Hi this may be already a post but I was really hoping that there would be some integration with a USB handset. Some folks don't always love a headset and furthermore a handset provides a speaker phone function which can be handy. In our business we love the ringcentral desktop app and would prefer using it than connecting IP phones but really the only way to use the desktop app is by using a headset. There are some devices out there like the Polycom cx300 or polycom cx200. I have purchased the polycom cx300 and the speaker and mic work with the app but other functions like dialing and hanging up the handset don't function and I'm hoping that someone could write a driver for them. Would be willing to pay!
