch the actual release versions may or may not have the exact same build number between the different platforms.Note that it is possible to load the wrong firmware on a device in the event that the software packages are somehow mixed up between these various products.From a software standpoint the Trio platform is based on the same (UCS) platform that the entire line of modern VVX phones use, thus the majority of upgrade options are the same.In fact this is a very similar process to what the CX5100/5500 also supports for firmware upgrading.
(Note that while the some VVX desktop phone models do include a standard USB port they do not currently support this USB upgrade method.) While most any USB flash drive should work for this process it is recommended to use a USB 2.0 drive.As stated because the Trio uses the same base UCS platform then the Trio will adhere to any existing DHCP, LLDP, or other network configuration parameters specific to the IP phones. The Microsoft native firmware update process that was added to Lync Server 2010 to support Lync Phone Edition devices has been supported by Polycom VVX phones for over two years now, as of the initial 5.0 firmware release.
