It’s a complete online phone solution and hence the interface can sometimes be ‘too much’ for fax only users, the entry level plan does not have phone support

Costly priced monthly plans, free trial for just 14 days as against industry standard of 30 days, does not offer fax through email.


RingCentral offers multiple internet fax plans based upon the number of pages. You can either choose to have a common fax number for all your employees or go for a dedicated fax number for each one of them.

Sfax is highly secure, HIPAA compliant cloud based internet fax service that is designed to meet the rigorous requirements of healthcare and other data sensitive industries.
