What is a Fax Demodulator?
Last Update: August 9th, 2021
The difference between a fax demodulator from a regular fax machine is that the fax demodulator can only be used to observe the fax signal – it does not participate in the fax handshake or two-way communication that occurs between fax machines.
Use of Fax Demodulators for Legal Purposes
A fax demodulator (either a software or hardware version) is commonly used to intercept fax signals over PSTN communication lines. An example of this software is found from the company Vocal Technologies.
