When I'm join a Webex-Meeting and I select "Call in" a link is provided which starts the Cisco Jabber an the phone-number, meeting-id, ... is dialed. This is a fancy feature as VoIP is not always possible due to network issues.
When not in the office i sometimes have to call in via my mobile phone. This means Dialing the phone-number an all the credentials manual (mostly 2-3 times due to errors).
Why not additionally providing a QR-Code, containing all the credentials needed, like phone-number, meeting id, ... which can be scanned by my iPhone for dial in?
