<P>Hello all,</P>
<P> </P>
<P>I am trying to play .wav file using asterisk 1.8.7.1. I tried playing the wav files having different properties. </P>
<P>The properties of the file can be seen using 'file' command or 'ffmpeg -i <filename>'</P>
<P> </P>
<P>1. Filname: miss_audio.wav</P>
<P> </P>
<P>[root@localhost en]# file miss_audio.wav </P>
<P><STRONG>miss_audio.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, mono 8000 Hz</STRONG></P>
<P> </P>
<P>[root@localhost en]# ffmpeg -i miss_audio.wav</P>
<P>Stream #0:0: Audio: pcm_mulaw ([7][0][0][0] / 0x0007), 8000 Hz, 1 channels, s16, 64 kb/s</P>
<P> </P>
<P>I am getting the following warning in this case.</P>
<P> </P>

<P>2. Filename: msg0000.wav </P>

<P><STRONG>This file is recorded using asterisk voicemail() application</STRONG>.</P>

<P><BR>And in this case asterisk is trying to play the file in slin format.</P>

<P> </P>
<P> </P>
<P>Why does asterisk start playing the file in slin format. </P>
<P> </P>
<P>I would be thankful if someone can guide me to the steps for playing the wav file in asterisk.</P>
<P> </P>
<P>Regards,</P>
