Hello, i try to use mail2fax with asterisk. all i have found is old stuff like - https://sourceforge.net/projects/asterfax/files/production/NoojeeFax or - https://github.com/siddolo/sidfax so I try sidfax (aka email2fax). Now asterisk show in sip debug mode the following error. [17-06-2020 18:06:11] WARNING[6269]: pbx.c:7487 pbx_outgoing_exec: No such application 'txfax' [17-06-2020 18:06:11] NOTICE[6268]: pbx_spool.c:426 attempt_thread: Call completed to SIP/.../... txfax seem to be a port of spandsp. it is also old. Is there a newer way to send fax via asterisk.
