A Wi-Fi Polycom VVX

Whilst browsing the UCS 5.8 release notes I couldn’t help but notice the addition of support for Wi-Fi connectivity, added to all phones in the range that possess a USB port (except the VVX1500 apparently). This is delivered via an Obihai USB dongle, the “OBiWiFi5G” – which I was able to pick up for $AUD45 at the Bays Du e. So now we have the makings of a wireless VVX…

VVX500 dongle

Well, it’s only kinda wireless – it’s still tethered to power, and that hardly makes it wireless. I wondered what we could do about that… but I’ll address that in my next post.

Lync 2013 / SfB 2015 Client Update – September 2018

It’s been a month since our last update to the client and our fresh Spring update [here in the southern hemisphere] brings one fix. Kb4092457 takes the Office 2013-based client from 15.0.5059.1000 to “15.0.5067.1000” (according to the KB).

Optimising Polycom VVX background images

If you go looking for the details of the wallpaper or background image sizes for the VVX family of phones you might fall into the same trap I did.

You might have seen this table in the documentation:

Phone model Optimal background image size (in pixels)
VVX 300 and 310 208 x 104 pixels
VVX 400 and 410 320 x 240 pixels
VVX 500 320 x 240 pixels
VVX 600 480 x 272 pixels
VVX 1500 800 x 480 pixels

What isn’t immediately apparent is that this is the FULL screen size, not the USEABLE size. Place a logo too close to the top or bottom and it will be cut off by the “title bar” with the time display and line details at the top, or the softkeys at the bottom.

It also became clear in the process of testing this that despite the 400- and 500-series having the same absolute size, their useable size differ slightly, potentially requiring a different background image for each.

If you click the Sonus category here you’ll quickly notice that I’ve written about the Sonus/Ribbon REST interface on and off for years now, as it’s such a handy way of peeking and poking into the SBC without interacting with the browser.

And so it came to pass last week that when presented with a challenge, I’ve again resorted to REST and PowerShell to deliver the fix.

The challenge – refresh the AD Cache

My customer is planning on migrating a couple of thousand users to Skype for Business quite gradually, and for that we’ve proposed the fairly standard upstream model, with the SBC doing AD lookups to determine if a user is enabled for SfB and thus decide where to send the call. If you’re not familiar with it I drew a picture and added an explanation at the top of this post back in 2014.

The catch is that the SBC’s minimum refresh period is an hour, and the customer doesn’t want to be potentially waiting that long for it to kick in after a user’s been migrated. They’re also big users of automation, and so logging into the SBC to clear the cache by hand isn’t really an option.

The fix

Thankfully Sonus added the option to clear the cache to their REST interface, and it didn’t take me a lot of effort to “save-as” a script I’m working on (more on that soon) to come up with “Update-RibbonADCache.ps1”.

Recover Ribbon SBC AD Password

The Sonus/Ribbon Enterprise family of SBCs has a great feature where it can use your Active Directory as both a means to authenticate logins, and also to dynamically make changes to your call routing.

It does this by using a service account to authenticate to AD and query the relevant attributes or group membership, depending on which of the above features is involved.

Whilst the password to this account is saved in the backup files and encrypted, I recently found that if you possess a REST login for the SBC you can use that to recover the password.
