Has issues – T-Mobile IP Relay Review

Whenever I get a call and I select accept call, nothing happens. Also, there’s no way to know someone is calling because it does not vibrate or make a sound to notify you that someone is calling. I’m deaf, but I do not have my eyes on my phone 24/7. Please fix errors with regards to accepting calls and nothing happens and add some kind of notification that vibrates or makes sounds.
