A very real sounding voice that is a recording says she is "having problems with her head set and can you hear me now" solicits a "yes' which allows them to go on with a recording leading to another "are you interested". Do not answer "yes" as if they record it, it can be used an an "ok" for a deal or further calls. Block it. Tho they constantly switch to new banks of phone numbers. Blocked on my cell but they also call my office where I have to pick up. A constant pain.
