Yours stack. Our voice AI

Built to connect—without the integration headache

Most teams don’t struggle with AI—they struggle with wiring everything together. Telephony setup, provider keys, CRM data, routing logic, and post-call workflows often turn into weeks of custom work. Sayin.ai keeps it simple. Bring your own AI providers, connect your carrier via Elastic SIP (or use Twilio/Vonage), and plug into your business systems with webhooks and APIs. So you can launch fast, pass context into every call, and push outcomes back into your stack—without custom engineering.

AI Engines (STT / TTS / LLM)

Choose the best providers for accuracy, voice quality, latency, and cost.

Telephony & Numbers

Use Twilio/Vonage or connect any carrier via Elastic SIP.

Business Systems

Sync with CRMs, helpdesks, schedulers, and internal tools.

Webhooks & APIs

Route inbound calls, push outcomes post-call, and trigger workflows reliably.

Integrations

Built to plug into your stack

Connect Sayin.ai to what you already use—your AI providers, your phone carrier, and your business tools. Pass the right context into every call, and send outcomes back automatically using webhooks and APIs. No heavy setup. No custom engineering.

  • BYOK AI providers
  • Elastic SIP compatible
  • Webhook retries & delivery logs

AI Engines: Speech-to-Text, Text-to-Speech, and LLMs (BYOK)

Choose your AI stack—don’t get locked in

Sayin.ai supports a flexible AI engine layer. You can select providers per agent (and evolve over time) to balance quality, latency, and spend.

Speech-to-Text (STT)

  • Deepgram — Real-time, high-accuracy transcription for production calls
  • Sarvam.ai — Strong Indian language + accent support for regional use cases

Text-to-Speech (TTS)

  • OpenAI TTS — Natural, consistent voices
  • Rime — Voice variety and performance options
  • ElevenLabs — Premium, high-realism voices for brand-sensitive interactions
  • Sarvam.ai TTS — Regional Indian language voice output

LLM

  • OpenAI GPT models with prompt controls and per-agent settings (model selection, behavior, tone)

Telephony & Numbers

Deploy globally with carrier flexibility

Sayin.ai abstracts the complexity of telephony so you can launch inbound and outbound voice workflows without SIP headaches.

Twilio (number purchase + attach agent)

  • Search/buy numbers inside the platform (where supported)
  • Attach numbers to agents for inbound and outbound caller ID
  • Track calls and usage tied to each number

Vonage (sub-account architecture)

  • Per-customer isolation using sub-account patterns
  • Helps with governance, debugging, and enterprise rollouts
  • Supports numbers + routing similar to Twilio

Elastic SIP (bring your own telephony provider)

  • Connect to any telephony provider via Elastic SIP
  • Retain flexibility and cost control while deploying globally
  • Ideal for enterprises with existing telecom contracts

Business Systems & Workflow Integrations

Connect to the tools your team already uses

Whether you run customer support, sales outreach, collections, or scheduling, Sayin.ai integrates cleanly into the systems you already depend on.

Common categories

  • CRM & sales tools (lead context, customer records, outreach workflows)
  • Helpdesk/ticketing (case lookup, status updates, callback automation)
  • Scheduling tools (booking, confirmations, rescheduling)
  • Internal systems (order status, eligibility checks, account data)

Open Integration Model

If it has an API, Sayin.ai can use it

Sayin.ai includes an open integration model that lets you define HTTP tools and business logic—so voice agents can take action mid-conversation.

What you can do

  • Call external APIs (GET/POST/etc.)
  • Pass variables dynamically (name, time, ticket ID, amount due)
  • Map responses back into the conversation
  • Trigger workflows (create ticket, update CRM, book appointment, check account info)

Tool invocation with argument passing (LLM-driven)

The agent can invoke tools with structured arguments at runtime—so it can do real work, not just respond with text.

Example actions (cards)

  • Check order status
  • Book an appointment
  • Fetch customer plan details
  • Create a ticket and send confirmation

Webhooks: Routing Inbound Calls + Post-Call Automation

Make calls programmable—before and after every conversation

Sayin.ai webhooks let you inject context, route calls to the right agent, and push structured outcomes into your stack.

Inbound call webhook (pre-call)

  • Route calls to the right agent (based on number, time, customer ID, etc.)
  • Inject session variables before the agent speaks
  • Block or redirect calls based on rules

Post-call webhook (agent-specific)

  • Receive call metadata, variables, recording link, and outcomes immediately
  • Sync back to CRMs/helpdesks/data stores
  • Trigger follow-up workflows automatically

Reliability: webhook retries & delivery logs

  • Automatic retries on timeouts and server failures
  • Delivery status logs for auditability and debugging
  • Helps prevent silent integration failures

Multi-Channel Triggers (Optional)

Trigger follow-ups beyond voice

Voice doesn’t have to be the final step. Sayin.ai can trigger messages automatically.

  • SMS reminders and confirmations
  • WhatsApp alerts
  • Email follow-ups
  • Internal notifications (via webhook tools)
