We are having the same problem and we do not have any advanced call handling rules in place on any of our phones. Also our QoS shows green across the board and I went back a couple of weeks when this all started.
I just posted this same thing on another thread. Has anyone found a solution? We, too, have simultaneous ringing to multiple phones.
Is this still an issue with anyone? We receive these calls all day long where nobody is on the other line. We will sometimes wait several minutes to see if the call is being transferred to a call center or something, just to see if it's even a telemarketing call. However nobody ever comes to the line. We've even called several numbers back to find they are not legit numbers.
A while ago we had settings that were not correct and when we couldn't hear anyone on the other line, we would hang up and they would immediately call back. None of these callers call us back so we think it's not a setting.
They all have caller ID, most of the times it's a city/state with a phone number but oftentimes there is a name and a number.
I know of the tactic to determine if a number is legit in order to then give the number to telemarketers, but we don't end up getting many telemarketers, so it doesn't make sense.
We are going to try adding a layer where the caller has to press 1 to reach someone. Currently, the calls ring the whole office simultaneously without any layers in between.
I can't hear anything, inbound or outbound. So frustrating - can't use the app at all right now. All my other apps work fine! Zoom, Hangouts, Teams, but it is dead air on RingCentral. This has to work or the app has to go!
