Using Custom Domain for SIP URI on LiveKit Cloud Instead of sip.livekit.cloud

Hi LiveKit team,

We are currently using LiveKit Cloud for our voice agent setup and need to share a SIP address/URI with our customer so they can configure their SIP connection from their side.

At the moment, LiveKit provides SIP URIs in this format:

sip:<id>.sip.livekit.cloud

We wanted to check whether it is possible to use a custom domain/subdomain instead, such as:

sip:<id>.sip.mydomain.com

This would help us provide a more branded and customer-friendly SIP endpoint.

Is custom domain mapping for SIP URIs supported on LiveKit Cloud? If yes, could you please guide us on the required configuration steps?

Thanks in advance.
