Partial Wrapping OpenAI Realtime for voice is easy, but the SIP and IP-PBX connectivity layer is the hard part. Real-time audio transport, codec handling, and interoperability with varied PBX systems need telephony expertise.
What it would actually take: The architecture would combine a SIP stack (such as PJSIP or drachtio), RTP media handling with codec transcoding (G.711 and Opus), and a low-latency bridge to the OpenAI Realtime WebSocket API. Real-world reliability requires telephony engineering knowledge, testing against multiple PBX vendors, and handling NAT, jitter and barge-in.
