I've been using Ringcentral for several years now, and have never used or given out the toll free number assigned to me by Ringcentral. I get a minimum of 10 spam calls to this number per week, and each one is a 5-6 cent charge. Is there any way to block all inbound calls to the Ringcentral-assigned toll free number? I am just as happy to delete the number, if that's the only option available. Thanks for any help you can give!
