A Lync 2013 Edge server is using external, 3rd party certificates for authentication and encryption of data for federation purposes and external clients connecting to the Lync 2013 environment. I’m using Digicert certificates for this since these work fine in almost all situations.
So I got a message from Digicert to renew my certificate, which I did. Renewed the certificate, same Common Name (CN=access.exchangelabs.nl) and the same Subject Alternative Names entries. The order of the SAN entries was different and so was the Friendly Name of the certificate but this should not cause any problem.

When using Lync Phone Edition you might want to upgrade to Lync client on these phones when they become available. The distribution method for this is via the network (of course).
The update process is as follows:
- Downloaden from Microsoft update;
- Upload the update to the Lync Server;
- Approve the update;
- Auto install of the client software on the device.
Step 1 is to download the appropriate updates when they are available. For the Microsoft Lync Phone Edition for Polycom CX500, Polycom CX600 and Polycom CX300 they can be downloaded here: http://www.microsoft.com/en-us/download/details.aspx?id=23866, but there are also updates available for Microsoft Lync Phone Edition for Polycom CX700 en LG-Nortel IP Phone 8540 or for Microsoft Lync Phone Edition for Aastra 6721ip en Aastra 6725ip.

When using a Lync server infrastructure it is possible to use Lync Phones without connecting them to a PC using the USB cable. Devices like the Polycom CX500, CX3000, Snom UC600 or Aastra 6725ip are just a few examples. Since these clients are not connected to the PC they have to get their configuration information somewhere else.
This information is retrieved by the clients using DHCP. In DHCP the following options are used:
- 001 UCIdentifier;
- 002 URLScheme;
- 003 WebServerFqdn;
- 004 WebServerPort;
- 005 CertProvRelPath;
- 120 UCSipServer;
- 042 NTP Server (Optional);
While it is possible to configure these options manually there’s a tool in Lync that will retrieve the appropriate information and configure DHCP for you!

When a Lync phone (in my scenario a Polycom CX700 and a Polycom CX3000) is connected to a Computer using a USB cable you can use the Lync client on the PC to logon to the Lync servers. An additional pop-up is shown where the credentials have to be entered:
But the Lync client will not logon and the pop-up appears all the time. At the same time you may see a message like “Cannot download certificate because domain is no accessible. If the problem persists, contact your system administrator” or something like this.
