We just started using Ring Central efax service. It cost $35 a year and you have unlimited cloud fax service. We usually have around 500+ pages monthly easily. the efax comes in as PDF and our staff can save the PDF fax directly into AC. We also have our own dedicated fax line out that we use our brother MFC to do this. I think updox is good but costly on the fax side. Plus I hate having to be "charge extra." if we go over our fax page limit. HTH
