+= Enabling External Sound Device Configurations =
+
+External sound device configuration enables application to provide its own sound device implementation rather than the implementation provided by PJMEDIA. This option was added in PJSIP version 0.9.5.
+
+== GNU Build System ==
+
+Follow these steps to enable external sound device with GNU build system.
+ 1. Enable external sound device in {{{./configure}}} command:
+  {{{
+./configure --enable-ext-sound
+  }}}
+ 1. Edit {{{user.mak}}} in root PJSIP directory to add your sound device implementation in the link process. For example, if your sound device implementation is in {{{ext_snd.c}}} in your home directory, the content of {{{user.mak}}} file will look something like this:
+  {{{
+# This is the rule to compile your sound implementation
+~/ext_snd.o: ~/ext_snd.c
+        $(APP_CC) $(APP_CFLAGS) -c $< -o $@
+
+# Specify this so that your file will be compiled when 'make all' is invoked
+all:    ~/ext_snd.o
+
+# Add your implementation to LDFLAGS
+export LDFLAGS += ~/ext_snd.o
+
+  }}}
+  Note that all directory reference must use full path rather than relative path, since the {{{make}}} command will be invoked in {{{build}}} directory of the libraries rather than in root PJSIP directory.
+ 1. Build everything:
+  {{{
+make
+  }}}
+
+
+== Visual Studio and Others ==
+
+Follow these steps to enable external sound device with Visual Studio build system.
+
+ 1. Declare this in your {{{config_site.h}}}:
+  {{{
+#define PJMEDIA_SOUND_IMPLEMENTATION    PJMEDIA_SOUND_EXTERNAL
+  }}}
+ 1. Add your sound device implementation source file in the '''application''' project (e.g. in application's Visual Studio project, or in application's MMP file for Symbian).
