Hi all,
 
I have run into an issue on something so basic that I must be as simple as enabling a feature somewhere.
 
I have been trying to get lua to play a message from a WAV file. I have tried session:execute("playback", main_msg) and session:streamFile(ivr_invalid_msg) but neither of them play any music to the caller. I tried both to answer and preAnswer the call first but it made no difference. However if I put the same file into the XML dialplan and play it with the commands below I hear the music fine.
<action application="set" data="playback_terminators=#"/>
<action application="playback" data="${401_sound_file_path}"/>
 
The issue only seems to be from lua when playing any type of wav file and those files are definitelly there as can be read by the XML
 
The error message is below for the execute(playback) command, but nothing can be seen for the
2010-12-01 11:56:01.534727 [DEBUG] switch_core_session.c:1827 Application playback Requires media! pre_answering channel sofia/external/2031701665@194.0.147.16:5060 EXECUTE sofia/external/2031701665@194.0.147.16:5060 playback(/usr/local/freeswitch/sounds/svc_sound_files/default_autoattendant.wav)

But there is no mention of the streamFile command. I have had similar issue with the PlayAndGetDigits command.
Is there something that I need to enable in lua so that is can playback messages to the caller.
 
Many thanks to anyone who can help.
Marc
 
 
below is the XML dialplan and lua script as well as the log at the very end.

 
XML DIALPLAN:
<include>
<extension name="IVR_FROM_MYSQL">
<condition field="caller_id_number" expression="Anonymous" break="never">
<action application="set" data="effective_caller_id_number=0000000000"/>
</condition>
<condition field="destination_number" expression="^(404)">
<action inline="true" application="lua" data="ivr_mysql.lua ${destination_number:3}"/>
<action application="set" data="effective_caller_id_name=${404_tag}"/>
<action application="bridge" data="${404_dial}"/>
</condition>
</extension>
</include>
 
The LUA script ivr_mysql.lua is callsed and this is it.
-- IVR : PLAY IVR WAV FILES
-- Global Variables:
local dialstr_prefix = "sofia/gateway/CS2k/"
local dialstr_main = ""
local breakoutcode = "184"
local sound_file_folder = "/usr/local/freeswitch/sounds/svc_sound_files/"
local ddi = argv[1]
-- answer the call
session:preAnswer();
freeswitch.consoleLog("info", "All Answered\n");

ivr_invalid_msg = sound_file_folder .. "invalid_msg.wav"
main_msg = sound_file_folder .. "default_autoattendant.wav"
-- Play with Execute
session:execute("playback", main_msg)
-- Play with StreamFile
session:streamFile(ivr_invalid_msg);
dialstr_main  = dialstr_main .. dialstr_prefix .. breakoutcode .. "02031701665"
session:setVariable("404_dial",dialstr_main)
session:setVariable("404_tag","IVR")
