How to Log a Call in Salesforce (Lightning Experience)

To log a call in Salesforce, open the contact, lead, account or opportunity, click Log a Call in the Activity panel, enter a subject and comments, and click Save. Salesforce stores the call as a completed Task with Task Subtype = Call and shows it in the record’s activity timeline.

I logged a real call on a contact in a Salesforce Developer Edition org (Lightning Experience) and then queried the saved record, so every step and field below is what Salesforce actually did. You will also see how Log a Call differs from a task, how to report on logged calls, and what automatic call logging needs.
