Telephony
Stream Fallback
Twilio hits this when the <Connect><Stream> ends (timeout, error, or normal disconnect).
If the stream ended normally (the bot hung up via SIP), this is a no-op — just hang up. If it ended abnormally (SIP bridge never happened), send voicemail TwiML and fire a PagerDuty alert (respecting dry-run and environment settings).
