Hands up if you’ve tried to compare 2 objects of some type to see what – if any – differences there are between them?
I tried and gave up. PowerShell’s native “Compare-Object” isn’t very helpful. It will tell you IF there’s a difference, but it’s not particularly forthcoming.
Borne of that experience comes “Compare-Objects.ps1”. You might see some similarities here with two of my other scripts (Compare-PkiCertificates & Update-SfbCertificate.ps1) as the comparison engine is essentially the same between them.
Feed this script the “type” of the object and the names of two of them, and it will present a tabular comparison, highlighting all those attributes that differ.
All of these formats are valid input examples:
Compare-Objects.ps1 –type csuser –object1 “greig” –object2 “jessica”
Compare-Objects.ps1 –type csuser –object1 greig –object2 jessica
Compare-Objects.ps1 get-csuser greig jessica
Armed with the above input the script performs two “get-” commands to query the objects, then feeds the results into the differencing engine. The “get-” is implied in the command-line input, and the script will cope fine if you absent-mindedly include it, like in the last example above.
If you’ve already captured the objects, you can feed them to the script and it will compare them directly, skipping the “get” step:
Compare-Objects.ps1 –type $null –object1 $greig –object2 $jessica
Compare-Objects.ps1 $null $greig $jessica
For more information add the “-verbose” switch, and if you don’t want it querying my blog in search of an update, use “-SkipUpdateCheck”.

Last month’s client update took us to 15.0.5023.1000, and now Kb4018377 increments us to 15.0.5031.1000.
Just the one update this month:
- Kb4133098 Location is still displayed even if UseLocationForE911Only is set to true in Skype for Business

It’s been a long while between visits to the subject of Sonus (now Ribbon) AD-based routing in the SBC1k, 2k & SWe Lite, but my colleague Tristan recently pointed out a new feature that I wasn’t previously aware of.
In my 2012 Mk-II Safety Net I showed how you could do a second AD lookup against an incoming call so as to ensure the transformation table passed regardless of whether their LineURI contained an “ext=” suffix or not.
Now it seems that’s been superseded by the addition of wildcard handling in AD lookups! [Reference]. And so here’s the Mk-III!
The Mk-III AD Lookup
For context, here’s what the Mk-II looked like:

Protocols and standards. We live and die by them, and while we can’t live without them, sometimes they can be a royal PITA. And so it is apparently, with Polycom’s interpretation of RFC4568 Session Description Protocol (SDP), with which I became all too familiar this week.
I was called in to try and figure out why a customer’s Polycom VVX’s intermittently couldn’t call out to the PSTN. They could place the call seemingly OK, but as soon as the external party answered it dropped.
Incoming calls were fine, and none of their other clients had any outgoing problems: their Office 2013 and Office 2016 PC clients were fine, as were the fading old CX600’s. Making this scenario all the more interesting is that the PSTN Gateways are NET / Sonus “VX 1200” gateways still running flawlessly from their Lync 2010 days – and still supported by the vendor until the end of 2018 BTW!
Media Bypass is enabled in this environment, so the obvious conclusion to draw was that we were dealing some some kind of incompatibility between the new-ish phones and the (ahem) “mature” VX’s.

What’s with the monthly client update cadence at the moment? No complaints here though: I personally benefit from possibly two of these fixes! The March update took us to 15.0.5015.1000, and our early April update (Kb 4018334) adds 8 builds to hit 15.0.5023.1000.
This update fixes the following issues:
- Kb 4095404 A call to yourself is initiated when you add audio to an existing meeting in Skype for Business
- Kb 4095405 High memory usage and crash when you receive an HTML message in Skype for Business
- Kb 4095406 External user can’t sign in Skype for Business that uses TLS-DSK or modern authentication
- Kb 4095407 Splitter bar in a tabbed conversation window doesn’t show when DPI setting is larger than 100% in Skype for Business
- Kb 4095408 Repeated “You were added as delegate for” message at every logon in Skype for Business 2015 (Lync 2013)
- Kb 4095409 Searching chat room history by date returns incorrect results when the date format is other than US format (mm/dd/yy)

At about the same time any given Skype for Business deployment gains its second PSTN gateway / Session Border Controller, the old diagnostician in me wants a means to be able to directly send calls to each one individually. By being able to directly focus my outgoing calls on just one SBC I can confirm all sorts of things: that it’s talking to SfB OK, its carrier connection is working correctly, it’s sending the expected CallerID outbound to the PSTN, it’s handing calls from “unknown” calling numbers (foreign to the services attached to the SBC)… It’s also helpful if you want to test calls *in* to a different SBC, and you don’t want your outgoing call to muddy the logging captures on the SBC under test.
If your SBCs are in different states or countries you can usually take advantage of the Least Cost Routing (LCR) you’ve built into the deployment to achieve this – but what if they’re across town from each other in the same calling zone, or butting up against each other in the same rack in a load-sharing config? Enter “Direct Trunk Select”.

I recently had the opportunity to spend some quality time with “Pano”, Polycom’s meeting room collaboration interface, and I found it a really useful piece of kit.
What Is It?
Pano is an interface device that lets you share content from your PC, Mac or mobile device into a meeting or meeting room. You can do so wirelessly or via HDMI cable if you’re old-school.

I hit an expected snag recently where I wasn’t able to get an existing SfB 2015 Front-End pool to start after growing it from 1 to 3 servers. Coincidentally I’d performed this same job for another customer maybe a month prior and it had gone off without a hitch. Not so this time.
Try as I might, no amount of resetting the fabric with Reset-CsPoolRegistrarState was going to work; the pool steadfastly refused to start:
Start-CsPool : Please make sure at least 2 machine<s> are in running or starting state to achieve fabric network ring quorum from the following machine list. Also makes sure Windows Fabric Host Service is running on those machines.

Our March 2018 update nudges the server up from 6.0.9319.510 to 6.0.9319.516 and updates 7 components on my Standard Edition Front-End.
It doesn’t seem to be officially called CU7, but so far Martin and I are going with that. I’ll update the post if I’m advised to the contrary. CU6 HF2 it is, thanks Tim!
According to the kb, “This update enables Location-Based Routing to support the Skype for Business mobile clients”, but the last one said that too.
It also fixes the following issues:
- Kb4036626 Missing ApplicationOptions attribute in user object created by New-CsHybridApplicationEndpoint cmdlet in Skype for Business Server 2015
- Kb4078589 High memory usage on RtcHost.exe when you deploy Shared Line Appearance in Skype for Business Server 2015
- Kb4078588 Can’t sign in Skype for Business mobile apps after applying Skype for Business Server 2015 CU6
- Kb4078590 Calls to Mac fail when enhanced presence privacy mode is enabled in Skype for Business Server 2015
- Kb4078592 Push Notification not working for Skype for Business for iOS in Skype for Business Server 201
- Kb4078587 Voice settings are intermittently reset in Skype for Business on iOS and Android
