Subject: [PATCH] fix(asterisk): actually install core sounds (en, ulaw 1.6.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The install-sounds init container was a stub that left /var/lib/asterisk/sounds/en
empty. Result: every SpeakText fallback path (vm-advopts, vm-goodbye, characters:*,
digits/*, beep, pbx-invalid) resolved to a missing file, Asterisk silently failed
each Playback, zero RTP was produced, and callers heard dead air. This is why
dialing *0 (Settings Menu) or *100 (Debug IVR) "picks up quietly" — there is
literally nothing to stream.

Replaced the stub with alpine:3.20 + curl + tar that downloads the pinned
asterisk-core-sounds-en-ulaw-1.6.1.tar.gz (~10 MB) from downloads.asterisk.org
and unpacks it into the sounds emptyDir. Idempotent — skips download if
vm-goodbye is already present.
