Find Call History by Phone Number
Resolve a phone number to a contact ID, then retrieve that contact’s call history.
Call history requires a contact ID. Do not put a phone number directly in
If no contact matches, check the organization and number format before creating or changing records. For date, status, or other call filters, use List calls with its documented query parameters.
