Changelog

Calls list: SMS after the call, a recordings filter, and a rebuilt phone view

• See what the caller received: the new "SMS after call" column tells you whether the automatic confirmation went out after a call. Hover or tap the badge to read the message itself, when it was sent, and — if it failed — the reason the carrier gave. Until now that meant opening the call and scrolling its SMS history.
• "With recording" filter: one click narrows the list to calls you can actually listen to. Recordings erased at the caller’s request drop out, because the filter means "there is something to play right now".
• The phone list, rebuilt: what the caller said is visible straight away, and the phone number places the call in one tap. Filters start collapsed behind a single button that shows how many of them are narrowing the list. Nearly four times as many calls fit on a screen.
• Change a status from your phone: "New", "Needs decision" and the rest are now set straight from the list, without reaching for a computer.
• Recording and consent in one place: two columns that repeated each other were merged. A call recorded without the announcement now carries its own marker — that is a legally relevant fact and belongs in plain sight.

Outbound dialing, multi-tenant & landline-friendly

• Outbound calls via conference: Call clients straight from Heilo — the system connects you first, then dials the client while you hear a short hold music. The conference is recorded and transcribed the same way as inbound calls.
• Full recording-consent flow: Outbound calls now ship with a controller/processor disclosure, an acknowledgement timestamp on each profile, and an admin panel to resolve consent disputes.
• Multi-seat accounts: Accounts can now be shared across teammates — owner/admin/member roles, invitation panel, deal-stage kanban with workflows, tasks, plus full per-organization data isolation (RLS).
• Choice of recording notice: Pick the announcement the caller hears from a set of ready-made wordings — per call, or as the default for a number. The voice-over was rebuilt (Brian, neutral tone).
• Call tags and mood detection: AI labels calls by mood (positive/neutral/tense) and dynamics (monologue/dialogue/conflict). Filter the call list by tag.
• Caller SMS with a privacy mode: Per phone you choose whether to send the caller the full voicemail body, just the call subject, or only your own template. Plus an opt-in for "send the SMS even if the caller hung up before leaving voicemail".
• CSV export: Download the full list of calls and contacts as a CSV — filters on the page are respected.
• Landlines and better onboarding: Verify landlines via voice (Heilo will call you and read the code), and configure an alternate mobile for SMS notifications via the same verify popup. The add-phone wizard is also clearer (business vs. my own phone).
• Dark mode: The whole app — dashboard, settings, call details — now supports dark mode.
• 10 call-details UX polish items: Visible "Edit summary" button, an "analyzing…" placeholder while processing, a roomier transcript editor, scroll preservation, colored status badges and other small touch-ups.

Recording Landing, Analytics & Voicemail Polish

• Redesigned Call List: Call rows now show the full transcript inline with a unified phone-handset icon for conversation and listen modes, plus matching badge colors.
• Voicemail Reliability: Disabled finishOnKey on Twilio Record so DTMF tones no longer cut greetings short, hangup after confirmation prompt, warning on overlong greetings, and dates rendered in the user's regional timezone.
• SMS History Filters: Added caller/owner filter and badges to SMS History plus scrolling support when content overflows.
• Admin Toolkit Expansion: New audit log, SMS dashboard, costs view, alerts, and call-quality monitoring in the admin panel.

• Build Performance: Production builds now use Turbopack and skip Sentry source-map uploads on non-production deploys for noticeably faster CI.

Hosted Numbers Wizard, Inbound SMS & Contact Projects

• Hosted Number Provisioning Wizard: End-to-end wizard for ordering a Heilo-hosted Twilio number with PL regulatory address (AddressSid), per-user promo pricing, and clearer Stripe error handling.
• Inbound SMS on Hosted Numbers: Hosted numbers now receive SMS into the inbox with the contact's name shown next to the phone number in message threads.
• Contact Projects & Tasks: New projects (topics) per contact, unified task list across calls, and the ability to pin important calls to a contact.
• AI-Aggregated Tasks & Decisions: Tasks and decisions extracted from individual calls are now aggregated per contact with AI-powered de-duplication and merging.
• Rich Notes with Transcript Highlights: New TipTap-based rich notes editor with inline transcript highlights so you can drop quotes from the call directly into your notes.
• Per-Number Settings UX Refresh: Refreshed expanded per-number settings layout, ElevenLabs recording-notice voice instead of Polly TTS, and a copy-to-clipboard icon next to each hosted number.

Listen Mode & Smart Call Tools

• Hosted Numbers Infrastructure: Foundation for the Heilo-hosted Twilio number model (incoming-only) with safety migrations, paving the way for users to skip the BYON forwarding setup entirely.
• Per-Phone Call Handling Modes: Vertical-tab settings layout (Forwarding → Calls → Greeting → SMS) with per-phone modes — hybrid, voicemail-only, conversation-only, disabled — explained with HTML/CSS flow diagrams that show the real numbers.
• Forwarding Delay Selector: Choose how many seconds Twilio waits before forwarding a call, directly from phone setup.
• Faster Recording Processing: Recording jobs now run inline in the webhook (with the cron as a 5-minute safety net) so transcripts appear within seconds, plus a fix for late-night SMS triggered by the cron.
