Unable to open a browser when call is accepted

[smzapp]

I am triggering a call from postman to mobile phone using twilio. I am able to call successfully. It rings on my phone. When I click accept, a message is prompted on the call. When I press 1, it says something error and does not redirect or open a website link. How to fix this?
