Currently we can setup Audio only telephone conference calls, or Video Webmeetings. Please allow an option so participants can call in for the audio portion of a webmeeting. This will allow participants without speakers and/or a microphone to participate, along with those who have no computer access or a poor internet connection. The invite email should include instructions to use computer speakers/microphone or to use a telephone and dial in number to join the audio portion of the conference. The dial in number and conference ID should also be displayed in the webmeeting. I understand the licensing for concurrent webmeeting participants and simultaneous calls could be an issue, which is why this should be an option at the client level and would be selected when scheduling the conference.
