The Ottspott Hangouts Chat bot can be used in any room where you have installed the bot.
To place an outbound call in a room please type :
@Ottspott .call number (in international format)
@Ottspott .call 33685162667
If you are in direct message with the Ottspott bot, please type the same command without @Ottspott behind the command ".call".
Click on "Launch your call in Ottspott".
The call page will open in a Chrome browser tab and you can now speak. If you've never used Chrome to handle calls, you will have to allow the microphone first.
