[Freeswitch-users] Getting Started Answering Calls

[Brian Tanner]

Hi there. I might end up being active in this list, so I'll introduce  
myself.  My name is Brian, I'm a complete newbie to telephony systems  
in general.  I'm sorry, I know that can be frustrating, I don't really  
know the jargon and I don't really understand how things work.  The  
good news is that I am good at figuring things out and I like to fiddle.

Let me see if I have my jargon right:

I have a DID mapped to AIX with a service provider (DID WorldWide).  I  
have a cable modem at home, and my laptop (where FreeSwitch is) is the  
DMZ.

I haven't touched the FreeSwitch config.

When I call my local DID, FreeSwitch answers:

So, the crash sucks, and doesn't happen every single time.  I'm not  
tooo worried about that, because things are broken above.  It looks  
like the call was answered (and it even knows who called it -- cool).   
But, it looks like FreeSwitch doesn't know what to do with the call,  
and so it aborts and hangs up.

I think this is expected behavior.

I want to use FreeSwitch for a few things, but the first is to build  
an IVR and Voicemail system.

Can someone point me to resources or give me some quick tips on how to  
start this?  There appear to be almost hundreds of config files, and  
it's all new to me, so I don't really know where to start, which files  
do what, etc, etc.  If someone could help me with minimal instructions  
on how to play a sound file based on some control-flow code I write,  
or some way to run a script, or whatever, I'd be very grateful.

I'm just really overwhelmed and I don't know how to start.  Thanks in  
advance, very much!

PS: If people help me get rolling, I'm happy to update wikis and/or  
write little tutorials as I go to save this hassle for future...
