I was experiencing some strange call behavior. Calls to my main extension were going to other phone numbers which I had used in the past. Turns out that ALL of my old forwarding numbers, which were toggled off in Call Handling, had been toggled back on. Calls to my RC extension where ringing all ten of the numbers in my ring group. I still use those other forwarding rules from time to time but I had NOT toggled them on. This was something which RingCentral did. In talking with another company which uses RC, they experienced the SAME problem within the past few weeks where all numbers in their ring group were inexplicably toggled on.
