[Freeswitch-users] Transfer out of lua script on fax detection - novice user

I am having trouble with fax detection while executing a lua script: I am setting the fax detection in the dialplan: <action application="tone_detect" data="fax 1100 r +3000 transfer 'fax XML public' 1"/> and continue by executing a script: <action application="lua" data="laczenAMS.lua"/> when a fax is detected (this works fine) during the execution of the script, the script exits and the call is hangup. How can I avoid the hangup and continue with the fax receiving ? Kind regards, Jehudi
