[Freeswitch-users] How to design my project ?

Hi Miki, I'm not an expert on freeswitch but I'm sure that libfreeswitch 
can be embedded
into c-applications (http://wiki.freeswitch.org/wiki/Embedding_FreeSWITCH).

In addition it possible to write part of an application as an
loadable module (applications in freeswitch are loadable modules). The 
reason for this
is that a loadable module can use the dialplan framework (for example an 
incomping call
can be routed to your application).

It is also a good idea to look into how the scripting languages are used in
FS (http://wiki.freeswitch.org/wiki/Languages_for_Call_Control).

//Accordingly to voipinfo.org 
(http://www.voipinfo.org/wiki/view/FreeSwitch) is FS a library which 
ships with a small
executable that loads the library, launches the core, and performs the 
various tasks
that are defined by the modules (freeswitch applications).

libfreeswitch includes sofia sip endpoint and ASR/TSS (native or through 
MRCP). You need
to modify some configuration files to enable ASR/TSS (sip endpoint sofia 
is default).

Best Regards

Lars Sivertsen
