Never left a message.  Received a call from a similar number yesterday (307) 212-6237 that was a recorded telemarketer.  Said "Don't hang up" at which point I did.

Same [***] calling us

Received a call on my work number. Did not answer and they did not leave a message.
Have starting receiving a number of like calls. They must have obtained my work number from somewhere. Really irates me since I do not give that out except for business purposes.
I'll turn it over to legal if it persists...
