In order to find the required keys on Twilio please follow these steps:
1-Twilio Account SID:
2-TwiML APP SID:
Create a new TwiML App.
Give the app a name and paste the webhook URL(https://crons.vbout.com/Twilio/Voice).
After saving changes the TwiML APP SID will show.
3-API Key/SID & API Secret
Search for API keys and create a new API key.
Make sure to save the API Secret in a safe place in order to use it later.
One last step before switching back to VBOUT is to assign the TwiML APP to the active phone number.
