Calls business phone  every day the past week and more and doesn't say anything and hangs up.

These people call and want to talk to the person who handles the at7t account. They are not at&t, they are some sort of wholesalers. Annoying.

Must be a poor robo system. They have phoned several times and do not respond when answering. A return call yields a poor recording with the word communications in it.  After a brief hold, the gentleman  who answered was polite and asked if I was returning a call. He explained it was from Birch communications offering a way to lower our phone bills and that they would be calling again.

Asked to speak with the person in charge of the at&t account. I simply told them to call at&t, because if I was actually in charge of the phone account, I wouldn't be getting this spam call right now.

Telemarketer for long distance company. Would not talk when they called, so I called back on our business # phone line that does not receive calls. Very nice lady said she would remove the # from their system with no problem. We will see if this is true.  Said At&t Telemarketer and they are out of Houston, not San Antonio as the prefix suggest. FYI... Did not try to get me to switch when I called back either, just removed # and said have a nice day.  Ruined the fun I was going to have with what I thought was a scammer. Oh well, One thing I know is there will be others calling.

Two things are certain in life...
