Updated: iOS 9 and Lync 2013 sign in problems


iOS 9 is here! And like most iPhone owners I downloaded iOS 9 yesterday and installed it. If you or your Lync users haven’t done this already you might be in for an unpleasant surprise.

After the install was done I launched Lync and and hit the sign in button. I was greeted with the following error mesage.


After doing all the normal troubleshooting I still couldn’t find the reason for the error.

Thanks to Guy Bachar’s post I first of all realized that I wasn’t alone in having this issue. Turns our that for some reason; if your regional setting on iPhone doesn’t match your iPhone language you can’t sign in to Lync if you are on iOS 9.

This worked fine in iOS 8 and to me it’s really frustrating. I prefer to have my regional settings set to Swedish to get date, currency and all that in…

“The odd call drops” of the Mediation Server

“The odd call drops” of the Mediation ServerStandardI had a very annoying issue lately when an installation of a new gateway resolved in some calls (specifically to US numbers) dropped by the Skype for Business mediation server saying “A call to a PSTN number failed due to non availability of gateways.”The cause, according to the mediation server, was that “All gateways available for this call are marked as down“, and the resolution, surprisingly, was to “Verify that these gateways are up and can respond to calls.”It seemed funny, because all other calls were successful, I have not exhausted the available PRI channels I had, the gateway didn’t seem to lose connectivity for a split second and SIP options are accepted and replied to on both ends.Looking further at the Lync Monitoring Reports, I noticed the following:Reported by Client12000; reason=”Routes available for this request but no available gateway at this point”Reported by Server12000; reason=”Routes available for this request but no available gateway at this point”I went to the gateway (AudioCodes M1000B) for answers and the logs were showing something very weird;Every call starts with the same flow:Flow1The mediation server sends a SIP Invite that will normally be answered immediately by the gateway with a “100 Trying”. This, for me, will close the deal on the “Gateway no responding” – this is a great response if you ask me.The next phase would be the gateway immediately sending a “PSTN Place call” to the PSTN, hopefully receiving a “Proceeding” instantly from the PSTN, meaning so far we’re fully communicating. So for the time being I’m not really buying what the Lync mediation server is selling.Looking further at the logs, I see the following strange behaviour:As I’m still waiting for the PSTN to connect the call (this would normally be a “PSTN Call Alerting” message), I see that the mediation server decided to abandon ship!This is what I see in the logs:WrongWithin 10 seconds after initiating the call, the mediation server will send a “Cancel” request to the gateway and will terminate the call:19:25:49.640 [S=660986] [SID:1327438938] INVITE sip: 353857560598@;user=phone SIP/2.0 19:25:49.729 [S=661027] [SID:1327438938] SIP/2.0 100 Trying 19:25:49.730 [S=661035] [SID:1327438938] ( lgr_psbrdif)( 656225) pstn send –> PlaceCall19:25:50.087 [S=661039] [SID:1327438479] ( lgr_psbrdex)( 656229) pstn recv PSTNDisconnectCallClearly, the gateway is available and responding, but the mediation server is somewhat impatient.Doing a bit of digging around, it appears there’s a setting for this.

The stats helper monkeys prepared a 2015 annual report for this blog.

Here’s an excerpt:

A San Francisco cable car holds 60 people. This blog was viewed about 1,700 times in 2015. If it were a cable car, it would take about 28 trips to carry that many people.

Lync 2013 – High Performance App Sharing

How you can enable higher resolution in screen sharing.
Instruktioner för hur du får högre upplösning och skärmuppdaterin med Skype for business

D(one) IT

After installing Lync Server 2013 Cumulative Update 3 – October 2013 (, the CSClientPolicy now exposes two new parameters for High Performance Application Sharing.


Looking at the Parameters for Set-CSClientPolicy on TechNet (

  • EnableHighPerformanceP2PAppSharing: “When set to True, allows a peer-to-peer application sharing session to exceed the maximum frame rate of 2.5 frames per second. The default value is False.”
  • EnableHighPerformanceConferencingAppSharing: “When set to True, enables high performance application sharing in conferences. This improves the performance of application sharing, but, at the same time, means fewer resources are available to other processes.”

Enable High Performance functionality:



Peer to Peer Desktop sharing of a YouTube video, both clients external via Edge (start both videos below at the same time to compare).

  • EnableHighPerformanceP2PAppSharing: False (Default)
  • EnableHighPerformanceP2PAppSharing: True

With High Performance enabled the frame rate differences were noticeable, video playback was more fluid. Keep in mind bandwidth…

Run this tool from Lync Management Shell or Skype for Business Management Shell.

Note you will need to run this tool with Local Admin permissions (You will be prompted for elevation automatically if not) and you must have ADDS RSAT installed so you can use the Active Directory PowerShell Module.
You will be asked to provide an Active Directory Group name. Type the Display Name of the group, the tool will reply with the CN of the group, confirming you chose the right group:

Choose Group

Then choose the type of policy (or dial plan) you want to assign this group, there are 14 options:
1     Voice Policy
2     Client Policy
3     External Access Policy
