There is some C implementations of ESL stuff on my contrib dir as well if anyone is interested... Also, FSGui is all ESL with Qt and can also be found on my contrib dir. Regards, João Mesquita On Fri, Feb 18, 2011 at 10:27 PM, Michael Collins <msc@freeswitch.org>wrote:

I'm learning to use ESL in C++ to do a call control and I want to share my code with the community.
I had a little difficult at startup so I hope that this code can help someone.
The code is: http://pastebin.freeswitch.org/15418
Using "esl_oop" module, I have implemented a basic ESL Channel class (that can be extended) so the "main" event handling loop can be very simple, for example for an unuseful esl bridge application, can be:
ESLchannel legA(&connection, inbound_uuid);
ESLchannel legB(&connection); legB.Originate(dialstring)
while (1) { ESLevent * event = connection.recvEventTimed(1000);
if (event) { const char * ename = event->getHeader("Event-Name"); const char * event_uuid = event->getHeader("unique-id");
// It's an event for LegB ? //------------------------- if (legB.Uuid() == event_uuid) { if (!strcmp(ename, "CHANNEL_PROGRESS_MEDIA")) { legA.PreAnswer(); legA.BridgeTo(legB); } else if (!strcmp(ename, "CHANNEL_ANSWER")) { legA.Answer(); legA.BridgeTo(legB); } else if (!strcmp(ename,"CHANNEL_HANGUP")) { const char * cause = event->getHeader("Hangup-Cause");
legA.Hangup(cause); } } // It's an event for LegA ? //------------------------- else if (legA.Uuid() == event_uuid) { if (!strcmp(ename,"CHANNEL_HANGUP")) { const char * cause = event->getHeader("Hangup-Cause");
legB.Hangup(cause); } }
delete event; } }
