Parameter/Property Name

Allowed Values


This is a per-organizer setting.

· TRUE: IP audio can be used in a meeting. This is the default value.

· FALSE: IP audio cannot be used in a meeting.

Lync Server Control Panel Equivalent Setting : Audio/Video

Do you believe that silence is golden? If so, then we've got a Lync Server conferencing policy setting made just for you.

By default, Microsoft Lync allows you to add IP audio to any online meeting; that simply means that you can use the sound capabilities built into your computer to talk to other people in the meeting. It's just like talking on the telephone, except that you don't actually need a telephone.

For most organizations that's a pretty good deal; that explains why IP audio is allowed by default. However, it's possible that, in other organizations (especially those with limited bandwidth), allowing IP audio in a meeting isn't considered such a good deal. (After all, audio traffic is going to have travel on the same network as the rest of your network traffic.) If that's the case, then we've got a Lync Server conferencing policy setting made just for you.

Oh, right: we said that already, didn't we? Well, here's the setting in question: AllowIPAudio. When AllowIPAudio is set to True (the default value), then you can enable IP audio by selecting Use Lync (integrated audio and video) when you start a meeting:

Alternatively, you can add IP audio to a conference at any time simply by clicking the Call menu in the Conversation window:

Pretty cool, huh?

By comparison, if AllowIPAudio is set to False you won't be prompted for the audio source when you join a meeting. (Actually, you might not be prompted anyway, depending on how you've configured Microsoft Lync. But that's another story for another day.) In addition, the Call menu will no longer be available in the Conversation window:

Incidentally, here's how you disable IP audio in a meeting:

Set-CsConferencingPolicy –Identity global –AllowIPAudio $False

And here's how you enable IP audio:

Set-CsConferencingPolicy –Identity global –AllowIPAudio $True

It's important to keep in mind that the AllowIPAudio setting is a per-organizer setting: that means that it applies to the person who organized the meeting (and therefore to everyone else in that meeting). For example, suppose we have two users and two different conferencing policies:


Conferencing Policy


Pilar Ackerman



Ken Myer



If Pilar Ackerman organizes a meeting then no one in that meeting will be allowed to use IP audio. Why not? Because Pilar's conferencing policy prohibits IP audio and, as the meeting organizer, her conferencing policy is the only one we care about. (Well, when it comes to IP audio, anyway.) And what if Ken Myer organizes a meeting? In that case everyone in the meeting will be allowed to use IP audio. Why? That's right: because Ken's conferencing policy allows people to use IP audio in any meeting Ken organizes.

Oh, and here's something else to keep in mind: AllowIPAudio can be used to disable IP audio, but it doesn't prevent people from using telephones and dial-in conferencing to add audio to a meeting. If you want to eliminate audio altogether (or at least Lync Server-managed audio) then you should set the EnableDialInConferencing property to False as well.
