I'm new to the Polycom family of products, so I'm hoping someone can help me out. We purchased two new CX700 and they came with Firmware v1.0.522.34. We're currently running Lync Enterprise Server 2013, and I've read online about how you can't jump right to the latest firmware; you have to go to CU June 2012 (CU5) first (http://blog.schertz.name/2012/08/lync-phone-edition-cu6-upgrade-issues/).
So I did that and Lync Control Panel has version 4.0.7577.4066 as the approved version for the CX700. However, the handset still doesn't seem able to update properly. It still continues to show a "Last Update Status" of "(0x2ee7/0)."
I've verified that our DHCP settings are correct by using Microsofts included "DHCPUtil.exe -EmulateClient" (http://blog.schertz.name/2010/12/configuring-lync-server-for-phone-edition-devices/). Here's the final output with the full server name redacted:
Result: Success DHCP Server : 10.1.3.1 SIP Server FQDN : <FQDN> Certificate Provisioning Service URL : https://<FQDN>:443/CertProv/CertProvisioningService.svc
I know it's looking for updates because the "Last Update Request" continues to update.
Whenever you attempt to login to the phone, it finds the time server and then gives the message "Cannot sign in to Communications Service. You must update your version of the software. Contact your system administrator."
If I go on my Lync FE Server and look at the IIS logs, I can't seem to find anything relevant (maybe I'm not looking properly).
I'm really hoping that someone can help me figure out what to test next and get this figured out. I need to get this handset rolled out soon. Thanks!
