Currently if you need to join a meeting on the go, the only way to do that is through the teams app using data on your phone. Webex has an option to use a phone line connection only. I don't even care if Teams can call me at this point (like webex can) - I just want the option to call in myself using my phone number and not my data connection when I'm driving between locations and don't have WiFi. Also, I don't want the option to look at the screen while driving, so an audio-only connection would be perfect. This is NEEDED!
