We ship new features regularly to enhance your AI calling experience. ### 📅 Multi-Calendar Support for Assistants We’ve added **Multi-Calendar Tools**, making scheduling smarter and more flexible than ever. ### What’s new: * 🧑‍🤝‍🧑 **Team & Service Calendars** – Assign different calendars to the same assistant, perfect for businesses where customers choose a specific team member or service (e.g. hair vs. nails in a salon). * 🩺 **Medical Appointments Made Easy** – Patients can now book directly with the right doctor’s calendar, streamlining scheduling in clinics and practices. * 🔄 **Seamless Management** – Assistants handle multiple calendars effortlessly, reducing back-and-forth and ensuring accurate bookings every time. This update makes your AI assistants even more versatile, whether you’re running a **salon, clinic, or service team**. ### 🔀 Dualplex Assistant Mode (Beta) Image We’re excited to introduce **Dualplex Mode**, our newest and most powerful assistant experience — combining the best of both worlds from **Speech-to-Speech** and **Pipeline** modes. ### What’s new in Dualplex Mode: * 🎤 **Speech-to-Speech Intelligence** Leverages the advanced **STT + LLM stack** from our Realtime models for natural, fluid conversations with ultra-low latency. * 🔊 **Premium Voice Output** Uses **ElevenLabs TTS**, bringing high-quality voices and voice cloning capabilities directly into the experience. * ⚡ **Best of Both Modes** Seamlessly blends the responsiveness of Speech-to-Speech with the flexibility and voice quality of Pipeline. ### Why it matters: Dualplex gives you the **most realistic AI voice interactions yet**, making conversations smoother, more human-like, and easier to integrate into production environments. ⚠️ **Note:** Dualplex is currently in **beta**. We’re gathering feedback and improving quickly — try it out now and let us know what you think! ### 🗣️ GPT-5 Realtime Speech-to-Speech Image We’ve rolled out major improvements to enhance speed and conversation quality across the platform: * 🗣️ **GPT-5 Realtime in Speech-to-Speech Mode** – Natural, fluid conversations with ultra-low latency for voice interactions. * ⚡ **GPT-5 Mini & Nano in Pipeline Mode** – Optimized for minimal reasoning effort, delivering faster response times and smoother call flows. ### 🧠 Campaigns just got smarter We’ve added powerful new controls to help you get more out of your outbound campaigns, avoid wasted calls, and make sure every lead gets the attention it deserves. Here’s what’s new: ### **1. Campaign Call Status Options** You now have **three new controls** at the campaign level to fine-tune how your leads are called: * **Retry until goal completed** *Continue calling until the goal is achieved.* Perfect for situations where a lead answers but doesn’t complete the desired action (e.g., no appointment booked). Calls will continue until the selected **goal variable** is marked as true. * **Retry on voicemail** *Continue calling until a human answers (skip voicemails).* If a call hits voicemail, the lead won’t be marked as completed — the system will retry until someone picks up. * **Goal variable** *Variable that must be true to mark lead as completed.* Select from your variables which one determines a “completed” lead. If the variable is false, the lead will be retried instead of being marked as completed. ### **2. Update Lead Data/Status from Automation Platform or API** You can now **update lead details and statuses directly from your connected automation tools or API calls**. * Change lead status (e.g., “created” instead of “completed”) dynamically. * Push updated information into your campaigns without manual edits. ### **3. Ringing Timeout in Assistant Settings** A new **ringing timeout** option in the Assistant settings lets you control how long to wait for an answer before moving on. * For outbound campaigns, set it **lower** to avoid voicemail and save agent time. * For campaigns with slower-answering customers, increase it to give them more time to pick up. ### 🚀 GPT-5 Integration Image Experience the most advanced AI yet — faster, smarter, and more accurate responses now power your workflows. New paramters for adjusting reasoning effort will be added shortly. Right now the default value makes it very smart but slow. ### 📞 DTMF Input Tool Image Easily send keypad inputs during outbound calls, enabling smooth navigation through IVR menus and automated workflows. ### 📋 Leads kanban board Image Added **Kanban view** to the Leads section for a more visual workflow. You can now drag and drop leads between stages, quickly update statuses, and track progress at a glance. ### 📚 Knowledgebase search & improved management Image Knowledgebases have just been improved. Now you can: * Search within your knowledgebase documents * Delete an individual document. This is useful when you want to update a small part of an info without having to replace the whole knowledgebase * View all the ingested chunks in each document ### 📲 Make phone call action in automation platform Image Added a new *“Make Phone Call”* action that instantly dials a single number as soon as the API endpoint is invoked—no campaign setup required. Perfect for one-off or time-critical calls, while campaigns remain the recommended solution for bulk calling lists. You can find this action in the automation platform or API. ### 👥 Secondary contacts on leads Image You can now attach multiple backup contacts to every lead. When the primary contact doesn’t answer, calls automatically cascade to the next contact in the list. Add, reorder, or remove secondary contacts from the lead details panel for smoother outreach and higher connect rates. ### 📶 Stable SIP proxy server Customers that used "Outbound SIP proxy server" for their outbound SIP trunk connections to come from a fixed IP, can now switch to the new stable server which offers better connection and stability as this feature was previously in beta. If you used this feature before the update, you will see a button to migrate to the new server from the SIP trunk interface. *Make sure to allow in your PBX/VoIP provider the new IP which you can find in the same SIP trunk interface dialog from phone numbers page.* ### 🌍 Multi-lingual assistants Multi-lingual assistants configuration interface Assistants can now speak multiple languages in the same conversation by setting up "secondary languages" in assistant settings first tab.
