I am trying to play .wav file using asterisk 188.8.131.52. I tried playing the wav files having different properties.
The properties of the file can be seen using ‘file’ command or ‘ffmpeg -i ‘
1. Filname: miss_audio.wav
[root@localhost en]# file miss_audio.wav
miss_audio.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, mono 8000 Hz
[root@localhost en]# ffmpeg -i miss_audio.wav
Stream #0:0: Audio: pcm_mulaw ( / 0x0007), 8000 Hz, 1 channels, s16, 64 kb/s
I am getting the following warning in this case.
[Dec 24 15:08:47] WARNING: format_wav.c:92 check_header_fmt: Not a wav file 7
[Dec 24 15:08:47] WARNING: file.c:376 fn_wrapper: Unable to open format wav
2. Filename: msg0000.wav
This file is recorded using asterisk voicemail() application .
[root@localhost en]# file msg0000.wav
msg0000.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz
[root@localhost en]# ffmpeg -i msg0000.wav
Stream #0:0: Audio: pcm_s16le ( / 0x0001), 8000 Hz, 1 channels, s16, 128 kb/s
And in this case asterisk is trying to play the file in slin format.
— Playing ‘msg0000.slin’ (language ‘en’)
[Dec 24 15:14:10] WARNING: app_playback.c:475 playback_exec: ast_streamfile failed on SIP/phone1-00000000 for msg0000
— Auto fallthrough, channel ‘SIP/phone1-00000000’ status is ‘UNKNOWN’
[Dec 24 15:14:10] DEBUG: channel.c:2679 ast_softhangup_nolock: Soft-Hanging up channel ‘SIP/phone1-00000000’
Why does asterisk start playing the file in slin format.
I would be thankful if someone can guide me to the steps for playing the wav file in asterisk.
