Polycom phone stuck at updating initial configuration
The phones covered in this article fall into two separate categories: Lync Phone Edition (LPE) devices.These categories are quite different in their design.The phones will look for specific firmware files to perform an upgrade/downgrade and will download and upload configuration data in XML files.Polycom UCS devices can utilize a variety of different file server platforms to store and manage both firmware packages and configuration files, no additional third-party software is required.And test we did – running several conferences internally, with remote participants, audio-only, video-only and audio/video. “Phenomenal.” Careful not to tap on the table; the hub picks it up! Video Quality: In JB’s comment last week, he mentioned that he’d occasionally see remote meeting participants’ video freeze up.But only on the Trio – when viewing on a laptop, no freezes occurred.
Also note that some of this guidance differs from instructions found in the official Polycom provisioning guides, most importantly the guidance to use a large number of parameters which no longer need to be defined for Lync interoperability as of the introduction of the Lync Base Profile. CX600) receive all of their provisioning information and software update packages directly from a Lync server. VVX400) do also receive a lot of information in-band from the Lync Server, UCS devices contain a variety of configurable parameters available outside of what the Lync Server can provide itself.
Resetting configuration data or rolling back the firmware on Lync IP phones is one of the most basic troubleshooting procedures, but at the core is also often misunderstood.
This article will cover the reset procedures as well as explain what is actually happening on the devices.
When looking to provision any of these out-of-band features, like Paging, or when dealing with device firmware updates then it is required to deploy a centralized server to provide this today.
The provisioning server is not a specific product or solution, it is basically just a centrally-accessible file store which contains certain files that the devices are programmed to look for.
