In sip.conf add to [general] context and to every peer context that you
want to register in Asterisk to use T.38 the following lines:
t38pt_udptl=yes
t38pt_rtp=no
t38pt_tcp=no

In udptl.conf file I have the following configurations:
[general]
udptlstart=4000
udptlend=4999
T38FaxUdpEC = t38UDPRedundancy
T38FaxMaxDatagram = 400
udptlfecentries = 3
udptlfecspan = 3


Good luck,

Ricardo.
