Hi @all I have a question about a project I want to realize with FreeSwitch. I want to do a complex IVR System which takes a call, do many things in a MSSQL DB, send some Informations to one or many Middleware Servers via TCP/IP, call one or more mobile phones, the first is able to take the call, it can be that he must be able to hear a prompt before he is actually connected to the first caller, then the conversation must be recorded automatically and during the conversation it must be possible for the called party to redirect the call by dtmf. I know that this is all possible, but I want to know which way is the best to do all this?

Hi Guido,

My preferred way is to talk to FS through its event socket
interface. This allows you fully to control FS, whilst giving
you the power to write the code in whatever language and on
whatever platform you choose.

The documentation starts here:

To add to David's comments:

Have a look at ESL, which is the event socket library that the fs devs created. It's an abstraction layer that makes it easier to use the event socket with the programming language of your choice. In fact, the program "fs_cli.c" is a great example of a program that uses the ESL to talk to a FreeSWITCH server. (fs_cli = FreeSWITCH Command Line Interface program, kinda like "asterisk -r" if that means anything to you...)

Your project is most definitely possible with FreeSWITCH. A number of people in the FS community have done bits and pieces of what you've described. Your big challenge is that you're going to need a person or a team who understands multiple technology concepts and how to integrate them: telephony & signaling, socket communications, database management, scripting and programming, etc.

This is a bold project and I would love to see you use FS to be the telephony engine. Let us know what you decide. Also, if you need professional FS assistance you can request it at consulting@freeswitch.org (consulting@freeswitch.org).
