Polycom 450 updating initial configuration
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.There are two types of reset procedures which accomplish different tasks in LPE.In the official Microsoft documentation these procedures are described as either a , yet these terms can be a bit misleading.Each of the two areas are completely independent and can store a full, separate firmware image.This design allows for two different firmware versions to be installed allowing the phone to switch between them when needed.
For example a brand new device might leave the manufacturing line with only the original RTM firmware release installed and the inactive partition might still be blank.
Most administrators would typically think of the ‘factory reset’ phrasing as synonymous with reverting a device back to the exact configuration it was shipped from the factory with, which might include both the parameter configuration and the version of firmware.
That type of reset is very common among networking devices for example, and is typically accomplished by the device having some read-only area of memory in which this original firmware is saved and can always be recalled. Going back to the original Tanjay device running the first release of Lync Phone Edition all LPE devices use the same design of a dual-partition design consisting of an .
These processes were originally documented in the article Externally Provisioning Lync Phone Edition.
Note that these reset processes are different between the Aries family of phones (CX500/600/3000) and the older Tanjay phone (CX700) models.
