[Freeswitch-users] Cannot collect digits from lua script

[Nicoleta Lazar]

Hello all,

I have a mod_erlang_event based application and I need to run a lua script within for playing prompt and colecting digits (I use freeswith api and luarun from erlang code for running lua script)
The script should collect digits, similar to: 
freeswitch.consoleLog("notice" , "Before GetDigits\n"); digits = session:getDigits(1, "#", 10000); freeswitch.consoleLog("notice" , "AFTER GetDigits\n"); session:execute('flush_dtmf');  freeswitch.consoleLog("notice" , "flush DTMF 2\n"); freeswitch.consoleLog("notice" , "After Get Digits" .. "\n"); freeswitch.consoleLog("notice" , "digits = " .. digits .. "\n");


However, the digits are not collected (sometimes this scenario works OK but I cannot identify a pattern), as can be seen from the logs below:

I also looked in the freeswitch code:
https://freeswitch.org/ fisheye/browse/freeswitch/src/ mod/event_handlers/mod_erlang_ event/mod_erlang_event.c?hb= true#to159

and it seems that the DTMF event is properly cloned and added to current session queue.
Please advise
