Just checked and all SDP lines are ended by "0x0d,0x0a". So I went to 
the code and founded in textops.c that filter_body is looking for the 
string "--Boundary" while Cisco GW uses "--uniqueBondary" as boundary 
identifier (see the printed $rb on the logs below).

So I twiked the code to also look for the string "--uniqueBondary", 
recompile and this ERROR message is gone... Now I got new ones from 
NATHelper (see the last lines below) ... Will look the code, but sure if 
I could do a thing...
