Like many others, I was having issues with streaming via mpg123. I wrote the following script to eliminate the need for mpg123 by using curl and ffmpeg. I hope this helps!

STREAMSVR='http://STREAMURI:PORT'
PLAYER='/usr/bin/ffmpeg'

-i = input file; -ar = audio bitrate; -ac = audio channels; -f = force format
-acodec = output audio codec; -vol is volume, 256 is default and we set it to
3/5 the normal volume.

PLAYERARGS="-i $INFILE -ar 8000 -ac 1 -f mulaw -acodec pcm_mulaw -vol 154 $OUTFILE"

- is the shell operator for stdout, we want to read from it for the curl
output and write back to it for the ffmpeg output.

INFILE="-"
OUTFILE="-"

function playStream() {
curl -s "$STREAMSVR" | "$PLAYER" $PLAYERARGS
}

We have just upgraded to 1.4.20-rc1 and found that the following method to turn off music on hold no longer works, it just reverts to the default moh class which we use for our IVR. Basically we are trying to turn off the MOH for agents and even playing a silence sound file produces noise on the line that you can hear in a quiet environment. Does anyone have any other suggestions?

I had some trouble with the music on hold quality and did the following:
Removed previous MPG123 which was in /usr/local

Installed different version of mpg123
1.) cd /usr/local
2.) wget http://superb-west.dl.sourceforge.net/sourceforge/mpg123/mpg123-0.59r-gpl.tar.gz
3.) tar zxvf mpg123-0.59r-gpl.tar.gz
4.) cd mpg123-0.59r-gpl
5.) make linux
6.) make install

Your etc/asterisk/musiconhold.conf configuration should look like the following:


;
; Music on Hold --
;

[default]
mode=quietmp3
directory=/var/lib/asterisk/mohmp3

Your /etc/asterisk/Zapata.conf should look something like the following:


[channels]
relaxdtmf=yes
;       group 5
;
language=en
signalling=em_w
rxwink=300
switchtype=national
emdigitwait=2000
usecallerid=yes
threewaycalling=yes
transfer=yes
musiconhold=default
busydetect=no          ;leave this on for detecting hangups
;jitterbuffers=10
;echocancel=yes
;echocancelwhenbridged=yes
group=5
channel => 1-24

You should also have at least one MP3 file on /var//lib/asterisk/mohmp3

Be sure to meet any legal requirements for music-on-hold.

I hope somebody with a legal background will comment on this because I really don't know. Are the three mp3 files included in the Asterisk distribution royalty-free or do we need to pay somebody for the right to use them in a production environment? (this is probably documented somewhere but I haven't found it yet) I do know the included files came from www.freeplaymusic.com and that the FAQ there mentions a licensing fee for music-on-hold usage, don't know if this is "grandfathered" for the three included files though. Ideas?

I wanted to have my FAX line to ring instead of music on hold so that it does not confuse any fax machines with the music. Here is what i came up with to change it in my stealth auto attendant:

exten => 111,1,Zapateller(answer|nocallerid)
exten => 111,2,SetMusicOnHold(default)
exten => 111,3,DigitTimeout,3
exten => 111,4,ResponseTimeout,3
exten => 111,5,Background(custom/welcome)

exten => 0,1,Dial(local/420@from-internal,35,m)
exten => 0,2,VoiceMail(420@default)
exten => 0,3,Hangup
exten => 1,1,Dial(local/499@from-internal,20,m)
exten => 1,2,Hangup
exten => 7,1,Authenticate(1234)
exten => 7,2,DISA(no-password|from-internal)

In the Dial lines above (exten => 1,1,Dial(local/499@from-internal,20,m) the last "m" denotes play music while waiting, by simply changing the "m" to an "r" it will pass the regualr ring tone instead of music, like this:

(exten => 1,1,Dial(local/499@from-internal,20,r)

Worked great!

Well, there's plenty of talk about how to turn MOH ON, but I see nothing on how to TURN IT OFF! I'd like to turn it off on certain phones, so as to not put out music when I happen to be on a conference call. But, I'd settle for completely turning it off, if I can't individually control it.

Ideas?

My system is Debian3 running 2.6.7 with Asterisk CVS-HEAD-07/23/04-11:30:06.

For some reason my MOH was never triggered when anyone called either of my 5 queues. I tried all setting I could think off before I turned to the mailing list.

I used some hours on this - so I hope this can help others...

This is a snippet from my mail at the asterisk-users mailing list (Link to archive):

It seems that the script /usr/sbin/safe_asterisk is never replaced when you "make install" in asterisk. While it's nice that your own hacks are preserved, I think it would be a lot nicer to have a warning if that file was updated since your last install - and it could simply backup your existing safe_asterisk and replace it with the updated version.

I did not actually find out the real reason why that safe_asterisk script did not work in the first place. Maybe someone more experienced can answer that better.

Solution: replacing the safe_asterisk with whatever HEAD version I had downloaded last made "everything" (about MOH) work.

Or: Simply run asterisk manually and/or with your own "safe" wrapper.

mpg123 0.59s has broken -f (scaling) processing.

asterisk passes -f 32768 and -r 8000. currently only passing it -f 1 seems to work (to version 0.59s). I have not tested to see if the -r 8000 parameter is part of the problem or not.

asterisk has no current way to change the -f parameter to 1, besides a source code change. I could not find out where the problem lay in mpg123-0.59s, as the changes (between 0.59s and 0.59r) that I spotted seemed benign.

in anycase 0.59r does work with the current asterisk code. I would like to see an overhaul in the MOH options. Like being able to specify your entire commandline (so that you can run OGG files or whatever).

mpg123 version 0.59s sounded bad (too loud, distorted)
Version 0.59r works fine.
