Realtime model over sip: Advice for logging agent audio packets
OpenAI Developer Community

There are multiple options.. you can let the sip provider (twillio?) do the recording I suppose. As far as I remember they have two parallel channels so that should be possible.
Or you add a SBC/Media Proxy between OpenAI and the provider and do the recording over there.
