When you receive an email invitation to a Webex meeting, it'll look something like this.
For your convenience, choose however you'd like to join the meeting from your computer, mobile device, traditional phone, or video system. Choose the option that's best for you.
Join from Your Computer or Mobile Device
Select Join to join the meeting from your computer or mobile device, tap or click the green Join button. After you join, you can see everyone in the meeting, shared content or share our own video and content.
Join from Your Phone
Call one of the numbers under Join by phone. This is a good option if you aren't connected to a network for video. After you join, you can hear everyone talking in the meeting but not their video or content that they're sharing.
Join from a Video System
If you have a Cisco Webex room or desk device, or another video system, you can join the meeting from a video system. From your device, enter the video address to dial, under Join from a video system or application.
