Frequently Asked Questions
What's the cost difference hiring WebRTC vs traditional agencies?
CelloIP developers start at $25/hr vs $80-150/hr for agencies. Same expert knowledge, 50-70% savings without markup overhead.
Do you support older browsers without WebRTC?
Yes. Our developers can implement fallback solutions with Flash, Flash plugins, or adapter scripts. Modern solutions focus on WebRTC-first with graceful degradation.
What's required for a TURN server in production?
coturn is standard. Our backend engineers deploy and optimize it for your scale. Expect 10-30% of calls needing TURN relay. We use Twilio NTS for credential management.
SFU vs MCU - which architecture should we use?
SFU (Mediasoup) scales better and uses less bandwidth but requires client-side mixing. MCU centralizes mixing. SFU recommended for 3-100+ participants.
Can WebRTC applications be HIPAA compliant?
Yes. Requires DTLS-SRTP encryption, BAA agreements, and audit logging. Our developers implement all necessary compliance patterns.
How do we integrate WebRTC with our legacy SIP system?
Via WebRTC gateway (Janus, Kamailio) that bridges browser calls to SIP trunks. Setup typically takes 2-3 weeks depending on your infrastructure.
What hourly rate should I expect for a WebRTC developer in 2026?
WebRTC developer rates: $120–$200/hr in the US/UK, $25–$55/hr in India for equivalent expertise. CelloIP's WebRTC engineers start at $25/hr (mid-level) up to $55/hr (senior SFU/TURN architects) — full-time staff with production WebRTC deployments, not marketplace freelancers.
What skills should a WebRTC developer have?
A strong WebRTC developer knows: ICE/STUN/TURN and coturn configuration, SDP offer/answer negotiation, DTLS-SRTP, SFU architecture (Mediasoup, Janus, LiveKit), getUserMedia/RTCPeerConnection APIs, signalling server design, SIP.js for SIP gateways, and codec handling (Opus, VP8/9, AV1). Ask them to explain why TURN is needed to test depth.
How quickly can a WebRTC developer start?
CelloIP WebRTC developers onboard in 48 hours — NDA Day 1, access provisioned within hours, contributing to your WebRTC stack by the end of the first day.
