Cisco Quality Manager 11.5.1 SR6 with Microsoft SQL Server Express 2014

After smashing around in SQL for too long to get the basic QM communication to work (shown below), I found that Andrzej Gołębiowski  documented the same requirements at http://blog.citrix24.com/configure-sql-express-to-accept-remote-connections/ back in 2014.  He has some additional detail regarding SQL versions, service usage and best practices there. I encourage you to check it out.  My info is limited to the basics required to get QM running on a rainy Tuesday morning.

I was recently tasked with spinning up a Cisco WFO QM / Quality Manager instance for a demo to be run out of our own office.  Given it was only a demo I used a small stand alone OVA for QM (version 11.5(1) currently available here),  a trial version of Windows Server 2012 R2 ( https://www.microsoft.com/en-US/evalcenter/evaluate-windows-server-2012) and a  version of MS SQL Express 2014 (https://www.microsoft.com/en-US/download/details.aspx?id=42299).

When downloading MS SQL Express, choose the ExpressAndTools 64BIT\SQLEXPRWT_x64_ENU.exe version.  You may have to scroll down a bit on MS's page to find it.  Having the extra administration tools available up front is worth the extra few minutes it takes to download the media.

If you are not typically administering MS SQL servers, you will need to perform some SQL setup that is not documented in the Cisco QM install information.

You will need to enable TCP connections to SQL server.

  • Run Microsoft SQL Server Management Studio.
  • Right Click on your SQL server and choose Properties.
  • Verify Allow remote connections to this server is checked.




  • Run SQL Server Configuration Manager.
  • Expand SQL SErver Network Configuration and select Protocols for SQLEXPRESS
  • Right Click TCP/IP and choose Enable.

You will need to set SQL Server to listen on a static port.

  • Still in SQL Server Configuration Manager...
  • Expand SQL Server Network Configuration and select Protocols for SQLEXPRESS
  • Right Click TCP/IP and choose Properties.
  • Choose the IP Addresses tab.
  • Scroll down to the IPAll section.
  • Remove the value in TCP Dynamic Ports.
  • Enter 1433 as the TCP Port


  • Still in SQL Server Configuration Manager...
  • Choose SQL Server Services.
  • Right Click SQL Server (SQLEXPRESS) and choose Restart
  • After the server is restarted, make note of the Process ID.
  • From the windows CLI, run netstat -ano | find /i "<your process ID>" 
The listening port should now be 1433.
 You will need to turn on the SQL Server Browser Services

  • Still in SQL Server Configuration Manager
  • Choose SQL Server Services.
  • Right Click SQL Server Browser and choose Properties.
  • On the Service tab,  change the Start Mode to Automatic.
  • On the Log On tab, choose the Start Button.




Assuming you've previously followed the Cisco QM Installation guides, you should now be able to have QM make successful connections to SQL server.

MS Windows 10 desk top icons detail and list view


Edit: As of May 19, 2017 this feature seems to have been broken by some Windows updates. Crl Shift 1 - 4 resize the icons but I can no longer get them to appear in "ListView".

For years I've had a small program running at startup on my Windows 7 based PC.  It would convert the icons and text on my Win7 desktop to what look likes the list view in Windows Explorer, allowing me access to dozens of frequently used shortcuts, files and folders there without consuming much real estate or requiring flipping between my applications and my desktop view.

My internal IT team was kind enough to upgrade my laptop recently and I was happy to find Windows 10 now has this feature built in.

To emulate my old experience, while your desktop has the focus, press Ctrl Shift 5.


If you'd like additional detail, Ctrl Shift 6 changes the view what appears to be the Explorer Details view.

It seems Ctrl Shift 0 through 9 may provide easy switching between various views.

Cool.  Thanks Windows 10.

2N Helios IP Force and CUCM IP Phone Services

Client acquired several 2N Helios IP Force door phones with integrated cameras with the intention of using them to open door locks nearby.  In addition to the normal DTMF triggering method, they wanted to have the ability to unlock them without calls to the door in progress.  The plan was to use the Helios automation features to respond to CUCM device Service URL button pushes.

The Helios units require the "Enhanced Integration" or "gold" license to use the automation features.
Navigate to System | License and check the License Status area to confirm you have it available.


In my environment we will be using the first relay on the Helios device to trigger an electronic door lock.  We need to flip the Helios relay for 5 seconds, which will unlock the door, and then flip it back to allow the lock to re-engage.

Navigate to Hardware | Switches and the Switch 1 tab.
Confirm "Switch Enabled" is checked.
Confirm Switch Mode is Monostable.  This means it will flip on and stay on for X amount of seconds, then flip off. 
Set Switch-On Duration to however many seconds you need the switch on.
Assuming you have already wired the door lock to activate via this switch, you can press the Test the Switch button here and verify it works.


Navigate to Services | Automation
Pick a function tab and confirm "Function Enabled" is checked
On row ID 1, change OBJECT TYPE to Event.HttpTrigger.  On the same row in the PARAMETERS field enter "Name=opendoor" 

 This now defines a trigger for a function that the Helios IP Force will perform when it handles an HTTP request.  The word "opendoor" on the HTTP URL is what triggers this particular function.

Now make your function actually do something.  Our something is pretty simple.

On row ID 2, change the OBJECT TYPE to Action.ActivateSwitch.  On the same row in the PARAMETERS field enter Switch=1;Event=1.

The Event=1 parameter means do something when the event on row 1 happens (our opendoor HTTP trigger above).
The Switch=1 parameter means do something to the switch number 1 on your Helios unit (different units may or may not have the same number of switches).
The Action. ActivateSwitch is similar to pressing the Test the Switch button above.  Depending on how your switch is configured (i.e. Monostable) defines what ActivateSwitch actually does. 

Again, because the HttpTrigger (opendoor) happens on row one (ActivateSwitch and Event=1), switch number one is turned on (ActivateSwitch and Switch=1) for five seconds (Switch-On Duration) and then turned back off (Switch Mode is Monostable).

In a browser enter http://<IP address of Helios endpoint>/enu/trigger/opendoor

Navigate to Status | Events to see the Helios responding and check your work.  You should see switch=1 changing to true and then five seconds later to false.


If this works, you can now have CUCM users (receptionists, safety staff, etc.) perform this function from a button on a phone.

In CUCM navigate to Device | Device Settings | Phone Services
Add a new service using the Service Category "Web Link" and the Service Type "Standard IP Phone Service"


In CUCM navigate to Device | Phone and find the phone that will press a button to open the door.
Choose Subscribe / Unsubscribe Services from Related Links.  Choose the Service you created above.



On the same device, add a Service URL button and configure with the subscribed service.



Pressing that button should now trigger the HTTP Event and function that turns on the Helios switch 1, opening the attached door.

Cisco Unity Connection InitMMAppletInstance failed to get instance Failed to record name Unable to save recording due to SSL Certificate error

Using the Java based Media Master control in Unity Connection to record or upload greetings has historically been a disaster.  To complicate the issue, browser vendors are now dropping support for the Java plugin entirely.  What this means is if you are still supporting an older version of Unity Connection, what used to be a completely unreliable method to manage greetings is now impossible from an up to date PC / browser.

As a work around,  you can still get your hands on old versions of Firefox that will support old versions of the Java plugin.

I would suggest using an Extended Support Release rather than experimenting with older, possibly buggy, possibly insecure versions.  The Mozilla Firefox 52 32-bit ESR / Extended Support Release as of today April 20, 2017 continues to support NPAPI based plugins (i.e. Java). You can download that version here: https://www.mozilla.org/en-US/firefox/organizations/

Remove any version of Firefox you have and install this version.

The Exception Site List feature of the Java plugin was introduced in Java 7 Update 51. You'll need that feature to get the Media Master to work but you need to stay away from updated Java plugins.

You can download the Windows x86 Offline Java installer for Java 7 Update 51 here:  http://download.oracle.com/otn/java/jdk/7u51-b13/jre-7u51-windows-i586.exe  (you'll need to create an account).  If you don't trust me to access the EXE directly, the official Java archive page is here:  http://www.oracle.com/technetwork/java/archive-139210.html  You can start there and find it yourself. 

- - Un-install all your other versions of Java and install this one.
- - Go to Control Panel | Java 32-bit | Security and set your security level to medium.
- - Go to Control Panel | Java 32-bit | Security | Exception Site List and add you Unity Connection Publisher and Subscriber.  Use the format https://:8443 and https://:443


You should now be able to run the Unity Connection Media Master (at least back to version 8.6) in Firefox, play, upload and save greetings.  You may still be prompted a handful of times to allow Java to run, and possibly have to save the greeting multiple times in Unity Connection after SSL pop-ups, but it works.

Trust me.  I did it yesterday. 

Don't forget to delete this version of Java and Firefox before your IT security team freaks out.
