This option gives you a phone number, session ID and pin code so your speakers can join their session in case they don’t have access to a computer or to a WiFi network. Dial-in is used to overcome issues with audio and video. Traditional dial-in is possible with VolP technology. For webinars, SIP is used to facilitate the calls. This option is limited to Speakers only. Hosts, moderators or guest speakers who have trouble watching or listening to the live stream, due to their network, firewall or environment can join an event by phone by calling a number and entering an access code.
