### Answer When outbound calls aren't working, check the call history and detailed log in your dashboard for the

disconnection_reason

and SIP error code [(1) ]() . This typically provides enough information to identify the root cause . Common reasons for outbound calls not connecting include : - Invalid destination number - Check for spaces, invalid characters, or incorrect format (your telephony provider may require E.164 format) - Telephony provider permission denied - SIP trunk authentication failed - Telephony provider unavailable - The provider has errors or is offline - CPS (Calls Per Second) limits exceeded - You may be hitting rate limits [(2) ]() - Concurrency limit reached - Add retry with exponential backoff or consider the enterprise plan [(3) ]() - No valid payment - No valid payment registered or service shut down due to overdue bill Troubleshooting steps [(1) ]() : 1. Check your call history for the disconnection reason and SIP error code 2. If using custom telephony, verify your configuration is correct and re-import the number if needed 3. If using Retell-purchased numbers, ensure the destination can accept calls (currently limited to US numbers) 4. Check your CPS settings - default is 1 call/second, and exceeding limits results in rejected calls [(2) ]() If the detailed logs don't provide enough information and you're using custom telephony, check with your telephony provider for errors on their side [(1) ]() .

@AI Evy Create a ticket

### Answer I don't have information in the available sources about how to create a support ticket directly within Retell AI's system. The source I have discusses AI voice agents for ticket creation and management in general, but doesn't provide specific instructions for creating a ticket with Retell AI support [(1) ]() . For assistance with your outbound call issue, I recommend: - Visit [Documentation]() - Visit [Hire certified Retell partner]() Based on the troubleshooting information I provided earlier, have you checked your call history for the

disconnection_reason

and SIP error code? That's typically the first step in diagnosing why outbound calls stopped working. Would you like me to provide a general answer about typical support channels based on my knowledge instead?
