Skype for Business Audio Conferencing



Skype for Business Audio Conferencing (Public Switched Telephone Network) conferencing allows at least one participant to dial into the audio portion of a Skype meeting.  This is also commonly referred to as a dial in conference, or a conference bridge line. This functionality also allows you to dial a phone number to add it to an existing meeting.



How complex is this to use?

When the license is enabled, the organizer’s meetings will have a dial in number and conference ID added to the meeting information.

What are the benefits for adding this?

  • This allows organizers to host a meeting where users can join any Skype for Business meeting via Skype client, or dial in via phone (or combination)
  • There are no more issues with scheduling an “online meeting” then also trying to manage a dial in conference bridge line
  • Many times dial in meetings often turn into needing to share information (share screen, documents, IM, etc.)
  • Organizers (or notetakers) can easily see who has joined the call (limits the “Who just joined?” and rollcall at the beginning of meetings)        

What phone number do we use?

The dial in number is issued by Microsoft, and is a shared phone number.  The phone number has an area code of 470.

(470) is the default area code used by Emory’s Skype for Business dial in conferencing. This is a newer area code that is local to Metro Atlanta.

Each meeting is granted a unique conference ID.  The meeting organizer with the Skype for Business Audio Conferencing will be issued an organizer code once the license is assigned. 

What is the conference ID, and can I have my own?

The conference ID is randomly generated, and there is no limit to the number generated.

The standard is to not allow persistent conference ID’s for security purposes.  In the scenario you have back to back meetings, using the same conference ID would allow the next call to join into the previous call.  This prevents accidental exposure where sensitive data is being discussed.

There can be some use cases where exceptions could be granted (eg. standard dial in crisis line).   A support request to the Messaging Team would need to be made in order to discuss in more detail.

Can this replace my standard conference bridge line?

Maybe.  In a good many situations it can, but it depends on the particular use case.

Known situations where it may not work well:   

  • Conference bridges (eg. via Avaya) can have any user utilize it.  Skype for Business Audio Conferencing can only be scheduled by the organizer that has the license assigned.

There are some needs to have standing call bridges, where data connectivity is never needed.

How much does Skype for Business Audio Conferencing cost?

A Skype for Business Audio Conferencing license cost $1.50 per month.  This is billed to your departmental speed type (smart key).

Any per minute voice charges from cellular carriers may apply.

Can a non-Emory person attend meetings as well?

Yes.  Both Emory and non-Emory users can be invited and attend meetings using Skype for Business Audio Conferencing.
