Cluster egress goes through a step-ca-fronted TLS proxy that install-sounds
doesn't trust ("SSL certificate problem: self-signed certificate"). The
Asterisk core sounds tarball is a public artifact; integrity is enforced
downstream when Asterisk plays the file.

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.

Phone negotiates RFC4733 but may not actually send telephone-event
RTP packets. Inband detects DTMF from audio stream directly.

Root cause: Yealink AX83H intercepts *0 locally as voicemail access,
never sending it to the SIP server. Fix:
- dialplan.digitmap sends all * codes to server
- DTMF set to RFC2833 for Asterisk ARI compatibility
- Local pickup/voicemail features disabled
- key_as_send enabled for immediate dial

AX83H may send DTMF as SIP INFO instead of RFC4733. Auto mode
accepts both, fixing button press detection in star code menus.

from-twilio: Changed from Dial(PJSIP/100) to Stasis(flowercore-pbx,inbound-pstn)
so inbound calls go through the FlowerCore IVR workflow engine instead
of directly ringing extensions.
Added missing star codes: *43 (echo test), *80 (intercom), *88 (conference),
*41/*411 (directory). Added catch-all _*X. pattern for future star codes.
