Have your Microsoft Teams meeting call you back

If you’ve got a Skype for Business Audio Conferencing license, you’re now able to dial out to your own phone number from a current meeting. This allows you to transfer meeting audio to your phone if you’re having network problems, need to get in the car or on a slow connection.

Click the “i” icon on top of the right screen.

Here you can type in your own phone number.

If the call is placed succesfull, a checkmark will appear.

Mute someone in a Microsoft Teams Meeting

Microsoft has released (Januari 17) some new features to the Microsoft Teams client.

Mute someone in a meeting

Mute individual meeting participants straight from the meeting roster to cut down on background noise. If someone has been muted, they’ll get a notification letting them know. They’ll be able to unmute themselves if they need to chime in.

Mute everyone in a meeting

If you ever need to mute all the other participants in a meeting, head to your meeting roster and select Mute all. Each individual will get a notification and be able to unmute themselves if they need to.

Eventid 25073 Enable comfort noise on your trunk (Audiocodes)

Hi All,

First blog of the year, officially not allowed anymore but best wishes for all of you!

After going through some event logs on Frontend servers i came across this warning:

The Mediation Server service has received a call that does not support comfort noise. This event is throttled after 5 calls from a single Trunk peer.

The Mediation Server service has received a call that does not support comfort noise from the Trunk, SBC01.domain.com;trunk=SBC01.domain.com
Cause: The Trunk does not support comfort noise.
Please ensure the comfort noise option on the Trunk has been enabled.

For the ones who are not familiar with the term, Comfort noise (or sometimes called comfort tone) is synthetic background noise used in communications to fill the artificial silence in a transmission resulting from voice activity detection or from the audio clarity of modern digital lines. If want to read more about Comfort Noise i suggest you to the following pages Wikipedia, and RFC3389.

I’m running a Audiocodes Mediant 1000 for this customer, so let’s fix this warning.

Login to your Audiocodes Mediant and go to Setup, Signaling&Media, Media, RTP/RTCP Settings

Make sure you have enabled:

  • RFC 3389 CN Payload Type
  • Comfort Noise Generation Negotiation

Then go to Setup, Signaling&Media, Coders & Profiles, Coder Groups

Enable the Silence Suspression for all of your configured coders.

That’s All!
