Using Windows Powershell to Accsess Cisco Meeting Server Rest-API

Using google Postman to access Cisco Meeting Server Rest-API is the most common way to configure the server.
But it can be time consuming with lot's of cut and paste of ID's and such.

So I though I'd try to acess the CMS api via powershell.
It was actually surprisingly simple.

First I found a function to ignore self signed certificates.

function Ignore-SelfSignedCerts
{
    try
    {        Write-Host "Adding TrustAllCertsPolicy type." -ForegroundColor White
        Add-Type -TypeDefinition  @"
        using System.Net;
        using System.Security.Cryptography.X509Certificates;
        public class TrustAllCertsPolicy : ICertificatePolicy
        {
             public bool CheckValidationResult(
             ServicePoint srvPoint, X509Certificate certificate,
             WebRequest request, int certificateProblem)
             {
                 return true;
            }
        }
"@

        Write-Host "TrustAllCertsPolicy type added." -ForegroundColor Whi…

Chrome not working with Cisco Meeting Server

After some point  in February there seems to have been an update in OpenRTC that causes WebRTC to fail in Chrome browser when you try to join a Space in Cisco Meeting Server 2.x.x.
Both 32/64 bit versiouns of chrome does not work.
After you enter the conference id the browser just hangs in the "connecting" mode for about 25 seconds before you are presented with the login page again.
Seems like Firefox is the only browser that currently works with Cisco Meeting Server 2.x.x.

Have not found a workaround pr date other than using Firefox.

Mini computer and conference speaker all-in-one from HP

Image
This is one of the coolest concepts I've seen this year. HP has made a modular concept called Elite Slice that no more than 16,5x16,5cm.
The modules can be stacked on to of each other and it looks really great.
This is basically a mini-computer, speaker (Bang&Olufsen), optical unit, wireless charging pad and more integrated in a stackable modular system.
This reduces the need for cables and contents can be shared via wifi.
Best off all it according to HP integrates well with Skype for Business.
It even has a custom cover to fit Skype for Business usage.

Why you should never route internal Skype4B media traffic externally.

This puzzles me.
I have on several occasions been called in to solve issues with varying audio- and video quality at customers with Lync 2013 and Skype for Business deployed on premise.
After som tracing of media flow I have found that some of these for some reason has chosen to route all internal sip traffic towards the external interface of the edge server.
This all would still work better if media was able to route peer to peer between the clients.
In many cases this is not so.
The internal networks does not allow this so media is routed through edge.
This causes severe jitter and increases round trip significantly.
Video will appear as lagging and audio will be distorted or clipping.
The Skype4B quality indicator in the client will turn orange or red indicating that something is wrong.
Furthermore some equipment like Polycom phones and similar will not enjoy getting a certificate form the external interface of the edge server.

So what I do is usually to change/add the internal DN…
