Note that this article is quite lengthy as the entire process is described in detail, accompanied by various log entries and other examples.Yet in practice using the Lync Device Update service for VVX phone updates is identical to the process used by LPE devices.
But when trying to update the firmware for a few phones there is a new process which was introduced with the 4.0 release of UCS.
This process allows the device to be manually pointed to a Polycom hosted web server distribution point on the Internet to download and install new firmware packages from.
New devices like the VVX500 and Spectra Link phones have only ever shipped with 4.x UCS releases, while older devices like Sound Point IP phones may still have previous 3.x SIP releases on them.
In order to utilize Lync integration a This process can be used on any of the Polycom SIP Phones which support 4.x software today (Sound Point IP, Sound Station IP, VVX, and Spectra Link models).
To create a custom software distribution a software package must first be downloaded, the firmware files extracted, and then a configuration file created and modified.
There is still some initial setup required but this is a basic as creating a single XML file and then dropping it an the desired firmware files directly into any web server directory.
Also this process can be used to downgrade software if needed as multiple versions can be stored in the same location and a menu will be presented to allow the desired version to be installed.
All currently available versions of the Polycom UCS can be located in the official software release matrix online as well as on the product support page for any model SIP phone.
As of the writing of this article the Lync specific firmware release is not yet included on the Polycom Hosted Server, so primarily Open SIP only firmware releases will be available using this method.
