Delphi v0.9.19 stores each call's SIP ladder and span tree after hangup, shows DTMF digits in the SIP ladder, runs Test Call on a temporary copy of the app, switches Azure speech recognition to the caller's detected language and repairs base numbers with a duplicated country code. It pins a media certificate authority for internal media HTTPS and binds TelPro media to its routed floating address. The upgrade requires operator actions, so read the upgrade notes before you start.

Delphi v0.9.18 splits Browser SDK and browser voice into independent capabilities that each default to off. It adds a team system-audio library, bot no-input handling, per-trunk SIP maintenance mode and structured transaction logging. The upgrade requires operator actions, so read the upgrade notes before you start.

Delphi v0.9.17-patch2 reduced unnecessary work in the SIP edge's periodic reconciliation, added exact searches for structured flow IDs, corrected trunk health probe replies and result storage, and closed remaining audit-display and telemetry-redaction gaps. It also improved targeted AI flow edits, tool-code validation, realtime transcript timing and call transitions, and made error alarm attributes as searchable as informational events. These follow-up fixes were not included in patch1.

Delphi v0.9.17-patch1 improved audio startup, call teardown and custom SIP header handling. It also moved inbound trunk health checks to the SIP edge and improved call searches, timestamps and audit attribution.

Delphi v0.9.17 is a full platform cut after v0.9.16-patch2. It adds a Super Viewer role, per-app recording artefacts, and much tighter hangup, transfer, DTMF, and SIP header behaviour. Operators get a max call duration with a spoken warning, seven.io SMS, hidden production Swagger, AMI trunk-health credentials, and categorized config backups. The list below is the user-visible work from this window, grouped by area — not every internal ticket.

Delphi v0.9.16-patch1 improves media advertisement, speech processing and RTP observability. TelPro media advertisement is clearer for LB/NAT hosts, Azure STT turn races are quieter under load, and RTPEngine final-stat spans expose per-endpoint counters.

This release introduces the AI Flow Builder as the new authoring surface for voice flows, ships the shared @delphi/flow-engine and @delphi/features packages, upgrades the voice stack to Asterisk 22.9.0, broadens AI provider support, and lays the groundwork for managed billing with Stripe checkout, activation, and subscription guards.
