# WhatsApp Business Calling, Assistant, six providers, web calls

* **Telephony**: **WhatsApp Business Calling** — connect a WhatsApp Business Account (Embedded Signup or credentials), register numbers, and your agents answer WhatsApp calls with no telephony charge. The same digits can exist as a phone line and a WhatsApp number. See [WhatsApp Business Calling](/telephony/whatsapp-business-calling).
* **Builder**: The **Talkif Assistant** — a chat in the dashboard that answers questions about your account, proposes flow edits as reviewable diffs, and builds a complete flow from a description.
* **Models**: Six new providers — Google Gemini TTS, Google Cloud STT, xAI Grok STT and TTS, Amazon Transcribe, Rime TTS — and the LLM catalogue refreshed with official pricing. ElevenLabs voice browser gains gender, age, language and accent filters; shared-library voices can be added to your account.
* **Integrate**: **Web calls** — put a voice agent on any web page with a publishable key and the browser SDK; and a **real-time events WebSocket** for account-wide and per-call events. See [Real-time events](/integrate/real-time-events).
* **Calls**: Failed calls carry the carrier's real failure code and reason instead of a generic *failed*.
* **Calls**: Honest interruption accounting — the transcript shows what the caller actually heard, and wasted (generated but unspoken) TTS characters are reported per call. Per-contact call timeline; call history gains phone/name search, provider filter, lead filter and server-side sorting.
* **Calls**: Timezone-honest schedules — pick an IANA zone, preview in local time, default to the contact's zone. See [Schedules](/calls/schedules).
* **Builder**: End Call as a shared canvas node; provider nodes auto-connect to the Main Agent when dropped; per-flow turn-taking configuration.
* **Billing**: Trial credit, coupons and promotional balances; Assistant usage with a free monthly allowance, then billed to balance.
* **Meta Lead Ads**: Leads grouped under auto-created campaigns; dataset picker instead of pasting an ID; per-lead attempts, manual recall and a clickable funnel; moved to Call Center → Meta Leads.
