Ricardo Carvalho <rcarvalho at iric.up.pt> wrote: 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.
