How do I change the first ring option to the desk phone and have the cellphone/smartphone option as the rollover?

Schopke,

What you would have to do is select your deskphone as the first option in Call Handling & Forwarding, then add/select your cell phone as the second option and have the calls ring sequentially.

CAVEAT: If you select this way of doing it, your cell phone calls will go to your cellphone and NOT to the RingCentral Mobile application. You will lose the functionality of the RC Mobile app.

There currently is no configuration option to have the Desk phone ring first and then ring the Windows Desktop/Smartphone (RC Mobile app) as a second option.

Hello, is this still the case a year later? I NEED the desktop phone to ring first, and then if we are out of office, to forward to our mobile phone app. Thanks!

I am experiencing the same issue.  I can make it so that the Mobile App and Desktop Program ring the same time as my physical desktop phone, but I have found no way to make the mobile app ring second.  I followed the link that that Mary Rose posted and all that does is disable the mobile app from ringing all together.  Critical missing feature in my opinion.
