Thanks — I hear you: you expected inbound rooms named like

room_...

but a new room appeared as

sbx-...

and you want to know why. I don’t have a confirmed source that

sbx-

is a standard LiveKit naming pattern. Typical inbound room names come from the

room_prefix

in a dispatch rule (for example

call-...

). To help troubleshoot, could you tell me: • Are you using a sandbox (sbx) or staging environment for this project? • The project ID and the exact room name (you can redact sensitive parts) or the room ID/timestamp when it was created. • Whether you recently changed any dispatch rules, SIP/telephony agent configs, or automation that generates room names. • Any webhook or provisioning service that might programmatically create rooms. With those details I can check your dispatch rules and recent room-creation events and suggest next steps (or identify if an environment or config caused the

sbx-

prefix). Sources: SIP Lifecycle Management Agent | LiveKit docs | Agents telephony integration | LiveKit docs
