You can join a Zoom meeting via teleconferencing/audio conferencing (using a traditional phone). This is useful when:
you do not have a microphone or speaker on your PC/Mac,
you do not have a smartphone (iOS or Android) while on the road, or
you cannot connect to a network for video and VoIP (computer audio)
Zoom has toll numbers available for many countries that are included with all plans. For audio plan subscribers, Zoom also has toll-free and additional toll numbers available. The dial-in numbers available are dependent on the host’s audio subscription and settings.
