Something is worrying me a bit about this :

if T38FaxUdpEC value in udptl.conf is device-dependent, then how can you set
different values when using different devices :
device A needs t38UDPFEC
device B needs t38UDPRedundancy
then which value in udptl.conf ?

(when asking this, I'm implying Asterisk is a B2BUA and receives/transmit
each T.38 call leg.
I'm understanding this correctly ?)
