Phone Log places a pin on a map and creates a new entry in you calendar automatically when a phone call is either made or received or you add an event manually. The pin is set at your location and the calendar entry is at the time of the call. Other call information (like Caller ID and Caller Location) is not yet available. Edit the Calendar entry either in Phone Log or in Calendar to create notes for the call or event. You can attach files like photos and scanned notes to an entry in Calendar. You can select the calendar to be used for the calls. If you use iCloud and sync your calendars the calendar entry will show up within a few seconds and can be edited on your synced device during the call.
