Not SIP, but over TCP/IP, I have been happy with iFax from www.ifaxapp.com <http://www.ifaxapp.com/> which takes a  document and a phone number and sends the document to that number. Charging is against credits which are available at varying prices. 

The iFax application is available for macOS, Windows, iOS, and Android. I use it on iOS and macOS. See the website for more details on inbound fax, document scanning, HIPAA, and other features.
