I'm sorry to hear you're experiencing issues with outbound calls to certain numbers. The "twilio-failed-to-connect-call" error typically indicates a problem that could be on Twilio's side or an issue with the numbers you're trying to reach. Here are a few steps you can take to troubleshoot and potentially resolve the issue:
1. Check Twilio Status: Visit the Twilio Status page to see if there are any ongoing issues that might be affecting your service.
2. Review Call Logs: Look at the detailed call logs in your Twilio account for the failed call IDs to see if there are any error messages or codes that can provide more insight.
3. Verify Number Format: Ensure that the numbers you're trying to call are in the correct E.164 format, which includes the country code, area code, and phone number.
4. Check for Restrictions: Some numbers may have restrictions that prevent them from receiving calls from certain services or countries. Verify if the numbers you're calling have such restrictions.
5. Test with Known Working Numbers: Since you have a working call ID with a different phone number, try testing other known working numbers to see if the issue is isolated to specific numbers.
6. Contact Twilio Support: If the issue persists and you're unable to find a resolution, reaching out to Twilio Support with the call IDs and any error information you have can help them assist you further.
If you need assistance with any specific VAPI functions or have further questions, please let me know, and I'll be happy to help!

How prevalant are these restrictions preventing the service from doing an outbound call?
@codeman3786
Restrictions that prevent outbound calls from being completed can vary widely and may not be very common, but they do occur. Here are some factors that could lead to such restrictions:
1. Carrier Restrictions: Some carriers may block calls from certain services or countries due to spam prevention measures or international calling restrictions.
2. Do Not Call Lists: Numbers on do-not-call lists may reject calls from automated systems or unknown numbers.
3. Number Validity: The number being called might be disconnected, invalid, or entered incorrectly.
4. Country-Specific Rules: Different countries have various regulations that could impact the ability to complete calls to or from their jurisdictions.
5. Twilio Restrictions: Twilio itself may have certain limitations in place, such as restrictions on calls to high-risk numbers or those associated with fraudulent activities.
6. Account Limitations: Your Twilio account may have limitations or permissions that need to be adjusted to allow outbound calls to certain types of numbers or destinations.
While these restrictions can affect outbound call completion, they are not typically widespread for all numbers. It's often a case-by-case basis, and understanding the specific reason for a failed call is key to determining how prevalent the issue might be. If you're experiencing a high rate of failed outbound calls, it's important to investigate the specific causes and address them accordingly.

Is there any way to bypass do-not-call lists for people that specifically opted in?

Nope.

Is there any way to get the twilio SID from those call IDs to help with their support? It is crucial that I at least understand why the calls would not go through for specific numbers

/call/{call_id}
you will get the Twilio SID
