Info setting api voice of twilio

Good morning, I’m trying to understand whether to use your basic or superior service
I can in my customer registry and card, in the telephone number field.
apply a twilio api key to launch the phone call with a click?

and have an api installed on my tadabse app that when I get a phone call
to my virtual twilio number,
this customer who calls me and his number, bees
searches in my personal data table for that customer the number corresponds and opens the card for me
I still can’t find enough info to understand if this is possible, use tvilio api like voice not sms?
Other VoIP switchboard service companies offer me APIs to connect to my Tadabase CRM app, but I haven’t yet understood how to do it and what I can get.
Fine thanks
