Episode 1225 (1:04:28)

Benny from Phoenix, AZ
iPhone 6s

Benny just got hearing aids and he's trying to transfer his work calls to his iPhone so he can hear them through his hearing aids. Leo says that the Starkey App for the iPhone is great. But to route his business calls to the iPhone is a challenge. RingCentral has an app that can route it to his iPhone, but whether it works in concert with the Starkey app is another story.
