T.38 Protocol
What is it and how it works
messaging services since 1992
• Faxes were initially designed to be
transmitted over a TDM or POTS (plain old
telephone line) network
• Trying to send a fax over an IP network can
cause packet loss, delay and jitter. Not an
ideal situation
• Enter the T.38 protocol
• T.38 is a protocol developed in 1998 to
allow the transmission of Faxes over an IP
(Internet Protocol) network
T.38
What is it?
messaging services since 1992
• For most people T.38 will not impact a fax in
any way other than it lets you send a fax
over the IP network no matter what the
receiving device is:
• a fax machine
• fax board
• IP fax service

Illustration of T.38
messaging services since 1992
• The T.38 protocol is a critical component for
utilizing IP gateways instead of traditional
phone systems. Trying to use an IP network
without T.38 will dramatically increase call
disconnects
• Having high availability on your fax gateway
is still critical for your fax arriving at your
destination correctly rendered and with no
transmission errors
T.38
What is it?
messaging services since 1992
• T.38 is an important protocol, however
Reliability and throughput are the most
critical components for delivering a fax
• Choose a service provider who is more
concerned with deliverability statistics than
Least Cost Routing
• When a service provider implements Best
Deliverability Routing (BDR) instead of LCR,
you have a much more efficient solution and
a higher success rate for your faxes
