Hello,
I can able to solve your problem with my experience. basically, I am .Net developer, But I can solve your problem using Twilio Client Javascript library. I have work experience in Twilio Fax, Twilio Browser Callin and Twilio Task Routering. I can take 3-4 days to complete this work because I am already worked on other project and it is my second bid on freelancer.com, so I need some time to used to this system.
Thank you.
I hope you give me feedback as soon as possible.
