Thanks — I’m responding to your question about whether LiveKit supports passing custom SIP headers when using

CreateSIPParticipant

. Yes — LiveKit lets you include custom SIP headers when creating SIP participants. Use the

headers

field in the

CreateSIPParticipantRequest

to provide any SIP headers you need passed through during SIP signaling. LiveKit preserves those headers when it initiates the SIP requests, so third-party systems (for example, Genesys Cloud) can receive them. If you’d like, tell me: • which specific header names/values you need to send, and • whether you’re using the REST API or an SDK — and I’ll show an example request payload tailored to your setup.
