The latest release of the Polycom VVX 5.5.1 UCS firmware is now available for Lync and Skype for Business (SfB) environments. While the initial 5.5.0 release was published a number of months ago that was only intended for Open SIP applications and was not yet supported for Lync/SfB use.
With this release comes a large number of anticipated features and improvements related to Skype for Business.
Upgrading a Phone
This section will cover the basic steps to upgrade a single phone using the Polycom-hosted public server to directly download and apply the firmware to the phone. In order to perform this process, the phone’s internal web server must be enabled. Depending on the selected Base Profile the web server may need to be manually enabled.
Set Base Profile
As explained in many earlier VVX articles the phone must be set to the proper Base Profile when registering to various SIP platforms. Depending on the original purchasing SKU and/or status of the phone it will be set to one of two options by default: Generic or Lync. (Note that “Lync” base profile has been renamed to “Skype” in version 5.5.1, but they function the same.) When a VVX phone is set to Generic then the Web Configuration Utility will be enabled by default, but as this phone is or will be used with Lync/SfB environments it is best to set or confirm this parameter before doing anything else.
Enable Web Configuration Utility
Back when UCS 5.3 was released a new default behavior was defined for the Lync base profile which automatically disabled the embedded web server. This can be re-enabled on the VVX phone for testing or administration purposes if so desired. To perform many of the steps in this article it must be enabled now.
This phone must have access to the Internet in order to connect to the public hosted Polycom update server and perform the update described in this section.
The following sections covers enhancements to the phone user’s experience, like new authentication methods, call transfer workflow changes, group expansion, and device locking behavior to name a few.
Sign in Options
If the updated phone was factory-reset or did not currently have a Lync or Skype for Business user registered then the first screen that will appear after startup is complete will be the following new Sign In window providing up to four unique authentication options.
The new Web Sign-in process can only be used for Microsoft Office 365 Skype for Business Online users. Lync/SfB users accounts homed on an on-premises server, even in Hybrid models, cannot be used. Currently this new capability is only for Microsoft cloud user accounts.
Once the code is accurately entered it should immediately update to show the type of device being used, in this case a “Polycom Skype for Business Certified Phone”.
Once the process is completed the phone will prompt to create a device lock code. This must be created and cannot be skipped, although this new behavior can be disabled which is covered in more detail later on in this article.
Once registration is successful the standard home screen will display along with pinned Favorites.
