A+ Conferencing is now able to offer “bridge quality” audio conferencing to Skype for Business within the Office 365 license. This initiative allows users within a Skype for Business, formerly Lync environment, which is a component of Office 365, to invite external participants to join their conference calls by simply dialing a phone number and passcode, just like any other conferencing service on a pay as you use basis.
Now the entire outside world can be invited to attend Skype for Business conference calls. This ability to integrate with Office 365 is not just like any other service. Only a select few providers have been authorized by Microsoft to integrate their service with the Skype for Business platform, says A+.
