How can I make VOIP Call from Website to Mobile Device?

Question

I need to make a VOIP call from my website to a mobile device. I tried using Twilio. But it seems it doesn't work in India. And the Twilio support is not giving appropriate response.

Can anyone suggest me a possible solution for this.

There are two end users here. One is the principal of a school, and the other one is a teacher. Principal is using a website, and teacher is using a mobile device. We need to give a platform to the principal to make a call to the teacher, through its browser. We are using PHP/Laravel as back end.

Answer 1

Twilio has a working sample on how to achieve this in Laravel.
