Does LiveKit support custom SIP headers for inbound and outbound calls?

This question originally came up in our Slack community and the thread has been consolidated here for long-term reference.

Is there any way to add custom SIP headers for inbound and outbound calls before reaching LiveKit?

I’m using Twilio and Telnyx providers for SIP trunking. I want to use these custom SIP headers for customer details.

Yes, LiveKit supports receiving custom SIP headers from your SIP provider.
