Hi, I am interested in a solution that allows asterisk to passthrough T.38 fax support. I do not need to actually handle the fax myself. Here is a brief description of the setup. ATA (T.38 support) => SIP => asterisk => iax => asterisk => SIP => Lucent Softswitch with T.38 support. Notice the ATA device and the Softswitch both support T.38. The asterisk boxes are being used for user authentication and registration. What I am looking for is someway to passthrough the T.38. I know it looks easier than it is, but any suggestions would be greatly appreciated. Gene
