Integrations

Connect SignalWire to third-party voice AI platforms and telephony systems.

Available Integrations

LiveKit

Route PSTN calls between SignalWire and LiveKit for real-time audio processing and AI pipelines.

• LiveKit Inbound — Route incoming SignalWire calls to LiveKit
• LiveKit Outbound — Initiate PSTN calls from LiveKit via SignalWire

VAPI

Use SignalWire as the telephony layer under VAPI AI assistants.

• VAPI Inbound — Route incoming SignalWire calls to VAPI agents
• VAPI Outbound — Initiate PSTN calls from VAPI via SignalWire

How It Works

All integrations use SignalWire's SWML connect verb to bridge calls between SignalWire's PSTN infrastructure and third-party SIP endpoints. The pattern is:

1. Assign a SignalWire phone number to a SWML script
2. The SWML script uses connect to bridge to the external SIP address
3. The external platform handles AI processing and returns audio
