The EFAX cloud-based solution simplifies operations and management of fax services, enhances reporting, and improves availability within a secure and compliant environment.

  • Security: complies with HIPAA, FRPA, PCI regulations.

What is the EFAX file size limit? 

  • The EFAX attachment size limit is 20 MB.  

Is there a limit to how many fax pages I can send or receive?
