If you want your developers and stuff to be happy please AVOID webex !
Webex is bad service
It has bad International connection. It doesn’t run on linux or unix and can’t be run in a browser. The IOS application is bad and doesn’t integrate with the links. The integration with the website and the calendars is bad. The website is slow and buggy and you can’t see the meeting on which you are invited. It is the worst of the software out there.
Zoom – It is like the webex. They look and feel the same one idea better, because it has client which can run in linux
