[Freeswitch-users] Problems with FAX transmission

I'm trying to send a fax via our Freeswitch switch without success. It
seems that the "invite sdp (t38)" message isn't forwarded from the
gateway of the fax receiver to the gateway of the fax sender. See the
attached tif file with the Wireshark trace.
If I try the fax transmission with the same setup with a commercial
softswitch (same fax equipment, same sending and receiving gateways),
the fax transmission is successful.
We are using the following settings in the sip_profile
<param name="inbound-codec-negotiation" value="greedy"/>
<param name="inbound-late-negotiation" value="false"/>
Does anybody know what's going wrong?
Thank you in advance
