The number poses as a number from RingCentral.com. Their tech support number is only 205 numbers different. RingCentral.com says someone is spoofing their block of numbers. The offender calls at all times of the day and night without leaving a message.

A call to the number gives message service is not available, sorry for the inconvenience.

Just got a call from this number. They asked for me by name but had a bad connection and don't think they could hear me. Then the call was dropped. I use ring central in my business from home. Glad I read the posting on here so next time they call, I will know it's not Ring Centra.

My Mother was called from this same number, she did not sign up for an account.  She was a target of identity theft.  I called the company and they refunded the charges to her AMEX, and flagged the account as fraudulant.

Was called by this 408 number, it rings once or twice, then stops.

I recently started using RingCentral.

Should you receive a call from 408-987-6352, you can ensure it's RingCentral by having the caller read your security question. Only RingCentral support reps would have this information. Spoofing caller ID is a growing concern, so please be sure you know your security question and answer associated with your RingCentral account. This will prevent anyone from fraudulently calling you and asking for your RingCentral account details.
