Thank you for reaching out.
At this time, there is no feature for this. That said if your EHR has an email inbox to receive their emails through you could add this email to the received faxes notification area, and check the radio button to have the fax attached to the notification email. This would deliver the fax into your EHR in the way you are looking for.
I may be wording this incorrectly, but is there a function that allows the incoming fax to be exported automatically to an EHR inbox beyond a notification of RECEIVED?
Simply curious as it's not at all difficult to click the email function and send the fax itself into the EHR inbox.
