Jens Bürger updated ASTERISK-26086:
-----------------------------------

    Description: 
On a freshly compiled Asterisk 13.9.1 with example configuration, streaming MoH in wideband (16 kHz) only leads to an screaming noise.
When playing in 8 kHz, streaming works fine::
Excerpt from musiconhold.conf:
[streamtest]
mode=custom
application=/usr/bin/mpg123 -q -r 8000 --mono -s http://mp3.theradio.cc

When streaming in wideband like this:
[streamtest]
mode=custom
format=g722
application=/usr/bin/mpg123 -q -r 16000 --mono -s http://mp3.theradio.cc

The client hears only a screaming noise.

In contrast, when playing a local file which was resampled with sox to 16 kHz, this works fine.

This was verified with two different clients (Snom 370 hardware phone, Jitsi soft phone)
