A “Zoom call-in number” is a telephone number that allows participants to join a video conference using a traditional phone line rather than an internet connection. For instance, in a meeting invite, you might see a Zoom call-in number listed as “+1 (646) 558-8656”.
Call-in numbers make it possible for individuals without reliable internet access or those in remote areas to participate in virtual meetings. They also serve as an alternative for users experiencing technical difficulties with their internet connection. The introduction of call-in numbers in video conferencing platforms, such as Zoom, expanded the accessibility and inclusivity of remote communication.
