Hi, T.38 FAX support via nf_nat_sip,nf_conntraack_sip does currently not seem to work, because the REINVITE for the codec change is not handled correctly at the moment (Figure: Fax Pass-Through and Call Flow diagram i.e. at http://docwiki.cisco.com/wiki/Cisco_IOS_Voice_Troubleshooting_and_Monitoring _--_Fax_Call_Flow ) Do you have an idea how to patch this problem? -Florian -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
