IVR Application in Lua for Freeswitch

5:57 pm in FreeSWITCH, Lua by admin

1. Create a New file name 01_Custom.xml and add the following new extension:

<extension name=”Read Back Entered Digits”>
<condition field=”destination_number” expression=”^(9910)$”>
<action application=”lua” data=”test1.lua”/>
</condition>
</extension>

2. Save the file. Launch fs_cli and issue reload_xml, or press F6.

Our Dialplan is now ready to call the Lua script named test1.lua. Create this new script as follows:

1. Using your text editor, create test1.lua in the freeswitch/scripts/ directory and add the following lines:

– test1.lua
– Answer call, play a prompt, hangup

– Set the path separator
pathsep = ‘/’ — Windows users do this instead:
– pathsep = ‘\’

–Answer the call
session:answer()

–Create a string with path and filename of a sound file
prompt = “ivr” .. pathsep .. “ivr-welcome_to_freeswitch.wav”

– Print a log message
freeswitch.consoleLog(“INFO”,”Prompt file is ‘” .. prompt .. “‘\
n”)

–Play the prompt
session:streamFile(prompt)

– Hangup
session:hangup()

2. Save the file.

Now dialer 9910 and you will get IVR.
