[Asterisk-Users] Asterisk Interface to propriotary system and GPL

[Chris Albertson]

If everything on the Aterisk side of the socket is GPL'd
I think you are OK.

Look at the example of a Linux system running Netscape
browing the web when there is a Microsoft HTTP server.
Then we have a GPL's system conected to a closed
comercial system over a socket (port 80).

The grey area is when you link GPL's code to non GPL
I think the case of a socket interface is pretty clear.
