This is an outbound only number for Interactive Brokers. I dialed it back after seeing that someone reported it as an Interactive Broker number. No one answered when I called it back, I got the recording that it was not a working number. They called me back and I answered the call. The caller was responding to an question I had raised with them. This was not a telemarketing call. Below in call type, there is not an option for "Reply To Inquiry" or "Legitimate Return Call". Might want to add one or both of those to allow someone to correct themselves.
