Hi! I created a free Vapi phone number, set it to an assistant, and placed ~40 successful test calls to it yesterday. As of last night, calling the number returns either a ‘call cannot be completed as dialed from my carrier, or simply returns silence until timeout. Since last night, any US Vapi phone numbers I create are not working when called. Curious what I’m missing. Hoping to stand up a demo of this assistant w a phone number. Thanks!

Hi there! 👋 I understand you're experiencing issues with your Vapi phone numbers not receiving inbound calls after previously working well. I can't pinpoint the exact cause of your specific issue without seeing your account details, but I can definitely help with some troubleshooting steps and information about recent issues that might be affecting your numbers. Based on the information I found, there have been some recent issues reported with US Vapi phone numbers. Several users have reported problems with call completion and connectivity, with some mentioning that "the same thing is happening for US numbers as well now" and others noting a "major issue with vapi right now" including "SIP Trunking Failed" errors and calls that can't be completed. Here are some troubleshooting steps you can try: 1. **Check activation time**: It takes a couple of minutes for a newly created phone number to be fully activated. During this period, calls will not be functional. However, since you mentioned your number was working yesterday, this is likely not the issue. 2. **Verify assistant association**: Ensure that an assistant is still properly associated with your phone number. According to the [documentation on phone calling](https://docs.vapi.ai/phone-calling), you need to provide an

to a phone number for it to handle inbound calls. 3. **Check for network issues**: Verify that there are no network delays that could be causing the call to drop before the Vapi assistant picks up. 4. **Review recent configuration changes**: If you made any changes to your setup since the successful calls, review those changes. 5. **Check for international call restrictions**: If you're testing from an international number, verify that your Vapi number is set up to receive international calls and that there are no restrictions in your Vapi dashboard.

Hey Dessin d'Arche, could you share all the failing call IDs so I could take a look at what could have been going wrong here?
