[Freeswitch-users] mod_fax feedback

[Gonzalo Servat]

Good old fashioned "bump" mailing-list style :-) I'm mainly concerned with
2) .. any ideas as to why the channel never gets hanged up? I had a look at
the mod_fax.c code and it doesn't hang up the channel once a fax
transmission ends so it should return to the dialplan .. right? The next
application to execute should be "hangup" but it never does.

Thanks
