I'm setting up a Freeswitch 1.10.7 server on Debian Buster, and when sending faxes using "originate" the fax goes through, but the call is never hung up.
for some reason it's just not proceeding to the hangup stage.
I'm using the default config files and dialplans, with the only change the SIP profile and RTP port config.
Hangs up only because I shutdown freeswitch manually after waiting another 6 mins to see if fax will hang up automatically.
Please let me know if you need any more details.
