The Polycom CX600 is a Lync Phone Edition (LPE) device that is optimzed for Lync2010 and Lync2013 environments. As briefly mentioned in the KB Article for the January2013 CU for LPE devices, this new firmware update actually allows the phones to support Lync Online and Office365. This article descibes how to configure the CX600 for use in Office365 Plan E4 in a lab environment. For Lync On-Premise scenarios, fellow MVP Jeff Schertz has written excellent blogs on how to configure these phones for Lync available here.
Since the phones require users to be enabled for Enterprise Voice, only Office365 Plan E4 or Lync Online Plan 3 can be used with the Lync Phones as only these plans include the Enterprise Voice" feature equivalent in Lync On-Premise, which is refered to as "Lync-to-Phone" in Lync Online. In US and Canada, the "Lync-to-Phone" PSTN connectivity is provided by service provider JahJah and this service is not currently available anywhere else in the world. For Office365 users outside US and Canada, PSTN connectivity can still be achieved by deploying an On-Premise Lync environment with PSTN connection via a qualified gateway while still using Lync and Exchange Online in the cloud. These are refered to as Hybrid Lync Server deployments. Details on how to configure phones for these hybrid scenarios will be covered in a future article. In this article we will not configure any PSTN connectivity.

| For UM to work on the phone, Exchange Online Plan 2 is also required as that includes the UM features that allows the phone to gather call logs and retrieve/playback voice mails. Since Office365 Plan E3 includes Exchange Online Plan 2 but only Lync Online Plan 2, the CX600 phones cannot be used for E3 and attempting to login on the phone using a E3 account results in the error as shown on the right: |  |
Getting Started: Configuring Exchange Online for UM
To allow the CX600 phones to retrieve VoiceMail and Call Logs, the Exchange Online service must be configured for Unified Messaging UM). To get started, navigate to the Exchange Admin Center and select Unified Messaging on the left tab. Then Click on the "+" button to add a new UM Dial Plan as shown below:
On the new UM Dial Plan window, we enter a desriptive name for the dial plan followed by the Extension length which would be the number of digits in the full E.164 number excluding the "+". For eg if the country code is 65 followed by another 8 digits, then extension length would be 10 digits. Next select the "SIP URI" Dial plan type and select the desired audio language.
