To resolve issues with inbound calls not creating rooms via dispatch rules, follow these steps to systematically identify and fix the problem: • Verify Inbound Trunk Configuration: Ensure your inbound trunk is set up with the correct phone numbers,

auth_username

, and

auth_password

that match your SIP provider’s configuration. • Check Dispatch Rules: Confirm that you have a dispatch rule associated with the correct trunk and that it matches the called number. Use

lk sip dispatch list

to review your rules. • Phone Number Format: Make sure the phone number in your trunk configuration matches the format used by your SIP provider (including the leading

+

if required). • IP Address Restrictions: If you have

allowed_addresses

set, ensure your SIP provider’s IP addresses are included. An empty list allows all IPs. • SIP Provider Routing: Double-check that your SIP provider is routing calls to the correct LiveKit SIP URI and endpoint. For diagnostics, you can: • Run

lk sip inbound list

to verify your inbound trunk exists and is active • Run

lk sip dispatch list

to confirm dispatch rules are present and correct • Review your SIP provider’s logs for any routing or authentication errors If you are using PIN-protected rooms, ensure the dispatch rule includes the correct PIN configuration and that callers are prompted to enter the PIN. Systematically check each of these areas to identify where the workflow is breaking. If you need more targeted troubleshooting, please provide details such as your trunk and dispatch rule configuration, the phone number being called, and any error messages or logs from your SIP provider.
