The file app_faxmail_onramp_callflow.fm is in the zip file of onramp tcl application, what's the file for? it's not a text file. I just test onramp t.37 fax in a 3600 and 3845 router, but both fail, I just can hear busy tone what I fax to the fax number. I don't know if I also need to copy this file to flash.
Thanks!
Best Regards,
