ha ok got it.
so in case of txfax app should I use early_media ?
in the case of the call is already answered can
I run the app from uuid_broadcast or uuid_transfer if
the app is in an extension ?
I tried the last but it makes a fax timeout
What exactly did you do that resulted in a fax timeout? Please pastebin console log w/ the extension in question and whatever API commands you sent.
