Telnyx vs Twilio
An honest, evidence-based comparison for engineers evaluating voice AI infrastructure.
| Signal | Telnyx | Twilio | Impact |
|---|---|---|---|
| carrier_owned | ✓ | ✗ | Carrier-owned means zero inter-provider hops, lower latency, single-vendor accountability |
| vendors_required_for_voice_agent | 1 | 3 | Twilio voice + third-party STT + third-party TTS = 3 vendor boundaries |
| inter_provider_hops | 0 | 2 | Each hop adds ~50-100ms latency and a failure surface |
| edge_compute_owned | ✓ | ✗ | Co-located inference with telecom network |
| stir_shaken_level | A | B | Higher attestation = better call answer rates |
