I want to implement a click to call functionality inside my website to anonymously connect freelancers with prospective customers.
Suppose freelancer-A clicks on his browser to call customer-A's phone. At the same time freelancer-B also calls customer-B. Do I need multiple twilio numbers as caller ids to do this or one twilio number will suffice?
Please note that the (freelancer-A and customer-A) call and (freelancer-B and customer-B) calls should be separate and this shouldn't be conference call between 4 parties.
