TsooRad is a blog for John Weber. John is a Skype for Business MVP (2015-2018) - before that, a Lync Server MVP (2010-2014). My day job is titled "Technical Lead, MS UC" - I work with an awesome group of people at CDW, LLC. I’ve been at this gig in one fashion or another since 1988 - starting with desktops (remember Z-248’s?) and now I am in Portland, Oregon. I focus on collaboration and infrastructure. This means Exchange of all flavors, Skype, LCS/OCS/Lync, Windows, business process, and learning new stuff. I have a variety of interests - some of which may rear their ugly head in this forum. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. One of these days, I intend to start teaching. The opinions expressed on this blog are mine and mine alone.


AudioCodes Updates phone firmware

AudioCodes has just released a firmware update for their popular 4xxHD series handsets.

An updated firmware version for AudioCodes’ Lync-compatible 400HD Series of IP Phones is ready. Herewith is a general outline of things, with maybe a few comments from me.

Better Together over Ethernet (BToE) PC application version was not updated in this release:

Firmware Version name:

  • UC420HD_2.
  • UC430HD_2.
  • UC440HD_2.

This version introduce several new features:


USB Headset beta

(supported only by 430HD and 440HD IP Phone models). The following USB headsets are supported:

<jmw> It’s about time! Feature parity with the competition is a worthy goal.  As soon as I have another 430 or 440 I will try out other headsets.

  • Jabra UC-150
  • Jabra Speak 510+
  • Jabra Speak 410
  • Jabra PRO 9470
  • Microsoft LX-3000
  • Plantronics C-310M
  • Plantronics C-320M
  • Plantronics HW720


Block Sign-Out for Common Area Users

Administrators can now disable end users from signing out of a common area phone. To support the feature, the new configuration file parameter, voip/common_area/enhanced_mode has been added. The default is 0 (disabled). When enabled, the Sign out soft key is not displayed on the LCD.



<jmw> YES!  Finally!


through Web

A new Web page has been added that allows users to sign-in through the phone's Web-based management interface.

<jmw> This could be set in earlier builds, but that did not work as well as this new method.  I like it much better.  The functionality is much improved, and when tied to the blocking of the Common Area User concept removes a goodly percentage of help desk calls asking how to log in to the phone.


And then there is this little gem in the “new features” section of LTRT-08267…


AudioCodes' enterprise voicemail servers are now supported as an alternative option to Microsoft Exchange Server.
<jmw> We are checking on what exactly this means.  Gotta love those developers who work up something but never tell anyone about it.

There is a blurb in the same LTRT that I found: 

Voicemail is supported for Microsoft Exchange Server 2010 and later. A version supporting Voicemail for Microsoft Exchange Server 2007 will be provided upon a specific request.

But I don’t this is meaning the same thing.  I think this means accessing the local Exchange Server user mailbox to listen to voice mail. Again, I am working with an internal AC engineer to determine what the “new feature” is meant to be.


Better Together over Ethernet (BToE) PC Application (1.0.20):

  • Support for Microsoft Windows 10
  • Compatible with Skype for Business
  • GUI enhancements

Disable Local Three-way Conferencing

Administrators can now disable the local three-way conference capability. By default (when not in BToE pairing mode), when phones are in call state, the phone's LCD displays options to enable local three-way conferencing. To support the feature, a new configuration file parameter, lync/local3wayConf/enabled has been added.

Allow Users to Display Phone or Extension Number

Administrators can now allow users to define whether to display their telephone or extension number on the phone's LCD. This is only possible if the enterprise's Active Directory includes both telephone and extension numbers. To support the feature, the new configuration file parameter, lync/sign_in/line_type_display/ext has been added. The default is 1 (extension number is displayed).

Core Dump file generation can be enabled and downloaded through the phone's Web-based management interface.

For the complete list of new features & known limitations, please refer to LTRT-08267 400HD Series of IP Phones for Microsoft Lync Release Notes Version 2.0.11.pdf.

Clearly, at least two of the “new” items will require that you prepare configuration files for your handsets.  But that is trivial, IMHO.  You already have your TFTP ready to go, right?  Aren’t you just dying to try out this new firmware?  You can get it here!
