Hi BERGANZ François,

T.38 is not transfered in SIP packets. The sip only contains the SDP offer for 
T.38. The actual data is transfered in UDPTL packets, which contains in a 
binary format (ASN.1 i think) the fax data. Use wireshark to take a look into 
the packets, its a bit hard to decipher this manually. :)

Cheers,

Henning
