Fax is a great way to connect with other businesses, send sensitive documents, promotions or create marketing campaigns, with or without an actual physical fax machine. You can setup a fax system quickly and get started with any of your campaigns.
How does T38 fax work?
Fax machines on the PSTN communicate using the T30 protocol. T38 encapsulates the T30 transmission in real-time and uses data redundancy methods to ensure the complete delivery of a fax. By sending the same packets up to 5 times, most issues with jitter and packet loss on the last mile do not affect the fax completion rate.
