ARI Playback via URL fails at v18

[philipptrenz]

Hey there,

I'm currently testing Asterisk with ARI and audio playback via URL. I'm using mono WAV files with 16bit PCM and a sampling rate of 8kHz. I started with Asterisk 15 using the andrius/asterisk:15.x Docker image and everything works fine. I updated to andrius/asterisk:17-current and still no issues.

After that I wanted to update to the next LTS using the andrius/asterisk:glibc-18.x image, but with that asterisk refuses to play my file with the following outputs:

asterisk_1   \| [Mar 12 20:38:18] WARNING[106][C-00000001]: file.c:789 ast_openstream_full: File https://example.com/8c22dd75.wav does not exist in any format 
asterisk_1   \| [Mar 12 20:38:18] WARNING[106][C-00000001]: file.c:1262 ast_streamfile: Unable to open https://example.com/8c22dd75.wav (format (alaw)): Invalid argument

I would like to investigate that further and would be very happy for any hint. Thanks!
