Hi all ... I'm trying to find why an T.38 call doesn't work throught a
SPCE mr3.4.1

I have this SDP coming from the kamailio­proxy to the kamailio-lb

o=root 958158857 958158858 IN IP4 XX.XX.XX.XX 
s=Asterisk PBX 11.12.0
c=IN IP4 XX.XX.XX.XX
t=0 0
m=image 11830 udptl t38
c=IN IP4 XX.XX.XX.XX
a=sendrecv

a=T38FaxRateManagement:transferredTCF
a=T38FaxMaxDatagram:849
a=T38FaxUdpEC:t38UDPFEC
a=rtcp:11831
a=direction:both

And this one from the kamailio-lb to the UAC that initializated the
call

Does anyone know why kamailio-lb truncate the SDP package ? ...,
because it's obviously truncated.
