a problem with HangupAsync(AsterNET.ARI.SimpleTestApplicationAsync)

[pavelbunkov4517]

I downloaded your example(AsterNET.ARI.SimpleTestApplicationAsync)
Run it and click "#" , the phrase is not pronounced, and immediately goes off.
Log from asterisk:

- <SIP/201-000000af> Playing 'goodbye.ulaw' (language 'ru')
[2018-01-25 17:27:13] WARNING[22882][C-000000b8]: res_stasis_playback.c:277 playback_final_update: 1516890429.197: Playback failed for sound:goodbye"

But
case "*":
await sender.Channels.PlayAsync(e.Channel.Id, "sound:asterisk-friend");
await sender.Channels.PlayAsync(e.Channel.Id, "sound:goodbye");

work fine.

Asterisk 14.7.5.
