What’s New in Release 5.1.1 Revision B?


  • Polycom® Unified Communications (UC) Software 5.1.1 Revision B is a general release for all open SIP platforms, Microsoft® Lync™ 2010 and Microsoft® Lync™ 2013.

Note If you are using Polycom UC Software 5.1.1 Revision B with Microsoft Lync Server, you can register only one line. You cannot register multiple lines on one phone with Lync Server !


Please be aware of the following when utilizing UCS 4.1.0 or later:

The use of Polycom UC Software versions 4.1.X (“Software”) requires the purchase of a separate Software license for every device that will use the Software in a Lync environment. You may not install, access, or use the Software in a Lync environment on more devices than are listed on your license until additional licenses have been purchased and authorized by Polycom. These licenses should be purchased from the same company from which you purchased the devices. You may operate devices against a Lync server for trial purposes for up to 30 days without purchasing a license. Use of the Software is subject to the terms and conditions of the End User License Agreement.

Polycom reserves the right to audit your deployment to verify that you have sufficient licenses to match the number of devices being used.
