No. handSIP T.38 Fax SIP Trunking service does not store any sent or received faxes. handSIP provides a T.38 SIP trunking service in the same way a phone company provides a phone line to your office or home. handSIP simply carries the call and does not retain any of the faxed data. In order to fax via handSIP, a fax machine or fax server must be used to handle the fax calls. Going back to our phone company analogy, this is the same manner that a phone would be used to make and receive phone calls using your phone line.
