I'm doing some more testing with various codecs. I'm seeing some more
weirdness with the selection of a codec by file extension. I'm testing
this on FreeSWITCH trunk 10270.

The following script works with the .wav and .gsm extension, but
everything else seems to fail.

Using lowercase names (such as .g722) fail when recording with a "[ERR]
switch_core_file.c:66 switch_core_perform_file_open() Invalid file
format [g722] for [/tmp/recording.g722]!". Which is fine, I can use
uppercase, but then that plays back garbled audio.

This script should beep, record until you stop speaking, beep again,
pause, beep, playback, beep, hang up.


var allDigits = "";
function on_dtmf(session, type, obj, arg)
{
try {
if (type == "dtmf") {
allDigits += obj.digit;
console_log("info", "DTMF digit: " + session.name + " [" +
obj.digit + "] len [" + obj.duration + "]\n\n");
}
} catch (e) {
console_log("err", e + "\n");
}
return true;
}


// .gsm works, .wav works
//filename = "/tmp/recording.gsm"
//filename = "/tmp/recording.wav"

// These all result in garbled playback
//filename = "/tmp/recording.GSM"
filename = "/tmp/recording.G722"
/filename = "/tmp/recording.SPEEX"
//filename = "/tmp/recording.LPC"
//filename = "/tmp/recording.PCMU"
//filename = "/tmp/recording.PCMA"
//filename = "/tmp/recording.AMR"



session.waitForAnswer(10000);
session.execute("sleep", "2000");

console_log("info", "*****BEGIN*****");
session.execute("gentones", "%(500,0,800)");
rtn = session.recordFile(filename, on_dtmf, "", 240, 500, 3);
session.execute("gentones", "%(500,0,800)");
console_log("info", "*****END*****");


session.execute("sleep", "2000");
session.execute("gentones", "%(500,0,800)");
session.streamFile(filename);
session.execute("gentones", "%(500,0,800)");

session.execute("sleep", "1000");
session.hangup();

When you're doing a playback with the native codecs you shouldn't put
any extension on it. It will automagically select the file based on
the current codec of the channel.

filename = "/tmp/recording"

Then have a file with all the codecs you support then FreeSWITCH will
pick the right one.
