Carrier-grade telephony at lower per-minute cost than Twilio.
Telnyx is a carrier-grade SIP and voice-API provider with materially lower per-minute pricing than Twilio for most US destinations. Burki ships a first-class Telnyx adapter that handles the WebSocket media path, SIP termination, and number provisioning end-to-end.
A voice AI assistant is only useful when it can connect to the rest of your stack. The Telnyx integration helps Burki fit into the systems your team already uses for calling, transcription, reasoning, speech, routing, or customer data. That means the assistant can move from a demo into a production workflow without forcing you to replace your existing tools.
Burki keeps the integration flexible. You can run one assistant with Telnyx, pair it with other providers for a full voice pipeline, and change providers later if your cost, latency, coverage, or quality requirements change. This is especially useful for teams that need different settings per assistant, region, campaign, or customer segment.
The result is a voice agent that is easier to operate: fewer hard-coded assumptions, clearer provider boundaries, and a pricing model that separates Burki's platform fee from the third-party services you already trust.
Choose Telnyx when call volume is high enough that the per-minute differential matters, or when you want to consolidate with a single carrier-grade provider. For maximum global DID coverage you may still prefer Twilio.

Burki: $0.03/min platform fee. Telnyx: ~$0.005/min inbound, ~$0.007/min outbound (US, varies), plus $1/mo per number. Often 30–50% cheaper than equivalent Twilio routes for high-volume deployments.
