Certified SIP Trunk between MX-ONE and Lync

MX-ONE 4.1 Service Pack 3 is now listed on the Lync OIP page.
In August TekVizion Labs completed the certification testing for MX-ONE with Lync.

A comprehensive set of tests were executed in this independent laboratory in order to validate the interoperability between the systems. The test results concluded that the MX-ONE 4.1 sp 3 direct SIP implementation successfully passed the certification requirements according to Microsoft specifications.

The MX-ONE direct SIP integration with Lync supports the following scenarios:
  • Basic Call services between MX-ONE and Lync end-points over SIP trunks
  • Media Bypass (a.k.a. Direct media between MX-ONE and Lync clients)
  • Conference
  • Failover (to secondary Lync gateways)
  • Security (support for TLS/SRTP encryption)

Remote Call Control certification has not been completed as this requires some further development in MX-ONE. Even though not certifiable in the Lync certification program this feature might become available and supported by Aastra in a coming MX-ONE release.

Windows 8 is on it's way

Yesterday was the first day that Microsoft started to talk publicly about Windows 8. Truesec hosted a nice event here in Stockholm. We got to see all the past versions of Windows with some funny comments about each from a deployment and a developer perspective. Good job by Micke Nyström and Emil Kvarnhammar.

Starting with Windows 3.1 we got to see Win 95, WinNT, Win Vista, Win 7. During this nostalgia trip I remembered the first time I went to the Stockholm Globe area to see Windows 95 being launched, great event! But then I also remembered the network settings in Win95, configuring TCP/IP, and the modem icon - and then my skin started to itch in strange way. Things were not better before!

Then the program from the Windows 8 build conference in Anaheim was aired on a big screen. Windows 8 looks promising and here are some of the things shown and discussed that I remember.

  • Windows 8 will Boot faster
  • Save power by suspending applications not in focus
  • Save memory compared to Windows 7
  • Boot from 256 TB drives
  • Mount .vhd and .iso natively
  • Support for all Ipad features – multitouch, rotation, accelerometer, gyro
  • Support for an App store
  • New restore functions
  • Integration of settings, etc to Windows Live / Skydrive
  • Near Field Communications
  • Metro style GUI programs, and support for oldschool Win7 programs
  • Support Hyper-V
  • Improved taskmanager
  • Better support for multiple monitors
  • Can stop boot attempts from USB media?
    (Backtrack - get to work to "fix" this ASAP!)
  • Onscreen keyboard
  • Login by tapping a picture in a secret sequence, or by PIN?
  • Support for USB 3.0

Federation is fun!

After building a short list of Swedish organizations using Lync federation, I got in contact with Julian Bee from New Zealand. Quite funny that Lync federation would put me in contact with a guy from the other side of the world. Anyhow, Juilan managed to start what I had in mind much quicker than I, he now maintains a site called "Lync federation Directory" with the easy-to-remember URL of:

I will still maintain my list of Swedish organizations or organizations with business in Sweden, at this page: Svenska Lyncfederationslistan

It is cool to consider how this in the long run could create something like a PSTN for Lync clients. So this is what Mr. Bell and Mr. Ericsson must have felt like when their equipment started to spread around. Now this network has presence and video besides voice so it will be even nicer.

And now, for all you who have not done so yet...

Learnt about two cool new updates for Lync today...

Lync Social is the a free little application for Microsoft Lync that allows users to update their Lync, Twitter and LinkedIn statuses simultaneously. Looks something like this:

The other update is Lync for Mac

Lync for Mac 2011 offers Mac users integrated functionality for presence, instant messaging, conferencing and voice. Now Mac uses can set up Lync conferences from Outlook 2011 for Mac and use enterprise voice features.

Svenska Lync Federationslistan September 2011

Microsoft Lync har en fantastisk möjlighet till federering. Se närvaro, ring, ring med video, skicka filer och dela applikationer över företagsgränserna! Organisationer som federerar måste ha en Lync Edge server och DNS posten ”” registrerad i det publika DNS systemet. Det går även att styra vilka andra organisationer man vill federera med, men - information wants to be free – så öppna upp!

Hör av er till mig om ni vill vara med på listan, eller om jag skall plocka bort er, eller ändra någon uppgift. (

When I am busy I am busy and do not disturb me!

Lync handle the concept of busy differently than many traditional IP-PBX systems. Is it better or not? I do not personally know and I guess that it largely is a matter of taste and personal preference.

When busy in a call in Lync you could still get notifications popping up as a toast on your computer screen, not to intrusive and could easily be handled by most users. But if you also have parallel ringing configured to your cell phone it would also start to ring while you’re in a call, not to nice...

Another scenario where the Lync version of busy might fall short would be in a PBX integrated environment and where you have a serial call list, e.g. call first my PBX phone and then my Lync client and if I do not answer send the caller to my voice mail box. Now if Lync did not hand back a busy tone to the PBX you could end up in a scenario where you are busy on the phone in Lync, another important customer calls and he will not even reach your voicemail box. Hmm...

So we can see that in some environments there is a need for Lync to adapt to an old-fashioned way of handling busy.

Enter the Busy-on-busy software from the good people at Unify Square.

I have tested this little piece of software and it works like a charm! It is easy to install and it is easy to configure the system user-by-user as to if they are going to have busy-on-busy or not.

To install, you simply run a setup.msi on all the Lync front-ends, and the register the software:

C:\Program Files\Unify Square BusyOnBusy>BusyOnBusy.exe /register

Registering the BusyOnBusy Server Application.....
Successfully registered the BusyOnBusy server application

Then you simply use the .exe file with a sip address to configure which users that should get a busy tone.

C:\Program Files\Unify Square BusyOnBusy>BusyOnBusy.exe /multiplecalls:block /

Certificate SerialNumber is: 62C85547000000000005
Configuring SipUri:, Multiplecalls: block
Configuration for was modified.

Looking at the illustration above we can discuss three scenarios which will be different if the user "Mattias Kressmark" have busy-on-busy turned on.

1. An external call to a PBX-homed DID number which is configured with a serial call list. In this case the incoming call would ring the PBX phone for x number of seconds, move on to the Lync "extension", then get a busy tone by the busy-on-busy tool, and then go to the voicemail system connected to the PBX.

2. An external call comes in and Mattias Kressmark is not answering anywhere, then the caller would end up in the voicemail box. (Yes, I do know about Exchange UM but just because we have two call managers we do not want two voicemail systems as well.)

3. An internal user - Isabella - calls Mattias who is in another call and she will then see the following message in the Lync client:
