Enabling 3rd Party Audio

When 3rd Party Audio is enabled, your meeting participants can join with the 3rd party audio conference phone number that you provide, instead of the VoIP or PSTN number you provide through Zoom. It is important to note that third party audio conferencing has the following limitations:

  • After the option is enabled or disabled, users must sign out and sign in to their desktop or mobile application in order to view the scheduling option.
  • Once the 3rd party audio option has been selected, it will only be used for that particular meeting.
  • Audio is not recorded while the meeting is being recorded.
  • It will not be possible for active speakers to be detected during this time. Therefore, please pin the speaker, highlight the speaker, or switch to the gallery view in order to detect active speakers.
