Join meeting audio from

 

 

Registry locations	HKCU\Software\Microsoft\Communicator\JoinAudioConferenceFrom
Allowed registry values	0: Do not join audio 1: Join meeting audio using Lync
Registry value type	REG_DWORD
Default setting	Not present (join meeting audio using Lync)

 

By default, any time you join a meeting using Microsoft Lync a dialog box similar to this will pop up asking which audio source you want to use for the meeting:

 

 

Note. What if you don't want to see this dialog box each time you join in a meeting? In that case, see the article Prompt me before joining to confirm or select another audio source .

 

By default Lync preselects the option Use Lync (integrated audio and video) . But what if you'd prefer that Lync preselect the option Do not join audio? (Sorry, but the answer is no: you can't preselect the Call me at option.) That's fine; you can select your default audio source from the Options dialog box by selecting the desired value from the Join meeting audio from dropdown list:

 

 

 

 

But you know what? You're right: dropdown lists are nowhere near as much fun as managing settings via the registry and, preferably, by using a Windows PowerShell script. To that end, the following PowerShell script retrieves the current value of the HKCU\SOFTWARE\Microsoft\Communicator\JoinAudioConferenceFrom registry value on the local computer. If you'd prefer to retrieve this value from a remote computer, simply set the value of the variable $computer to the name of that remote computer. For example:

 

$computer = "atl-ws-001.litwareinc.com"

 

Here's the script for retrieving the JoinAudioConferenceFrom value:

 

$computer = "."

 

$registry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("CurrentUser", $computer)

$key = $registry.OpenSubKey("SOFTWARE\Microsoft\Communicator", $True)

 

$value =$key.GetValue("JoinAudioConferenceFrom",$null)

if ($value -eq 1) {$value = "Lync"}

if ($value -eq 0) {$value = "Do not join meeting audio"}

Write-Host "Join audio conference from: $value"

 

Even better, here's a script that sets the value of JoinAudioConferenceFrom. In this script, the script sets the default audio source to Lync; that's done by setting JoinAudioConferenceFrom to 1. To set the default audio source to Do not join audio, set JoinAudioConferenceFrom to 0:

 

$key.SetValue("JoinAudioConferenceFrom",0,"DWORD")

 

Here's the script:

 

$computer = "."

 

$registry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("CurrentUser", $computer)

$key = $registry.OpenSubKey("SOFTWARE\Microsoft\Communicator", $True)

 

$key.SetValue("JoinAudioConferenceFrom",1,"DWORD")
