is there a way to connect vapi with national countries for calling? even twilio doesnt offer this 😦

Yeah, you can set up a phone number to place and receive phone calls, either by creating one directly through Vapi or by importing your own from Twilio..

yeah i know, But im in Saudi arabia and i can't place calls or recieve one, either by twilio or vapi

Due to regulatory restrictions, Twilio does not offer voice enabled phone numbers in Saudi Arabia but I suggest you use nondomestic digits from other locales to make and receive calls..
