I'm having issues trying to call my transient assistant, as everytime I try and dial the number, it says that 'this phone number has been disconnected'. I'm certain I have typed the correct phone number, and when I do outbound calls it does work, however, when I try to call the phone number (that is not assigned to an assistant, but instead the make.com webhook is connected to the vapi server), how can I fix this pleasse? Let me know if you need extra information.

for 1. I'm currently inside of twillio, and my phone number is active, however, do I need to change the voice configuration to the webhook url?

@Ali M Yes, that's correct. In order to connect your Twilio phone number to the VAPI server via make.com, you need to configure the voice settings in your Twilio console to point to the webhook URL provided by make.com. Here's what you need to do: 1. Log in to your Twilio account and go to the 'Phone Numbers' section. 2. Click on the phone number you want to configure. 3. Scroll down to the 'Voice & Fax' settings. 4. In the 'A CALL COMES IN' section, select 'Webhook' from the dropdown menu. 5. Enter the webhook URL provided by make.com into the field. 6. Make sure to select the appropriate HTTP method (usually POST) that your webhook is expecting. 7. Save your changes. After you've made these changes, try calling the number again to see if it connects to your VAPI server as expected. If you continue to have issues, please let me know, and we can explore further troubleshooting steps.

it says' accepted, through service difficulties, we are unable to connect your call at this time, please call again later' @Vapi

@Ali M It seems like there might be a temporary issue with the service or the configuration. Here are a few steps you can take to troubleshoot the problem: 1. **Check Twilio Status**: Visit the Twilio Status page to ensure there are no ongoing incidents that might be affecting your service. 2. **Review Webhook Configuration**: Double-check the webhook URL in the Twilio console to ensure it's correct and that the endpoint is operational. Make sure that the make.com scenario is active and properly configured to handle incoming calls. 3. **Inspect Twilio Logs**: Go to the 'Monitor' section in your Twilio console and check the logs for any errors or warnings that could provide more insight into the issue. 4. **Test Webhook Endpoint**: You can test the webhook endpoint directly by sending a simulated request to it (using a tool like Postman or curl) to ensure that the VAPI server is responding as expected. 5. **Contact Support**: If the issue persists, it may be necessary to reach out to Twilio support for assistance. They can provide more detailed information about the service difficulties and help resolve the issue. If you've gone through these steps and the problem is still not resolved, please let me know, and we can look into other potential solutions.

Here is the code that I used to test my inbound voice agent through postman, first, here is the html url [https://api.vapi.ai/assistant/20cb6181-d94c-43ec-a0ca-8e5ec79abab8] And this is the code that i sent a GET request for and it worked fine send in the txt file @Vapi Incident https://cdn.discordapp.com/attachments/1308000286538993684/1308006430871388181/message.txt?ex=673c5f6a&is=673b0dea&hm=4331102bded93e0eba2388cc0858012157be87b7a65a663e60d4189baaf0f6eb&

@Ali M It's great to hear that the GET request worked fine when you tested your inbound voice agent through Postman. However, it's important to note that Twilio typically expects a POST request to your webhook URL when a call comes in. If you've only tested with a GET request, you might want to ensure that your webhook is also correctly handling POST requests. Here's what you can do next: 1. **Test with POST Request**: Use Postman to send a POST request to the webhook URL with the expected parameters that Twilio would send. This will help you verify that your VAPI server can handle POST requests correctly. 2. **Check Twilio Configuration**: Ensure that in your Twilio number's voice configuration, you have selected 'Webhook' and set it to use the POST method to match the expected behavior of your VAPI server. 3. **Review the Code**: If you have access to the code that handles the webhook on the VAPI server, review it to ensure that it's set up to respond to POST requests with the appropriate TwiML or JSON response that Twilio expects. If you're still encountering issues after these steps, please provide any error messages or logs that you're seeing, and I'll do my best to assist you further. If you need to share a text file or code, please ensure that the content is pasted directly into the message so I can review it.

ive done the post request using the following url [https://api.vapi.ai/assistant] and then here are my voice agent parameters, i got a 201 status [] https://cdn.discordapp.com/attachments/1308000286538993684/1308007122243686410/message.txt?ex=673c600f&is=673b0e8f&hm=ba6fafd282e41a39311f626117586b9d84a678135a112d4bad11983e5bcc049d&

@Ali M It's good to hear that you received a 201 status code, which typically indicates that a resource has been successfully created or a request has been successfully processed. However, since you mentioned that you're still experiencing issues when trying to call your transient assistant, we should ensure that the entire flow is set up correctly. To proceed, please confirm the following: 1. The POST request you made to

https://api.vapi.ai/assistant

included the necessary parameters such as

To

,

From

, and any other required data in the body of the request. 2. The webhook URL configured in your Twilio number's voice settings is pointing to

https://api.vapi.ai/assistant

. 3. The webhook URL is set to use the POST method in the Twilio number's voice settings. 4. The response from your POST request to the VAPI server is in the correct format that Twilio expects (usually TwiML for voice responses). If all the above are confirmed and correctly set up, but you're still facing the same issue when making a call, it might be time to look at the detailed logs from Twilio and VAPI to identify where the call is failing. If you're unable to resolve the issue with the information provided, it might be necessary to contact support for more in-depth assistance. Please let me know if there's anything else I can do to help!

oh wait, is the webhook url in my twilio voice configuration meant to be configured to the vapi https? not the make.com one? @Vapi

@Ali M Yes, that's correct. The webhook URL in your Twilio voice configuration should be set to the endpoint that will handle the incoming calls for your voice agent. If you are using VAPI to create and manage your voice agent, then the webhook URL should point to the VAPI server's endpoint that is designed to receive and process Twilio's webhook requests. Here's what you need to do: 1. Set the webhook URL in the Twilio console's voice configuration to the VAPI server's HTTPS endpoint that is meant for handling incoming calls. 2. Ensure that the endpoint is configured to accept POST requests, as Twilio will send data to this endpoint using the POST method when a call is received. 3. If you are using make.com to trigger certain actions based on the call, you would typically set up the VAPI server to interact with make.com, rather than setting the Twilio webhook URL directly to make.com. By pointing Twilio to the correct VAPI HTTPS endpoint, you ensure that Twilio can communicate with your voice agent, and your VAPI server can then handle the logic for the call, including any interactions with make.com if necessary. Please update your Twilio voice configuration with the correct VAPI webhook URL and test the call again. If you encounter any further issues, feel free to reach out for more assistance.

does my vapi HTTPS endpoint need to include the assistant id pathing as well? @Vapi

@Ali M Yes, when configuring the webhook URL in your Twilio voice settings, you should include the full endpoint that points to your specific VAPI assistant. This typically includes the assistant ID in the path, which uniquely identifies your voice agent within the VAPI system. For example, if your assistant ID is

20cb6181-d94c-43ec-a0ca-8e5ec79abab8

, the webhook URL you set in Twilio might look something like this:

https://api.vapi.ai/assistant/20cb6181-d94c-43ec-a0ca-8e5ec79abab8

This URL ensures that Twilio sends incoming call requests directly to your specific assistant, allowing VAPI to process the call accordingly. Make sure to configure this URL in the Twilio console under the 'A CALL COMES IN' setting for your phone number, and select the POST method. After updating this setting, your Twilio number should correctly forward incoming calls to your VAPI assistant. If you have any further questions or need additional assistance, please let me know!

@Vapi wouldn't i want to make it a GET request, since its retrieving the vapi assistant?

@Ali M In the context of webhooks for handling phone calls, the HTTP method (GET or POST) is not about retrieving data in the traditional sense, but rather about how the data is sent to the webhook endpoint. For Twilio webhooks, it is common to use POST requests because they can carry more data and are more secure than GET requests. When Twilio receives a call to your number, it needs to send information about the call to your webhook endpoint. This information typically includes details about the caller, the called number, and other call-specific data. The VAPI assistant endpoint is designed to handle incoming call data and decide how to respond to the call, which may involve executing certain actions or providing a voice response. Therefore, even though it might seem like you are "retrieving" the assistant, what you are actually doing is sending data to the assistant's endpoint so that it can process the call. So, in your Twilio voice configuration, you should set the webhook to use the POST method. This way, when a call comes in, Twilio will POST the call data to your VAPI assistant's endpoint, and your assistant will then handle the call as configured. If you have any further questions or need more clarification, feel free to ask!

It still doesn't work using this setup, here is a screenshot of my voiec configuration @Vapi https://cdn.discordapp.com/attachments/1308000286538993684/1308008994933313556/image.png?ex=673c61ce&is=673b104e&hm=308f8bfa2b7d4e1c05df0d84e0b929613e16d279cd13f51564f132d0f24eb8f9&

@Ali M I'm sorry to hear that you're still experiencing issues. Unfortunately, as a text-based support bot, I'm unable to view screenshots or images. However, I can guide you through what to check to ensure your voice configuration is set up correctly. Please verify the following in your Twilio voice configuration: 1. **Webhook URL**: Confirm that the webhook URL is exactly as provided by VAPI, including the assistant ID. It should look something like

https://api.vapi.ai/assistant/your-assistant-id

. 2. **HTTP Method**: Make sure that the HTTP method next to the webhook URL is set to POST. 3. **SSL Certificate**: Ensure that the SSL certificate of the VAPI endpoint is valid. Twilio will reject webhooks to URLs with invalid certificates. 4. **Twilio Logs**: Check the Twilio logs for any errors when Twilio attempts to send the webhook. This can provide clues as to what might be going wrong. 5. **VAPI Configuration**: Make sure that your VAPI assistant is configured to handle incoming calls and that there are no errors in the configuration. If you've double-checked these items and the issue persists, it may be best to reach out to Twilio's support or VAPI's support for further assistance. They can provide more detailed troubleshooting steps and help identify the cause of the problem. If you need further guidance or have other questions, please let me know!

how do I check the SSL certificate

@Ali M To check the SSL certificate of your VAPI endpoint, you can use various online tools or your web browser. Here's how you can do it using your web browser: 1. Open your web browser and go to the VAPI endpoint URL (e.g.,

https://api.vapi.ai/assistant/your-assistant-id

). 2. Click on the padlock icon next to the URL in the address bar. This should open a small information window or panel. 3. Look for details about the security or certificate. There should be an option to view the certificate. 4. Check the certificate details, such as the issuer, the valid from/to dates, and any other relevant information to ensure it's valid. If the certificate is invalid, expired, or has other issues, this could be why Twilio is unable to connect to your VAPI endpoint. Alternatively, you can use an online SSL checker tool by simply entering the URL of your VAPI endpoint, and the tool will analyze the SSL certificate for any problems. If you find that there is an issue with the SSL certificate, you will need to contact VAPI support or your SSL certificate provider to resolve the issue. If the SSL certificate is valid and you're still having issues, please reach out to Twilio or VAPI support for further assistance.

this endpoint is fully certified @Vapi

@Ali M Great! If the SSL certificate for your VAPI endpoint is valid and fully certified, that's one less potential issue to worry about. Since the SSL certificate is not the problem, let's review the other potential issues: 1. **Twilio Webhook Configuration**: Double-check that the webhook URL in your Twilio voice configuration is correct and that the HTTP method is set to POST. 2. **Twilio Logs**: Review the logs in your Twilio console to see if there are any errors when Twilio attempts to send the webhook to your VAPI endpoint. 3. **VAPI Configuration**: Ensure that your VAPI assistant is correctly set up to handle incoming calls and that there are no configuration errors. 4. **Network Issues**: Sometimes, network issues can prevent Twilio from reaching your VAPI endpoint. Make sure there are no firewalls or network configurations blocking the requests. 5. **Contact Support**: If you've checked all of the above and the issue persists, it may be necessary to contact Twilio support for more detailed troubleshooting. They can help you understand why the webhook is not working as expected. If you need further assistance or have additional questions, please let me know, and I'll do my best to help you resolve this issue.
