After some diging in to this problem i found some people having same issues with other Microsoft products. Last March Microsoft released the CredSSP update and this prevented connecting to vulnerable systems using older authentication methods.

Problem

I came across a problem that it was not possible to change the IP address of the MediaPack 112.

The IP Address, subnet and default gateway are greyed out as you can see in above image.

Solution

Go the the webinterface (System, Management, Telnet/SSH Settings) and enable SSH access.

Use PuTTy to connect to the current IP Address of the MediaPack. Use the default credentials if not changed: Admin - Admin

Skype for Business Licensing Guide

2018-03-20 4 min read Skype for Business Skype for Business Online Erwin Bierens

Lately i’m getting a lot of questions about licensing for Skype for Business Server and Online. So i want to try to explain what kind of licenses you will need to have in the different scenarios.

Is E3 license enough for Skype for Business Server 2015 with Enterprise Voice?
Do we need PSTN Calling plan with the use of Skype for Business Server 2015?
Do we need to have Phone System (formally Cloud PBX) license when using Skype for Business Server 2015 in Hybrid mode?
Do we need a server license to use Skype for Business?

To make one thing clear, Client Licenses are required to access all Skype for Business Online (Office365), Hybrid scenario’s and Server (On-Premises) features.

Skype for Business Online Call Queues: Agent Opt In/Out

2018-01-16 2 min read Skype for Business Erwin Bierens

Last night Microsoft announced and published the Agent Opt In/Out feature to Skype for Business Online.

This update allows Admins to grant Call Queue Agents an ability to Opt In and Out from taking calls from a particular Queue at will.

For all newly created Call Queues, Agent Opt In/Out option will be enabled by default. For pre-existing Call Queues, Admins will need to enable this feature manually.

How to enable Agent Opt Out (Admin)

First login to the Office 365 Admin panel Link
