Dial-out Conferencing for non-Enterprise Voice users

  • 아티클

We recently ran into a problem with one of my customers around Lync Dialin Conferencing. The problem was around using the “Call me at:” feature while joining the audio portion of Lync online meetings.

Unfortunately we found out that in order for this dial back to succeed either the organizer or the participant must be enabled for Enterprise Voice (EV) in Lync. If neither users are enabled for EV then you will get an error at the bottom of the client saying it couldn’t connect.

There is one way to get around the requirement of being EV enabled but it’s not supported. You can add a static route to the mediation server which would allow all outbound calls. The drawback is now you have just given any Lync client the ability to call any phone number. Probably not the best idea. So there really isn’t any way to accomplish this that is supported besides EV enabling your users…until….Lync 2013!

With the release of Lync 2013 gives us a new feature called “Dail-out Conferencing for non-Enteprise Voice users”. This can be configured by setting the Conferencing policy to allow this feature (Set-CSConferencingPolicy –AllowNonEnterpriseVoiceUsersToDialOut:$true). After enabling this you can then assign a voice policy to this user and they will be able to take advantage of this feature. Another Great reason to upgrade to Lync 2013 :)

    @Pat - I don't think there is an option to force this unfortunately.

    I've looked around, and can't find, a way to force the "Use Lync" option so that users can't select from the drop down list. Any way that you know of to do this?

    @Pat @Doug - there are the two keys Doug mentions in his blog that can be used to set the default value. Unfortunately the user can still go into the client options and change this at anytime which might not be an issue. Also note for the 2013 client the REG keys are located HKCUSoftwareMicrosoftOffice15.0Lync. Thanks Doug for pointing this out.

    Allow anonymous participants to dial out This setting allows anonymous users who are already joined to the meeting to dial out to a phone number to join the audio portion of the conference. This setting is optional for dial-in conferencing. This setting is not selected by default in the default global conferencing policy.
