Hello, list. My ITSP supports T.38 for faxing pretty well and i _can_ send fax using ATA D-Link 5008s with t38_passthru <action application="export" data="t38_passthru=true"/> Now i want to use FreeSWITCH-box as the fax gateway to send all faxes to asterisk box using transcoding from T.38 to just audio. My setup for outbound call: FAX --> ATA --> T.38 --> FS --> T.38 --> ITSP --> customer PSTN FAX This setup, using t38_passthru, works pretty reliable. Now i wanna: FAX --> ATA (fax disabled for purpose to not RE-INVITE) --> ALAW --> FS --> T.38 --> ITSP --> customer PSTN FAX or FAX --> ATA (fax disabled for purpose to not RE-INVITE) --> ALAW --> Asterisk --> ALAW --> FS --> T.38 --> ITSP --> customer PSTN FAX asterisk as a registrar for all endpoints @ office and FS (virtual machine) act as simple *sic* fax gateway. So, I swear, i tried all the configuratings from wiki ( http://i1110.photobucket.com/albums/h447/jugatsu85/280312-1.jpg) but it doesn't work at all. According to your requestd i'll post all pcap/flat dumps (actually, when i resolve a issue with my ITSP sending 403 Forbidden ^_^)
