Troubleshooting

Are you not receiving the call at all?

The first thing to check is that your SIP Service Provider configuration is correct. Next, double-check the username, password, and host. If your Provider has an Admin console, check if you can see the registration coming from Fonoster.

Next, make sure the from matches the Number given to you by your Provider and ensure the to has the correct prefix (for example, +1, etc.).

You receive the call but immediately hang up (did not hear a sound)

First, verify that Ngrok is still running. Next, compare Ngrok's URL with the webhook on your Number. They must match!

Then observe the console's output where your Programmable Voice Application is running, and look for any errors.
