Hi, Nice work on mod_fax! I just tried sending myself a couple of faxes and they were received successfully. I even tried using tone_detect which correctly detected the fax machine and fired off rxfax. I wanted to report back on a couple of issues: 1) Even though the spool dir is set to /tmp/, I called up rxfax with data="rxfax.tiff" and it saved it in /. Shouldn't it save it in the spool dir? 2) After receiving the fax, the channel is never hanged up. The tone_detect app even detects the busy tone (which calls the hangup application when it detects it) but it just sits there for a long time until I manually uuid_kill it.
