[Freeswitch-users] Freeswitch in an existing phone network

[Tim St. Pierre]

Hi Oliver,

FreeSwitch will do whatever you tell it to do and no more.

Here's a few suggestions though -

Empty out the default dialplan directory.  Don't throw those away, as you may want to reference them
as examples, but move them somewhere else.

Edit modules.conf.xml and comment or remove any modules that you don't need.  This will also save
memory and other resources.

You can also disable all the SIP profiles except one.  Pick one that makes sense (either Internal or
External, it doesn't really matter that much), and edit it so that it makes sense with respect to
your network.  What is your topology?  Will you just be setting freeswitch up with a static IP
address and having calls sent to it by the main PBX?  If that's the case, you can disable a lot of
the STUN and uPNP functionality.  Tell this profile to bind to the IP and port that the PBX will
send the calls to.

Then all you have to do, is create a very simple dialplan that will answer an incoming call and
perform whatever task you want.  You would essentially be starting with a blank sheet, adding just
the functions that you want.

Hope that makes sense.
