Delphi v0.9.17-patch2 reduced unnecessary work in the SIP edge's periodic reconciliation, added exact searches for structured flow and TOBi conversation 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, speech detection (energy and Silero VAD), 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 reduces TOBi callback contention on TelAPI, accepts benign late end-of-conversation acknowledgements, and hardens hangup SIP header delivery. 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.

Delphi v0.9.16 strengthens authentication and Super Admin controls, adds Microsoft Entra SSO, and gives operators config versioning & backups for platform domains. Voice deployments gain SIP trunk health monitoring, richer flow logging, TOBi sensitive-storage controls, and clearer recording/transcript storage behaviour. Integrators should plan for TelPhi SDK 0.1.4.

Delphi v0.9.15-patch3 raises the custom SIP header budget for managed hangup/transfer actions to the VoiceAI Connect 12,000-character limit, and ensures bot-triggered hangup still tears the call down when BYE headers exceed the budget.

Delphi v0.9.15 adds contract-style custom deal subscriptions, automates edge TLS renewal and rolling service refresh, and exposes TTS character consumption to teams and API integrators. Voice operators can now configure TOBi application metadata per bot, and the platform includes several autoscaling and observability improvements.

Delphi v0.9.14-patch3 adds contract-managed billing tools, improves call debugging with a rebuilt Debug tab and SIP export, hardens text/voice handoff, and standardizes operator log-level controls across services.

Delphi v0.9.14-patch1 simplifies flow portability by making provider configuration inline-only. Saved provider records, provider CRUD APIs, and provider reference resolution are removed. The patch also restores Flow Builder UI behavior that regressed during the v0.9.14 merge and completes bot-delay runtime command handling for managed LLM calls.

Delphi v0.9.14 introduces full UI internationalization (English and German), a redesigned resilience and failover system with three-tier configuration (platform → team → flow) and intermediate bot delay comfort actions, three new voice providers (Gemini Live, Inworld, Grok), hard account lockout for security compliance, in-call DTMF collection for TOBi LLM flows, and plan-gated audio preprocessing.
