With TrueConf Server, you can make calls to video conferencing endpoints via SIP/H.323 and join video meetings hosted on third-party video conferencing platforms. Currently we support integrations with popular cloud-based services such as Zoom, Cisco Webex, Lifesize Cloud, and GoToMeeting. This article describes how to join video conferences hosted on these cloud-based services.

Please note that you can join meetings hosted on a third-party video conferencing platform via SIP/H.323 only in case the corresponding feature is enabled on this cloud-based service. To learn more please contact your meeting organizer.
