[Freeswitch-users] Getting started on dev

Well, one thing I would like to offer up a COM/CHANNEL, like remoting, but a little more.  One of the largest issue I see with Asterisk, was the requirement to run as a sole system, and not really distributed. If in fact this is to be a switch, then one should assume that say SS7 signaling should be on two separate "nodes", not part of the physical system the s/s is on, as well as the s/s should be redundant in processing, and possible a routing system should be distributed.  Take your .NET registration to the various interfaces, then "Add-in" a serializable communication link between nodes, so actual applications, or services could exist on other boxes/nodes, (eg: TDM Gateway), or IVR, or signaling.....

It would allow developers to develop applications without actually having to have a switch, but simply register up to the host/softswitch and all eventing, procedural calls would be done over line protocol..

This is much in the way how real switches work today, cisco, sonus, etc...

Thoughts?

Shawn,

Definitely, I hope to create a community within the community  
surrounding the .NET components. I was always holding out doing this  
project with asterisk because of the weekly instability and changes  
they go through, then Freeswitch came about, it was perfect and I ran  
with it.

Many people are excited about this module and I can understand why,  
so over this weekend I'll try my best to put aside some time and  
write up some tutorials about what's been done, and what needs to be  
done. I will definitely be looking for help as this will be a pretty  
extensive project, requiring it's own documentation, tutorials and  
the like. The good thing though is that it's dead simple to create  
modules, below is a working example of a module (a port of the record  
function in mod_playback using some older ivr functions). Bear in  
mind that this is bytecode compatible, I currently build the stuff  
I'm working on using Visual Studio (also compiles with gmcs) and  
execute in Mono on Linux.

using System;
using System.Text;
using Freeswitch;
using Freeswitch.Modules;
using Freeswitch.Types;

namespace Record
{
     public class Record : Module
     {
         public Record()
         {
             AddApplicationInterface(new RecordApplication());

             Register();
         }
     }

     public class RecordApplication : Application
     {
         public RecordApplication()
         {
             Name = "dotnetrecord";
             Syntax = "dotnetrecord /file/name";
             ShortDescription = "short description";
             LongDescription = "long description, long description,  
long description";
             ApplicationFunction = new ApplicationFunction 
(RecordApplicationFunction);
         }

         public Status OnDtmf(CoreSession session, string input,  
InputType inputType, string buffer, int bufferLength)
         {
             if (inputType == InputType.INPUT_TYPE_DTMF)
             {
                 string dtmf = input;

                 Console.WriteLine("Digit {0}", dtmf);

                 if (dtmf.Contains("*"))
                 {
                     return Status.False;
                 }
             }

             return Status.Success;
         }

         public void RecordApplicationFunction(CoreSession  
coreSession, string data)
         {
             if (Ivr.RecordFile(coreSession, null, data, new  
InputCallbackFunction(OnDtmf)) != Status.Success)
             {
                 coreSession.Channel.PerformHangup();
             }
         }
     }
}
