Could you build this?
Partial The dashboard and evaluation reporting can be vibe-coded, but simulating real-time telephony (SIP trunks, WebRTC/LiveKit) with low-latency synthetic callers, audio streaming, and voice interruption injection requires intricate real-time telecommunications infra.
What it would actually take: A production version requires an orchestrator managing telephony gateways (FreeSWITCH/Asterisk or Twilio SIP) connected to high-concurrency WebRTC/LiveKit rooms. Audio pipelines must handle real-time streaming speech-to-speech models or sub-second STT/TTS chains with precise VAD (voice activity detection) to simulate packet loss, jitter, interruptions, and background noise. Deep expertise in VoIP protocols, digital signal processing (DSP), and streaming audio infrastructure is essential.
