Freeswitch is related to the Perl language

This article is from csdn lidp http://blog.csdn.net/perfectpdl. please refer to this Article. Thank you.

I have created a freeswitch kernel research and exchange group, 45211986. Welcome to join. In addition, we provide the SIP-based communication server and client solution,

Develop the SIP/IMS video client and support access to sipSwitch, IMS core network, supported
Voice, video, and instant messaging functions. The video formats support h263, h264, and MPEG4 soft encoding solutions. The hardware coding/decoding interface is provided for interconnection and servers. If you are interested, contact me.

Freeswitch uses the Perl language mainly in two places: one is to connect the freeswitch event socket module using the Perl language, and the other is to write dialplan using the Perl language through the socket connection, which is similar to the AGI of Asterisk, to write dialplan, the module mod_perl is required. The first usage does not require mod_perl support.

A) install mod_perl:

Gdbm-devel and db4-devel need to be installed on centos

Yuminstall gdbm-devel db4-devel

Modify the modules. conf file and remove the comments of mod_perl.

Installation of Makemod_perl-install

Modify CONF/modules. conf. XML to remove the mod_perl annotation.

B) Use Perl to write dialplan

In dialplan, you can use the system app or Perl app to directly call the Perl script.

Used in XML dialplan

 
<Action application = "Perl" Data = "/path/to/Your/script. pl"/>
 

Or

<Actionapplication = "system" Data = "/path/to/APP. pl"/>

Call the Perl script.
