So long as you give proper trademarks and copyright credit on what you use and 
how you present your "product," your own coded modules and your own support of 
the platform is permitted -- is how I read it. This is the basis for using the 
MPL licensing -- to allow people to build their business models over freeswitch 
-- the MPL is business friendly.

Simple rule: If you're using code that you are not permitted to distribute, do 
not use it.

No. If it's via sockets, you may license the external application however you 
wish. That is not the best approach -- you will see a perfomance impact.

 	- Stick to what everyone else is doing.
 	- Remember to credit the systems that you are talking to and the code 
that you are using in one way or another !
 	- Do your absolute best to contribute back.
 	- Many people have put a lot of years worth of hours into providing this 
platform for you to use.


Bear in mind, that you may also rely on the freeswitch base and create your own 
closed source modules that talk directly to the API and compile it in instead of 
using sockets -- all legit within the license.

dialplans/mod_dialplan_directory supports AD/LDAP, iirc -- the directory serving 
machine has its own licensing and is subject to what you've installed to support 
that dialplan info.

- again, that's socket based communication -- there was, a while back, arguments 
re: sockets and licensing on another, different licensed platform.


Someone correct me if I am wrong anywhere, please. x

Thanks,
