Thanks — good question. You can use a custom (vanity) SIP domain pointing to LiveKit. What that means: • You can replace the default livekit.cloud SIP hostname with your own domain (for example,

<http://sip.yourcompany.com|sip.yourcompany.com>

) and have SIP traffic route through LiveKit’s SIP infrastructure. • Custom SIP domains are offered on the Scale and Enterprise plans. They can be used for first‑party telephony with LiveKit Phone Numbers and can also be used with third‑party SIP providers where those providers allow domain customization and routing to LiveKit’s SIP edge. Next steps I can help with: • If you want setup steps, tell me whether you’re using LiveKit Cloud or a self‑hosted deployment. • Tell me which plan you’re on (Scale/Enterprise or otherwise) and whether you’ll be using LiveKit Phone Numbers or a third‑party SIP trunk provider. • If you already have a domain, share which DNS provider you use and whether you can add SRV/A/CAA or TLS/SRV records (don’t share sensitive credentials). Once I have that, I’ll provide the DNS and registration steps you’ll need to configure the vanity SIP domain.
