How do i make Gong automatic for all my calls ?

We use Salesloft, so every outbound call made through the Salesloft dialer gets recorded in Salesforce as a Task/Event. Gong finds and transcribes the call from there. My SDRs wouldn't make a call that doesn't get recorded to the correct Lead/Contact in SFDC. Then for external meetings on a calendar, Gong is able to add itself as long as the Chime/GoToMeeting/Zoom link to the meeting is in the Location of the invite.

It depends if your IT department has it integrated with your sales force or whatever software you are using.

You can control this in configuration settings. You should not have to log into Gong for it to record.
