I need a solution for just receive a call from a SIP Provider and answer the call automatically with a mp3/wav file.

I've already achieved this using a complex and big PBX solution like Freeswitch, but i feel that is a waste of resources.

Isn't there any simply SIP BOT/Client (for Linux) for just play an audio when a call is coming?

Thanks

You can simplify your big prepackaged PBX solution using just a build of asterisk configured to do only what you want to achieve – hmontoliu Mar 8 '12 at 15:19

Look into OpenSIPS & Asterisk. They are very versatile, and most likely overkill. But free, well supported and most importantly, Open Source.

You could try Voxeo Prophecy. You can download a 2 port version for free that runs on Linux. It is a software based IVR solution that uses SIP as the telecommunications channel. You would have to write a very simple VoiceXML application to run on it that would basically look like this:

<?xml version="1.0" encoding="UTF-8"?> 
<vxml version = "2.1"> 

<form id="F_1"> 
  <block> 
    <prompt> 
    Play prerecorded audio file after answering SIP call
    </prompt> 
    <audio src="MySoundFile.wav"  fetchhint="prefetch"/> 
  </block> 
</form> 

</vxml>

I'd suggest using FreeSWITCH in a stripped-down configuration: you can really minimize it to load only the modules you need, and with a really minimalistic dialplan.

I googled "sip client auto answer play file" and found psjua. A command line SIP client for Linux & Windows which should be able to auto-answer and auto-play files. Never heard of it before and the documentation is from 2007, but seems quite useful.
