Platform capabilities
Everything you need to run voice AI at scale
A vertically integrated platform — from carrier connectivity to LLM orchestration to observability. No stitching together five vendors.
Multi-Carrier Phone Numbers
Provision numbers via Telnyx, Twilio, or your own carrier. Route inbound calls to any agent with flexible SIP_PRIMARY, TEXML_ONLY, and hybrid modes.
Custom Tool Execution
Give agents real-time access to your systems. Define JSON Schema inputs, auth headers, request templates, and timeout policies — no code required.
Context Providers
Enrich every call with live CRM data, schedules, or business rules before the first word is spoken. Chained providers execute in deterministic order.
Call Event Webhooks
Trigger downstream workflows on call started, ended, or transcribed. Per-event filtering, retry logic, and signed payloads built in.
Full Observability
Searchable call transcripts, structured audit logs, per-agent call history, and real-time status. Every event is captured and queryable.
Quick start
From zero to live call in four steps
- 01
Configure an Agent
Define your agent's identity, system prompt, LLM model, voice, and language. Set context variables and connect tools in minutes.
- 02
Provision a Phone Number
Link a number from Telnyx, Twilio, or your own carrier. Choose SIP or TEXML transport and assign your agent.
- 03
Connect Your Data
Attach context providers to enrich calls with live CRM data. Add tools so the agent can query APIs and trigger actions mid-call.
- 04
Go Live
Your agent answers calls in real time. Transcripts, durations, and full call records are captured automatically.
Carrier connectivity
Dual-transport architecture
Connect via enterprise SIP for ultra-low latency, or use TEXML for drop-in Twilio compatibility. Mixed deployments supported on every phone number.
SIP
Session Initiation Protocol
Low-latency, enterprise-grade. Connect directly to your existing PBX, SBC, or carrier SIP trunk.
TEXML
Telnyx XML (Twilio-compatible)
Drop-in Twilio TwiML compatibility. Migrate existing applications without carrier-level changes.
Built for engineering teams
Enterprise-grade technology stack
Every component is designed for reliability, multi-tenancy, and observability. The control plane is fully API-first — anything in the UI is also available via REST.
