According to Wikipedia, "T.38 fax relay standard was devised in 1998 as a way to permit faxes to be transported across IP networks between existing Group 3 (G3) fax terminals. T.4 and related fax standards were published by the ITU in 1980, before the rise of the internet.

TelcoBridges and T.38
TelcoBridges provides native support for the T.38 fax relay standard.
