I have integrated the incoming and outgoing call by using twilio java script sdk and also implemented the outgoing call transfer. I have checked the Twilio API response. It creates the iterations. For example, I have logged in with ‘rohit’ (number assigned to Rohit +158********) on web browser (I’m using the token and identity for making and receiving the call). I retrieve employee details and initiate a call to the customer number “+9179********”. Twilio acts as a middleman between the caller and receiver, creating a dynamic connection between Rohit (+158********) and the customer number (+9179********). The call is now ringing on “+9179********”, and once the receiver picks up, the call status is ongoing.
