[asterisk-users] wav files are not playing asterisk

[William Stillwell]

Your error is in front of you.

 

format_wav.c:148 check_header: Not in mono 2
[Feb 28 22:27:07] WARNING[2736]: file.c:386 fn_wrapper: Unable to open
format wav



 

Your wav file is not in proper format.

 

Must be mono, and at 8khz, 16bit

 

You can resample by using this command:

 

sox foo-in.wav -r 8000 -c 1 -s -w foo-out.wav resample -ql

 

more info here: (found by using a cool search engine called google and
typing "asterisk wav format"

"dial s" from console it wil play demo files that I can here from headphone
connected to asterisk running system(Android OS).If I play gsm file noise is
coming,but asterisk is not playing wav files,below is the error I am
getting. Where I can see the channels is encodes as GSM,and how to change to
wav.?

know where I need to change to make it works. 


Asterisk chooses a file encoding based on the channel encoding. If your
channel is encoded as GSM, Asterisk will not look for a .wav of the same
name if a .gsm is available. If the .gsm is not available, Asterisk will use
the .wav with the additional 'overhead' of transcoding the data to GSM. 

Without any console log, these are just guesses: 

1) Don't specify the file type in your dialplan. Asterisk chooses a file
type for you based on channel encoding and formatting modules loaded. Is
format_wav.so loaded? 

2) Your WAV file is not encoded correctly. The 'file' command should show
something like 'RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16
bit, mono 8000 Hz' 

3) You have permission issues. From a shell, as the user your instance of
Asterisk runs as, can you access the file? 

If this doesn't help, please repost including the relevant dialplan context
(as displayed by 'dialplan show <relevant-context-name>) and a snippet of
the console log of a call playing the WAV file.
