IntelliCall AI

Close leads automatically with AI voice agents that call, qualify, and book appointments — 24/7. Run it as your own SaaS. Keep 100% of the revenue.

What you can do with IntelliCall AI

• Call 1,000+ leads automatically without a sales team
• Qualify prospects in real-time using AI
• Book appointments directly from phone calls
• Choose a voice engine per agent — Classic pipeline, the low-latency Deepgram Voice Agent, or Sarvam AI for native Indian languages
• Run agents in Indian languages (Hindi, Tamil, Telugu, Bengali, Kannada, Marathi and more) on a single Sarvam key
• Personalize every call with custom contact fields (merge tags like {{appointment_date}}) filled in per lead
• Cut no-shows with automatic WhatsApp appointment reminders sent to clients
• Automate everything with n8n + REST API — a form submits, the AI calls the prospect in seconds
• Launch your own AI calling SaaS and charge clients monthly

Who this is for

• SaaS founders who want a real product to sell subscriptions, not a weekend script
• Agencies who can productize AI calling for clients under their brand
• Sales and growth teams that need qualification and booking without a call center
• Operators who want BYOK (bring your own keys) and predictable infrastructure costs

How it works: a real-world flow (step by step)

1. Trigger: a prospect calls your number or your campaign dials a lead list (CSV or Google Sheets).
2. Answer: the AI agent picks up with your opening message and brand voice.
3. Understand: real-time speech-to-text and LLM reasoning keep the conversation on goal.
4. Qualify or support: Knowledge-backed answers move the call forward.
5. Book or hand off: appointments land on your calendar, clients get automatic WhatsApp reminders before the meeting, and hot leads are obvious from scoring.
6. Sync: webhooks, n8n workflows, and integrations push events to your CRM, stack, or internal tools — with real-time alerts on Slack and your own WhatsApp.
7. Review: recordings, transcripts, and summaries give managers proof of performance.

Feature highlights

Voice Quality & Conversation controls per agent — NEW in v10.9

• Voice Quality presets: pick Fast, Balanced, Natural or Expressive per agent — the same ElevenLabs voice can sound like a warm receptionist on one agent and a confident sales rep on another
• Custom / Advanced mode: the raw ElevenLabs per-call controls — stability, similarity boost, style, speaker boost and speaking speed, plus the ElevenLabs model (Turbo v2.5, Flash v2.5 or Multilingual v2) and a latency profile that trades response speed against voice quality
• Turn-taking controls: tune end-of-turn silence, silence tolerance and interruption sensitivity per agent, with built-in protection against false interruptions from coughs and line noise
• More natural speech in every language: prosody-aware speech buffering sends complete clauses to the voice engine instead of cutting at every comma — audibly better intonation, especially in Spanish and other Romance languages
• Voice Quality diagnostics: every call records response latency, interruptions, false voice-detection events and audio buffer stats — visible in Call Log details
• Fully backwards compatible: the Default preset keeps existing agents sounding exactly as before — everything is opt-in, per agent

Multilingual dashboard with full RTL support

• The dashboard and admin panel ship in 5 languages — English, Spanish, French, German and Arabic — switched from the header, with no page reload and nothing lost from a half-filled form
• Full right-to-left support for Arabic: the sidebar moves to the right and the whole layout, tables, menus and drawers mirror, with an Arabic font applied automatically, while phone numbers and email addresses stay readable inside Arabic text
• Every user picks their own language and it is saved to their account, so it follows them to any device they sign in on
• Add your own language without touching code copy the English translation folder, translate it, add one line of config. Anything you leave untranslated falls back to English, so a partly finished language still gives you a working dashboard
• This is the language of the interface — the language your AI agents speak on a call is still chosen per agent

Multiple voice engines — choose per agent — NEW in v10

• Classic pipeline: Deepgram STT → OpenRouter LLM → ElevenLabs TTS, now with a latency tune-up for noticeably faster, more natural back-and-forth
• Deepgram Voice Agent: a single connection handles speech recognition, the LLM, and voice synthesis with server-side turn-taking for roughly 0.5–0.8s voice-to-voice responses — keeps your selected ElevenLabs voice and needs no OpenRouter key (Deepgram-managed LLM)
• Sarvam AI: a fully self-contained pipeline purpose-built for Indian languages (see below)
• Pick the engine right in the agent editor — existing agents are unaffected until you switch them

Native Indian-language agents with Sarvam AI — NEW in v10

• Speech, reasoning, and voice run entirely on Sarvam AI (Saaras STT → Sarvam-M LLM → Bulbul TTS) — built for Indian languages and accents
• Pick a Sarvam language (Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, or Indian English) and a Sarvam voice per agent, with an in-editor voice preview
• Fully self-contained — agents on this engine need only a single Sarvam API key (no Deepgram, ElevenLabs, or OpenRouter). Works on both Twilio and SIP/Asterisk and supports appointment booking

Custom contact fields — personalized calls — NEW in v10

• Add any custom fields to a lead (e.g. appointment_date, service_type) from the Add / Edit Lead dialog or automatically by CSV import
• Reference them anywhere in an agent's Opening Message or System Prompt as merge tags like {{appointment_date}} — filled in per call, so the AI knows each lead's details for the whole conversation, not just the greeting
• Works across the classic and Deepgram Voice Agent engines, on Twilio and SIP — ideal for appointment-confirmation and reminder calls

Completely redesigned landing page — NEW in v10

• A bold, minimal marketing homepage: full-screen sections that alternate your brand primary color with a clean light/dark base, an animated background grid, floating geometric parallax shapes, watermark typography, and smooth scroll-reveal motion
• Feature spotlights with live UI mockups, full dark-mode support, automatic adoption of your custom brand color and app name, and an admin-toggleable self-hosting section

Human-like TTS, premium STT, multilingual agents

• Natural voice output and low-latency transcription for fluid back-and-forth
• Multilingual voice agents with broad language coverage for global campaigns

Leads and AI agents

• Central lead workspace with fields, tags, and automation-friendly data
• Create and manage agents for inbound, outbound, and mixed use cases

Ready-to-use AI agent templates

Appointment booking and knowledge-powered agents

• Book meetings directly from live calls when it makes sense for your workflow

WhatsApp notifications and client appointment reminders

• Real-time alerts on your own WhatsApp — leads, calls, campaigns, and appointments, with per-event toggles
• Automatic WhatsApp reminders to the client’s number before every appointment — template-based (Meta-approved), timezone-aware, and reschedule-safe, so booked meetings actually happen

n8n automation and API access

• Stream every event into n8n and automate with 400+ apps — includes 3 ready-made workflow templates
• Personal API keys with a built-in API reference — instant AI callbacks via POST /api/calls/dial, leads, campaigns, appointments, and call intelligence from any external tool

CHANGELOGS

Version 11.6 | 29 August 2026

- NEW: HubSpot connects with a service key created in your own HubSpot account — no developer app, no app registration, no callback URL
- NEW: Service keys are verified on save, naming the exact missing scope rather than failing silently at sync time
- IMPROVEMENT: Existing HubSpot OAuth connections keep working unchanged, with nothing to reconfigure after upgrading
- FIX: OAuth callbacks now resolve as HTTPS behind a reverse proxy, clearing invalid redirect URL errors on HubSpot, Slack, Google Calendar and Google Sheets
- FIX: The dashboard now ships .env.example, so the documented setup step works on a fresh install
- NOTE: HubSpot ended new public app creation on 23 June 2026 — service keys are the supported path for new installs

Version 11.5 | 29 August 2026

- NEW: Human Transfer — AI agents can now hand live callers to an authorised person or department
- NEW: Configure multiple transfer destinations per agent, each with its own name and phone number, plus a default destination
- NEW: Failed or unanswered transfers return the caller to the same agent with the conversation context preserved
- NEW: Configure ring times and maximum transfer attempts per agent
- NEW: Transfer activity is recorded in Call Logs, including destination, outcome, ring duration, human talk time, and failure reason
- NEW: "Caller Transferred" and "Transfer Failed" notification events for Webhooks, Slack, WhatsApp and n8n

Version 11.0 | 28 August 2026

- NEW: Gemini Live voice engine — one Google model hears, thinks and speaks on the call, so replies come back fast and sound genuinely conversational; selectable per agent on SIP numbers
- NEW: Test any agent live in your browser — click Test on the AI Agents page, talk to the agent through your microphone, and hear exactly how it sounds before it ever calls a customer
- NEW: Live transcript alongside the conversation, so you can read what the agent heard and said while you talk to it

Version 10.9 | 28 August 2026

- NEW: Voice presets for Fast, Balanced, Natural and Expressive speech
- NEW: Advanced ElevenLabs voice, model and latency controls
- NEW: Custom turn-taking and interruption controls
- IMPROVEMENT: More natural multilingual speech and intonation
- IMPROVEMENT: Updated ElevenLabs latency controls
- NEW: Voice quality diagnostics in Call Logs
- NEW: Per-agent ElevenLabs model selection

Version 10.8.2 | 27 August 2026

- NEW: Dial Prefix field for SIP trunks — wholesale carriers that route on a technical prefix (e.g. 999 in front of the number) can now be used for outbound calls; enter the prefix your carrier gave you and IntelliCall dials it exactly the way they expect
- IMPROVEMENT: The Dial Prefix field is empty by default, so every existing trunk keeps dialling exactly as before — only fill it in if your carrier documents a prefix

Version 10.8.1 | 27 August 2026

- FIX: On SIP calls, agent replies longer than about 10 seconds could have a chunk silently cut out of the middle, and playback could sound rushed or skip parts of sentences — buffered speech is no longer discarded, and playback now stays in step with the call for replies of any length
- FIX: Applied the same fix to every SIP voice engine — ElevenLabs (Classic) and Deepgram Voice Agent now use the corrected audio buffering that Sarvam agents received in v10.7
- IMPROVEMENT: Long replies are buffered up to 60 seconds instead of 10, and the limit is now configurable with SIP_RTP_MAX_QUEUE for unusually long agent responses
- IMPROVEMENT: Removed two unused installer scripts that were not part of the documented setup process

Version 10.8 | 25 August 2026

- NEW: The dashboard and admin panel are now available in 5 languages — English, Spanish, French, German and Arabic — covering every screen, button, form and notification your team sees
- NEW: Language switcher in the dashboard header, next to the light/dark toggle — the interface changes instantly, and anything half-typed into a form is kept
- NEW: Full right-to-left support for Arabic — the sidebar moves to the right and the whole layout, tables, menus and drawers mirror, with an Arabic font applied automatically
- NEW: Every user picks their own dashboard language and it is saved to their account, so it follows them to any device they sign in on — also available under Settings → Preferences
- NEW: Add your own language without touching code — copy the English translation folder, translate it, and add one line of config; anything left untranslated falls back to English, so a partly finished language still works
- IMPROVEMENT: Phone numbers, email addresses and API keys stay left-to-right inside Arabic text so they remain readable
- IMPROVEMENT: Around 2,000 lines of unused code removed from the frontend, and only the language in use is sent to the browser, so extra languages don't slow the dashboard down

Version 10.7 | 24 August 2026

- FIX: Sarvam AI agents could take up to 15 seconds to answer a short reply — saying "hello" or "yes" while the agent was still speaking is now answered in about a quarter of a second
- IMPROVEMENT: Sarvam agents now use Sarvam's realtime speech recognition, which returns words while the caller is still speaking — agents fall back automatically if your Sarvam account isn't enabled for it
- IMPROVEMENT: Interruptions now work from what the caller actually said rather than raw sound level — coughs, line noise and background TV no longer cut the agent off, while brief replies like "okay" or "haan" let it finish and are still answered afterwards
- FIX: On SIP calls, Sarvam replies longer than about 10 seconds could have a chunk silently cut out of the middle — buffered speech is no longer discarded, and playback no longer drifts out of sync on long calls
- IMPROVEMENT: Faster first word from Sarvam agents, and the voice connection is restored in the background after an interruption
- NEW: Optional voice-tuning settings for noise rejection and interruption sensitivity, so agents can be tuned to your own phone lines
- NEW: Sarvam preflight check to confirm your Sarvam account is set up correctly for voice calling before you place a call
- FIX: The backend environment template (.env.example) was missing from the v10.5 and v10.6 downloads — restored, and now documents every setting the backend reads

Version 10.6 | 24 August 2026

- FIX: HubSpot connect could fail with "code challenge parameter is missing" — HubSpot's OAuth now includes PKCE (RFC 7636) on the authorization flow
- IMPROVEMENT: Google Sheets and Google Calendar connect buttons now show a clear message instead of erroring when those integrations aren't configured on the server
- FIX: Setup script could write the wrong value into GOOGLE_CLIENT_SECRET during interactive reconfiguration

Version 10.5 | 17 August 2026

- NEW: Sarvam AI models updated — speech-to-text to Saaras v3, text-to-speech to Bulbul v3, chat to Sarvam's current 105B model; agents on deprecated models migrate automatically
- FIX: Sarvam AI voice could cut off mid-word on SIP calls — fixed, along with related causes of the agent going silent mid-reply
- IMPROVEMENT: Unified turn-taking across the Classic and Sarvam engines — brief responses like "yes" or "hmm" no longer interrupt the agent
- FIX: Deepgram Voice Agent calls could disconnect and fail to reconnect mid-call
- FIX: SIP calls could stay stuck as "In Conversation" with inflated duration after the caller hung up — hangup detection is now reliable, and duration is measured from answer time
- NEW: AI agents can now end the call themselves once the conversation is naturally over, on all three voice engines
- NEW: Idle-call detection — a connected call with no speech for 5 minutes now ends automatically

Version 10.0 | 5 July 2026

- NEW: Per-agent Voice Engine selector — pick Classic pipeline, Deepgram Voice Agent, or Sarvam AI for each agent (Agent → Voice)
- NEW: Sarvam AI voice engine for native Indian languages (Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Indian English) — fully self-contained (Saaras STT + Sarvam-M LLM + Bulbul TTS), needs only a single Sarvam API key, per-agent language + voice with in-editor voice preview, works on both Twilio and SIP/Asterisk and supports appointment booking
- NEW: Deepgram Voice Agent engine (low latency) — one connection handles speech recognition, the LLM, and voice synthesis with server-side turn-taking for roughly 0.5–0.8s voice-to-voice responses; keeps your selected ElevenLabs voice; needs no OpenRouter key (Deepgram-managed LLM); native function-calling appointment booking
- NEW: Custom contact fields (personalized calls) — add any lead fields (e.g. {{appointment_date}}, {{service_type}}) from the Add/Edit Lead dialog or by CSV import, then reference them as merge tags in the Opening Message and System Prompt; filled per call so the AI knows each lead's details the whole conversation (works on classic and Deepgram Voice Agent engines, Twilio and SIP)
- NEW: Completely redesigned marketing landing page — bold full-screen sections that alternate your brand primary color with a clean light/dark base, an animated background grid, geometric parallax shapes, watermark typography, smooth scroll-reveal motion, feature spotlights with live UI mockups, full dark-mode support, and an admin-toggleable self-hosting section
- NEW: Latency instrumentation — every conversation turn logs queue wait, LLM first-token, and first-audio timings so you can measure real response times
- IMPROVEMENT: Classic pipeline latency tune-up — smarter end-of-speech detection and turn-taking, ElevenLabs Flash v2.5 for non-English voices, and per-call knowledge-base caching; typical responses 300–900ms faster (about 2× faster overall)
- FIX: Registration-based SIP inbound calls addressed by the trunk username are now routed to the correct agent
- FIX: Speech transcripts were processed twice per result due to a duplicate Deepgram event handler — fixed on both the Twilio and SIP call paths
- NEW: SIP Debug panel on the SIP Trunks page — a Debug button opens Health Checks and Live Logs tabs so you can diagnose SIP/Asterisk problems from the dashboard without SSH
- NEW: Health Checks — one-click diagnostics for Asterisk ARI connection, PJSIP config written and linked, Asterisk CLI access, and per-trunk endpoint / registration / provider reachability, each failed check with a plain-English fix hint
- NEW: Live Logs — real-time stream of SIP events (outbound/inbound calls, trunk rejections with the SIP cause, originate failures, bridge/recording issues, config reloads), auto-refreshing while open
- NEW: SIP scanner protection — auto-detects and temporarily blocks source IPs that repeatedly dial unknown numbers (silent hangup), tunable via SIP_SCAN_BAN_THRESHOLD / SIP_SCAN_WINDOW_MINUTES / SIP_SCAN_BAN_MINUTES
- PRIVACY: SIP debug logs are per-user — each user sees only their own trunk and call events; superadmins see everything
- FIX: Brand primary color now applies site-wide — the Primary Color set in Admin → Branding drives the public landing page, buttons, accents, and highlights (previously saved but the landing page stayed purple)
- FIX: No stock-logo flash — the default logo and favicon are blank so the original IntelliCall branding never appears for a moment before your uploaded assets load
- FIX: Landing page header no longer changes height while the logo loads (logo renders in a fixed-size box)
- IMPROVEMENT: Reset Branding restores the original IntelliCall logos and favicon (kept under /images/originals/) in one click

Version 9.7 | 23 June 2026

- FIX: Email sending issue fixed.

Version 9.6 | 14 June 2026

- NEW: Personal API keys — generate, regenerate, and revoke a long-lived key (stored hashed, shown once) and call the REST API via the X-API-Key header from n8n, Zapier, or scripts
- NEW: Instant AI call endpoint (POST /api/calls/dial) — dial one number with a chosen agent right now, no campaign needed; auto-creates the lead and respects plan call limits
- NEW: Built-in API reference in the dashboard — 12 documented endpoints with parameters and copy-ready curl examples
- IMPROVEMENT: Integrations tab redesigned with sidebar navigation, per-connector logos, and live connection-status indicators
- IMPROVEMENT: OAuth redirects now auto-open the matching integration card

Version 9.0 | 11 June 2026

- NEW: WhatsApp integration powered by the Meta WhatsApp Cloud API — connect with your own Meta credentials, no platform-level app setup required
- NEW: Real-time WhatsApp notifications for lead created, lead qualified, call completed, appointment booked / canceled, campaign completed, and inbound / outbound calls — with per-event toggles
- NEW: Automatic WhatsApp appointment reminders sent to the client's number before every appointment (Meta-approved message templates, configurable lead time from 15 minutes to 24 hours)
- NEW: Reschedule-safe reminders — moving an appointment re-arms the reminder for the new time; cancellations stop it automatically; duplicate sends are impossible by design
- NEW: Timezone-aware reminder formatting — dates and times follow each account's timezone and 12/24-hour preference
- NEW: Built-in test buttons — send a sample alert or your reminder template to your own WhatsApp to verify setup before clients ever receive a message
