What is fax over IP?
Fax over IP (FoIP) is a term used to describe sending faxes using a voice-over IP (VoIP) network. FoIP uses a protocol like T.38 or G.711 to encode the file into a format suitable for sending over SIP trunks.
Why is fax still used?
Fax is still a popular choice in applications where there are legal and regulatory considerations, such as transferring documents that require hard-copy signatures, and protected health information (PHI). It’s also popular as a backup communications method in case of internet connectivity issues.
How can I send fax via API?
You can send and manage fax programmatically in just a few lines of code using the Telnyx Programmable Fax API. Learn how to get started by checking our developer docs.
