Lync Phone Edition PIN Authentication and Cisco ACE Load Balancer – It’s About the Certificate Chain Group

This is truly the article I would have LOVED to have found when we first got the DHCP settings in for our Lync Phone Edition devices and other Lync phones, and were going crazy trying to figure out why the LPE devices were fine right after being tethered to a PC, but were not if someone logged in and out of them while disconnected and after rebooting. And that I sort of promised to write when I was raving about a certain switch.

The symptoms: Test-CsPhoneBootstrap works flawlessly. Other Lync phones can log on with extension and PIN. Your Lync Phone Edition device (in our case, the Polycom CX3000) will cheerfully log on with the extension and PIN if you’ve logged it in tethered to a PC via the PC’s Lync client first, but gives you “An account matching this phone number cannot be found. Please contact your support team” after a very quick flash of another error, “Account used is not authorized, please contact your support team” for the very same extension and PIN if you’ve logged out of the device and powered it down. I did what another admin did, taking a video on my phone, then replaying it really slowly – the time from entering the PIN to getting the final failure message was less than 4 seconds, and that was necessary to see the first failure message that briefly flashed on the screen.

Comparing Lync Policies – or How to Flip Just About Any Array of Hashtables in PowerShell

If you are reading this blog and can read German, I don’t need to tell you about msxfaq.de, former Exchange and now Lync MVP Frank Carius’ online (but not very alphabetical) encyclopedia of Exchange and Lync – it probably gets more page views in a day than this blog ever has. Even if you cannot read German, you have still probably run into it when searching for Exchange or Lync topics and then seriously wished you could read German – machine translation only goes so far.

Anyhow, one of the most helpful things he’s put out there and that I use all the time is a Swap-Table script. I wasn’t able to turn it up with “flip table in PowerShell” or “pivot PowerShell table” or any of several variations, so this is a little attempt to make that wonderful file findable for the English-speaking world. Scroll to the bottom and look for the “Code” section. You can make it a function in your PowerShell profile by putting the contents of that text file inside the curly braces {} of the following (code not posted here because plagiarism is evil):

function Swap-Table {
# contents of swap-table.1.0.ps1 go here

}

It has been particularly useful for comparing ClientPolicies and ConferencingPolicies in Lync, as ClientPolicy has over 70 attributes! Once you have the function in your session and you’re connected to Lync Management Shell, it works like this:

Get-CsClientPolicy | Swap-Table | Out-GridView
