I work from home and use my cell phone/RC app for the majority of my calls. Aside from seeing my office number, there is not a distinction of personal/work calls.
I like seeing the persons number so I can search the account as I am receiving the phone call to help with customer service and the person feeling like we care. If I use the only tool on the app currently for call forwarding, I cannot personalize their experience as easily.
If the incoming calls through the app could show "Ring Central Call" with the persons number listed it would be exponentially helpful.
