This is not a service offered by one's phone company. It is a web company in the USA that provides the 'service'. Telemessage. How it works: a SMS text is sent to the landline number and the receiver's phone rings, then an autotron voice delivers the message. Both the sender and receiver are charged for the call. Your local phone company can not turn the 'service' off. From what I have read so far, you have to contact the website, supply your land line number and request it be blocked. No opt out option from utilities on this one. I got my first call today and fortunately I hung up as soon as I heard 'you have been sent a text'. If it had have gone to my phone messaging service, I would have been charged for the text. The phone company is going to make lots of money on this once the telemarketers gear up. Unfair and Nasty.
