====== Participating in a Web Conference via Telephone ======

In addition to participating in a web conference via the classical method of using audio and/or video, you can also participate via telephone. 

==== Preparation ====

To obtain a telephone number and access pin, you must start a web conference using a PC. You can then find the number and pin displayed in the welcome message via the chat. Note that it is not possible (until further notice) to send a number and pin in advance. \\
