Hello Happy New Year! I succesfully installed the Ports of Zaptel BSD 1.4.0 and Asterisk 1.4.13 (that's the latest in the Ports). To save CPU, I'd like to play PCM WAV files instead of eg. GSM. Per... www.voip-info.org/wiki/view/Convert+WAV+audio+files+for+use+in+Asterisk ... I recorded a sample of my voice using XP's Sound Recorder, then ran the following : sox test_wav.wav -r 8000 -c 1 -s -w test_wav_out.wav resample -ql But it seems like I'm missing the codec or something: =========== -- Executing [s at default:2] Playback("SIP/2000-0871d000", "/usr/local/lib/asterisk/test_wav_out.wav") in new stack WARNING[37390]: file.c:563 ast_openstream_full: File /usr/local/lib/asterisk/test_wav_out.wav does not exist in any format WARNING[37390]: file.c:866 ast_streamfile: Unable to open /usr/local/lib/asterisk/test_wav_out.wav (format 0x4 (ulaw)): No such file or directory =========== Here's what "core show file formats" says: =========== Format Name Extensions gsm wav49 WAV\|wav49 slin wav wav adpcm vox vox slin sln sln\|raw g722 g722 g722 ulaw au au alaw alaw alaw\|al ulaw pcm pcm\|ulaw\|ul\|mu ilbc iLBC ilbc h264 h264 h264 h263 h263 h263 gsm gsm gsm g729 g729 g729 g726 g726-16 g726-16 g726 g726-24 g726-24 g726 g726-32 g726-32 g726 g726-40 g726-40 g723 g723sf g723\|g723sf 18 file formats registered. =========== Am I missing something in the configuration files, or maybe I'm missing some module?

And asterisk will automatically pickup the file that it can play with any
asterisk supported format from the specified path.

OK. Is there a way to tell Asterisk which codec to use so it doesn't
try figuring out the file format used? Thanks.

The codec is specified (for a sip device) in sip.conf, like this:

[general]
disallow=all
allow=ulaw
allow=alaw
allow=gsm
And you know that you can convert the files to every codec format that
is in use then will the cpu load be minimalized !

To convert between different codec formats can you use the asterisk CLI
command:
file convert <file_in.format> <file_out.format>

To convert from a shell script can you do like this:

#!/bin/bash
# Converts a audio file from alaw to a ulaw
rasterisk -x "file convert /tmp/file_in.alaw /tmp/file_out.ulaw"

More examples:
The old way:
http://www.voip-info.org/tiki-index.php?page=Convert+WAV+audio+files+for+use+in+Asterisk
I will try to update this page with "convert".

As a final touch, I have heard that sln should be the prefered format
where you dont have the same format as the codec used in a channel.
"Asterisk native format is sln"

Asterisk automatically takes care of saving CPU issue as it picks the file
that have less translation cost (in other words it picks the file that gives
the best CPU performance based on call situations like in which codec format
the call is bridged ). That way you don't have to worry about specifying
particular format moreover there is no provision to do that in Playback
application. You can see translation costs by typing the following in
console.

core show translation

Good to know. Actually, I'll have Asterisk save voicemails as WAV and
move the files to the www's htdocs, and send an e-mail to users with
the link they'll just have to click to listen to them.

Actually, I'm thinking of embedding a Flash player in the web page,
and update its playlist file so that the browser doesn't launch the
external app that is registered with Windows to play WAV files. But I
haven't found any Flash player that can play WAV, only MP3 :-/

Yup, but the CPU is just a Pentium 233MHz. I just converted a 20MB WAV
file from a CD-quality (44KHz sample rate, stereo) into the format
Asterisk likes (8HKz, mono), and it took about 10mn. So conversion is
out of the question, as Asterisk is likely to have a problem answering
other incoming calls while it's busy converting the last voicemail
message.

Thanks, I didn't know this command.

Yes, but that's OK for files that I use in the IVR, but not for
voicemail messages. The CPU is too slow to handle
WAV-to-something_more_compact conversion in a timely manner.

Thats true, so I normaly convert files on my development box, don't
wan't to disturb the production. And the conversion of prompts is a one
time task! To "re encode" is a cpu load that happens every time the
prompt is used!

What do you have to gain from using a flash player?

Every web browser that supports a flash addon supports also playing wav
(that is: WAV/RIFF files) files natively. But not vice-versa.

BTW: support for WAV/gsm is also getting more and more common.

Huh?

And you want to encode MP3s on that server? It won't save you *that*
much space either.

By default, unless a plug-in was installed (eg. QuickTime, yuck), if I
click on WAV file in FireFox or IE (Opera is OK), it spawns the
application that registered with Windows to play WAV files. I'd like
to avoid this.

When using a Flash player, it just plays the file without launching an
external app. And users get to see a playlist from which they just to
pick which message they want to hear. Much better:

No, precisely: I _don't_ want to compress files in MP3, I want to keep
them in WAV. The goal is not to save space, but to save CPU Smile

FWIW, I sucessfully flashed the CF card with Askozia, which is based
on FreeBSD + Asterisk 1.4 and is derived from the MonoWall project:

http://askozia.com/pbx/

It runs very nicely on that IBM Netvista sporting a Pentium 233MHz and
256MB RAM.
