[Freeswitch-users] Unified logging of incoming mobile calls - partial solution for android

20 Nov 2011

      I know many people run/use a PBX of some sort, and I figured I'd share what
I discovered:
I have a mobile phone that gets a lot of calls directly, but I wanted to
log those calls to a CRM.

This is a partial solution.. Android Notifier (
http://code.google.com/p/android-notifier/) is an app that can be installed
on the android and send a UDP message to a server (or also to a desktop
client) when calls come in. The desktop client can launch a website to pull
data for a screen pop of some sort....
It seemed to sometimes lose sync (when wifi went off and then came back..)
but it's got the last 10 messages or so.

I have it send to UDP, and this small node.js script saves
the time-stamped messages to a file. (Note: timestamp is in milliseconds..)

//http://code.google.com/p/android-notifier/wiki/NotificationProtocol
...
//DEVICE_ID/NOTIFICATION_ID/EVENT_TYPE/EVENT_CONTENTS
var fs = require('fs');
var log = fs.createWriteStream("incoming_call_log.txt", {'flags': 'a'} );
var dgram = require("dgram");
var server = dgram.createSocket("udp4");
server.on("message", function (msg, rinfo) {
//  console.log("server got: " + msg + " from " +  rinfo.address + ":" +
rinfo.port);
//  console.log("Got: " + Date.now() + "/" + rinfo.address +"/" +
rinfo.port + "/" + msg);
              log.write(Date.now() + "/" + rinfo.address +"/" + rinfo.port
+ "/" + msg +  "\n");
});
server.on("listening", function () {
  var address = server.address();
  console.log("server listening " +   address.address + ":" +
address.port);
});
server.bind(10600, "YOUR IP");
And you can background and disown it, so it stays running.. after you
launch node.js.
Due to the abnormal method of submitting - not HTTP - I didn't know how to
write anything in another language to do this. I suppose you could do it
with python twisted.

And for a screenpop.. set the desktop notifier to launch:
/home/folder/web.sh "deviceId={deviceId}&id={id}&type={type}&data={data}"

web.sh contains:
...
#!/bin/bash
echo "$*"; #>> /tmp/websh.log; #logging...
var=$*
/usr/bin/chromium-browser "http://website.com/script.php?$var"
Anyway, this is just the basics. Feel free to share how you integrate it.
I didn't see the specs on how to decrypt the signal algorithimically, but
it's part of the desktop app.
