What does WebRTC vs SIP mean for Voice AI?

WebRTC for browser/web calls (free, easy NAT); SIP for phone/PSTN (mandatory for real lines). Most need both, bridged.

Do I need SIP for phone calls in Voice AI deployments?

Yes, always—no shortcuts. PSTN is SIP-native; ignore at your peril.

Twilio NTS for ease; Coturn for control. Test latency first—it's the silent killer.

Chose the wrong protocol for your Voice AI? Brace for six weeks of gateway hell. Here's what production deployments really demand.
