10 Using IP Fax (SIP)
IP Fax (SIP) Overview
IP Fax (SIP) is a fax feature that sends and receives document data via the IP network of a
corporation (the intranet). The IP Fax (SIP) complies with ITU-T Resolution T.38.
Because the IP Fax (SIP) uses the existing IP network for communications, you can reduce
the telecommunications costs compared to a conventional G3 fax machine that uses the
public telephone line.
