Updating site certificates
This applies only if you are enrolled in courses through more than one organization, and you are using the same sign-in credentials for both.This only applies to devices which are already running at least version 4.0.0 of the UCS firmware.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).The Polycom SIP phones support a few different methods for software updates, most commonly utilizing a central FTP provisioning server so that all devices will check a single distribution point for configuration changes and new firmware images.Either way once the directory is setup then any device can be manually pointed to the directory and the phone will utilize HTTP to download and apply the firmware.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.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.For engineers looking to carry phones around to different sites for demonstration purposes then selecting a web server on the Internet makes it very easy to update the phones over the Internet, while for supporting updates for a handful of devices on an internal network then utilizing an existing web server is ideal.
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.
For this reason it may be necessary to download the available software package for the 4.1 release and then create a custom distribution server to point the devices to.
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.
The previous article mentioned above contains links with more details on enterprise deployment and management practices.
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.
