Asterisk can't find the sound files

KBennett · March 6, 2012, 5:42am

Hello,

I can’t figure out why Asterisk can’t find the sounds files it recorded to playback. I’ve run the script on another server (Asterisk 1.8-r332699) and it ran just fine. I’ve created the files on the new server, changed the permissions and the directory paths. I can’t see what I’m missing.

I appreciate any insights!

Your CLI output states that the file variable is empty therefore the Read command is failing because it is getting only a directory with no file. Check that your ’ /etc/asterisk/random.sh’ script is working properly.

Are the other sounds in the menu playing properly?

KBennett · March 6, 2012, 4:06pm

Hi dalenoll,

I noticed that as well. The random.sh script does work properly. My other sounds are playing. It’s puzzling.

dalenoll · March 6, 2012, 4:31pm

Can you post the shell script?

KBennett · March 6, 2012, 5:04pm

Sure…

#!/bin/bash

files=(.gsm) # Or .gif, or *

n=${#files[@]} # For aesthetics

xmms – “${files[RANDOM % n]}” # Choose a random element

shuf -n1 -e *

ls -l shuf -n l

#find . | shuf -n1

cd /var/lib/asterisk/sounds/depo
a=(*); echo ${a[$((RANDOM % ${#a[@]}))]}

dalenoll · March 6, 2012, 6:37pm

Ok. I put your script on my server and tested with the existing files in the /var/lib/asterisk/sounds/en directory.

It didn’t work… fr a couple of reasons.

The script returns the filename including the extension. This is considered wrong in Asterisk. The filename should not have an extension(for Read, Playback and Background) and it will look at the different file formats and play the most appropriate one.
The echo command includes an embedded ‘newline’ character which the SHELL() function is including in the value. So the file name that was being requested was ‘filename.ext\n’.

I made the following change to the last line of your script and it started working for my testing.

Now that does not answer why you are getting a blank value in the variable.

Here is my version of the ‘randomfile.sh’

#!/bin/bash
# files=(*.gsm) # Or *.gif, or *
# n=${#files[@]} # For aesthetics
# xmms -- "${files[RANDOM % n]}" # Choose a random element

# shuf -n1 -e *

# ls -l shuf -n l

#find . | shuf -n1

cd /var/lib/asterisk/sounds/en
a=(*); echo -n ${a[$((RANDOM % ${#a[@]}))]} | sed 's/\.[a-z]*$//'

Here is my dialplan that I used for testing

exten	=> 650,1,NoOp(Testing SHELL)
 same	=> n,Set(file=${SHELL(source /etc/asterisk/randomfile.sh)})
 same	=> n,NoOp(File: ${file})
 same	=> n(playback),Playback(/var/lib/asterisk/sounds/en/${file})
 same	=> n,Read(choice,/var/lib/asterisk/sounds/en/${file},1)
 same	=> n,NoOp(Choice: ${choice})
 same	=> n,hangup()

I hope this helps

Hello,

I really appreciate you taking the time to look at this, revise the script and to try it out yourself.

In regards to #1, I have the line

   same => n,Set(file=${file:0:12})

to truncate the extension off the filename. I know that Read, Playback and Background don’t like them.

In regards to #2, I did amend my shell script as you outlined, commented out the line mentioned above, and still not luck.

I even tried your dialplan and this is what the CLI gave me ---->

I’m not sure if that’s related.

I even changed the permissions on the parent directory (no luck), moved the file to a different directory (same directory as the sample sound files) and still no luck.

I’m lost. Is it related to the install, perhaps?

dalenoll · March 6, 2012, 11:22pm

It is odd. When I see odd things happening that I have not other explanation I ask ‘Is SELinux turned on?’

KBennett · March 7, 2012, 2:29am

No…it’s turned off.

I’m running this on Rackspace.

dalenoll · March 7, 2012, 2:45am

Heck. It was worth a shot.

OK. Can you ‘su - asterisk’ on the box? (of course, if asterisk is running under some other username, use it instead)

Can you cd into the directory where the audio files are as this non-root user?

If you can can up ‘od’ one of the files in question?

If that works, then I have to go back to the script which may not be returning the a value. Can you source the script as the non-root user? Does it do what is expected?

How about you change the dialplan and instead of ‘source’ the script into the shell that Asterisk creates, feed it into a new subshell by calling like this: Set(file=${SHELL(bash /etc/asterisk/randomfile.sh)})

KBennett · March 7, 2012, 4:28am

I tried everything you suggested. I could see the sound files as a non-root user, and run the script properly.

BUT, when I changed the “source” to “bash”, everything worked as before!!!

Hooray!!! Thank you!

dalenoll · March 7, 2012, 11:51am

Glad to hear it is working. Happy to be of service to you.

The SHELL() function must be calling a different shell than bash.

Make me want to do a Set(shell=${SHELL(echo $SHELL)})
