Self Hosting

We are trying to understand whether a self-hosted SIP server can work with the LiveKit Cloud dashboard.

Our setup:

We have already self-hosted a SIP server using Docker Compose.

In our configuration (config.yaml / docker-compose.yaml), we provided:

LiveKit Cloud wss_url

api_key

api_secret

We opened ports 5060 and 5061 (and temporarily all ports for testing).

What we tested:

We successfully tested SIP integration using Plivo with the LiveKit Cloud SIP server, and it worked as expected.

However, when switching to our self-hosted SIP server, all calls result in a busy line.

Our question:

Is it actually supported to use a self-hosted SIP server with LiveKit Cloud?

If yes, are there any additional configuration steps required that we might be missing?

We’d appreciate any guidance on:

Required SIP configuration for LiveKit Cloud

Networking/firewall considerations

Any known limitations when mixing self-hosted SIP with LiveKit Cloud

Thanks in advance for your help!
