Lync Phone Edition Firmware issue


Lync Phone Edition Firmware issue

Dear Experts

We are using Lync Server 2010 with client side using Polycom CX600 Lync Phone. Everything is ok if we use Polycom CX600's Lync Phone Edition running Firmware ver. "4.0.7577.296".But after we upgarde to "4.0.7577.4487" the polycom phone cannot sign in with error message "Your account is not configured to use this service. Please contact your support team". When we downgrade to “4.0.7577.296" the user can sign in will again. Please advise the cause of this issue. Is this related to Lync Server configuration? Or Is the latest firmware is not compatible to Lync Server 2010. Thanks.

Re: Lync Phone Edition Firmware issue

Hello Andy89,

Polycom and other manufacturers produce these optimized for Microsoft® Lync® or Skype® for Business devices after a reference design and the embedded OS running on the phones is provided, supported and maintained by our partner Microsoft®.

You therefore may want to reach out to the Microsoft® community and / or Microsoft® support directly instead as this is the most direct and efficient path.

Polycom is unable to add any new features into the functionality of these CX Devices
