[Freeswitch-dev] Need some info about FreeSWITCH

29 Aug 2008

      We try to write some script extensions for application  LUA & JS & Perl.
There are some questions :

1. Seems, that for use LUA there is no necessity to install lua-5.1.3.tar.gz from
http://www.lua.org/ftp/, also that LUA environment is built in a kernel of FreeSWITCH. Is it correct?

2. In the catalogue scripts it is placed test files:

- 2004.pl
#!/usr/bin/perl
freeswitch::console_log('info', "******Perl*********\n");
my $res = `uname -a`;
freeswitch::console_log('notice', "OS Info: $res\n");
1;

- 2005.lua
freeswitch.consoleLog( "info", "*************LUA************\n" );

- 2006.js
console_log( "*************JavaScript************\n" );
session.answer();
exit();

also we make in addition:
$ luac 2005.lua -o 2005.luac

and add extensions into dialplan:

<extension name="2004">
  <condition field="destination_number" expression="^2004$" >
    <action application="perl" data="2004.pl" />
    <action application="answer" />
    <action application="sleep" data="1000" />
  </condition>
</extension>

<extension name="2005">
  <condition field="destination_number" expression="^2005$" >
    <action application="lua" data="2005.lua" />
    <action application="answer" />
    <action application="sleep" data="1000" />
  </condition>
</extension>

<extension name="20051">
  <condition field="destination_number" expression="^20051$" >
    <action application="lua" data="2005.luac" />
    <action application="answer" />
    <action application="sleep" data="1000" />
  </condition>
</extension>

extension name="2006">
  <condition field="destination_number" expression="^2006$" >
    <action application="jsrun" data="2006.js" />
    <action application="sleep" data="1000" />
  </condition>
</extension>

We fulfil inquiries SIPp to the corresponding extension:
$ ./sipp -sn uac -s 2004 -m 1 opos8:5070
And we takes on FreeSWITCH's console:

- and that is a strange error, при чём, if to change in extension
<action application="jsrun" data="2006.js" />
for:
<action application="javascript" data="2006.js" />
that:

2008-08-29 12:48:16 [NOTICE] switch_channel.c:538 switch_channel_set_name() New Channel sofia/nat/sipp@192.168.2.108:5061 [1cc1f4d6-2986-4733-a2bf-84806ff0b681]

- then error do not arise:

But FreeSWITCH tells:
