Lync 2013 / SfB 2015 Client Security Update – March 2017

By my reading it’s been 5 months since our last security update to the Office 2013-based Lync/SfB client, and this one takes us from 15.0.4903.1001 to 15.0.4911.1000. It’s listed as Critical as there’s the risk of remote code execution.

Kb 4013075 “This security update resolves vulnerabilities in the Microsoft Graphics Component on Microsoft Windows, Microsoft Office, Skype for Business, Silverlight and Microsoft Lync. These vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document.

To learn more about the vulnerability, see Microsoft Security Bulletin MS17-013.

What’s Fixed

This security update also contains fixes for the following nonsecurity issues:

  • Kb 4013150 EWS connection issue after migrating mailbox to Exchange Online Dedicated vNext in Skype for Business 2015 (Lync 2013)
  • Kb 4013149 Update to support dedicated URLs of Black Forest and ITAR in Skype for Business 2015 (Lync 2013)

Installing the Sonus "SWe Lite"

Sonus announced the SWe Lite at Ignite in the US late last year and we’ve been anxiously awaiting its arrival. Well, IT’S HERE!

The SWe Lite is the “Software Edition” of Sonus’ well-established Enterprise-grade Session Border Controllers, the SBC 1000 and SBC 2000.

I’m particularly impressed with the look and feel. At a quick glance it’s indistinguishable from a 1k or 2k:

SWeLite-ChannelMonitor Calls

The GA build supports up to 100 SIP calls, 25 transcoded or encrypted sessions and a call setup rate of 10 calls per second. It’s a faithful port of the SBC we’re familiar with, so includes the bulk of the features we’ve come to rely on for years including the powerful AD integration & the invaluable real-time channel monitor (shown above).

Notably absent is inbuilt Music On Hold, although we’re assured that’s coming soon. Check out the datasheet or the page “Functional Differences Between SBC Edge and SBC SWe Lite” for more of the engineering and feature specifics.

Sonus is letting an “unlicenced” SWe Lite carry up to 5 ordinary SIP calls or 3 encrypted/transcoded calls – more on that below. In the screen-grab above I’ve established 3 calls successfully over TLS to Skype for Business and a failed fourth call attempt is what generated the “Failed to acquire licence” you can see in the Alarm View.

SfB "Cannot park call right now"

I’m on record saying Call Park is my favourite PABX feature, and its great that we have it available to us in Skype for Business.

“Parking” a call transfers it off to a “holding bay” where the caller hears MOH until such time as someone retrieves the call. If they’re left waiting too long a timeout returns it to the party who parked it.

In SfB you initiate the process by clicking Transfer, then selecting “Park the call”. All going well the call vanishes to places unknown and is replaced with a message to say “the call is parked”, and a special “Orbit” number you – or anyone – can dial to retrieve it.

Its utility eclipses that of a simple call transfer when you don’t actually know where you need to transfer the call to, or if you want to securely (or secretly) manage the process. It’s the perfect answer for a range of scenarios:

  • The attendant can park a call for someone and then over the Public Address system announce who the call’s for and at what call park “Orbit” number they’ll find it.
  • In the absence of a PA system anyone can park a call for someone, jot the Orbit number on a post-it note and personally seek out the recipient, thrusting the retrieval code into their hand.
  • It’s a more relaxed approach to an “announced (supervised) transfer”: park the call, IM the recipient and type the park location into the IM. When they’re composed and ready to take the call they retrieve it from where it’s parked.
  • Staff in open-office environments can use it to easily move a sensitive call from their shared workspace to the privacy of a meeting room. The advantage of Call Park over Transfer in this scenario is that they need not know the name of a nearby room or even if it’s occupied: just park the call and wander around until you find a safe space.

Installing SEFAUtil Server

Tips, tricks and traps

There’s an old joke that goes “Q: Why do people take an instant dislike to <InsertNameOfUnpopularPolitician>?” “A: It saves time”. And so it is with SEFAUtil.

Without doubt SEFAUtil is an indispensable utility. “Secondary Extension Feature Activation Utility” – to give it its full name – ships in the Lync and Skype for Business “Resource Kit” (“ResKit”) download pack. When correctly integrated into the topology it gives support staff the ability to query, set and cancel all manner of call-forwarding and team/delegation settings from the comfort of their cube, without needing to visit the user or reset their AD password in order to do it remotely (after signing in as that user). It’s a godsend when someone goes on leave unexpectedly or has a catastrophic PC failure with an urgent incoming call pending, and as equally helpful when configuring the settings for executives and other ‘sensitive’ users.

VVX – Missing files, config reverted

This error pops up from time to time with the Polycom UCS family of devices (VVX, Trio & SoundPoint) and it’s usually easily resolved.


Whilst the phone won’t tell you what the problem is – it doesn’t name the file(s) it can’t find – your provisioning server is likely to hold the answer.

In this example, the error is here in plain (hind)sight:


Can you see it? Here’s how to find it.
