Someone at this number continues to call my cell phone every few days but never leaves a message.

Received a call to my cell phone but no message.  No idea who this is.

This number calls our phone lines and refuses to leave a message and hangs-up rather rudely when asked.

I got the same as above...number called did not leave a message.  I tried calling the number, but got a busy signal

Calls my cell daily, but doesn't leave a message.  Computer dialing to sell me something, I guess.  Maybe next time I'll answer it out of curiosity.

It's CPE Solutions for CPA CPE.

Got a call today from this #, which I don't recognize. I didn't answer and no message was left.

Someone called while I was on the phone. No message was left.
