Hi all. Hope that some on can help...... I have a problem with t38 from at audiocodes gateway to FS as fax receiver.... FS changes the UDP port form 15000 to 15002. I have tried setting <param name="disable-rtp-auto-adjust" value="true"/> in <gateway> and in the profile settings section without any luck I have also tried setting the <action application="set" data="disable_rtp_auto_adjust=true"/> in the dial plan but still it's not working. My audiocodes GW expects to get an answer on the same port that it's sending on Please HELP :o) Regards Martin
