have received a few calls from this number -- on both my phone lines. i am on the do not call list, so they are dialing all numbers in the exchange it seems. they claim to be sbc messaging (am not an sbc customer) -- i redailed the # to hear it and they are selling something but i did not listen to the message long enough to know what. it's all computerized/automated -- no live person.
Every time I've received the call, probably about 11 times now, the recorded voice states; "Due to a technical problem on our side we are unable to speak with you directly" They then just disconnect. I called the number and got only a message. They say they are exempt from the do not call list. They are selling tickets for a charity. They ask you to state your telephone on the answering machine to be removed. I would guess it is safe to leave number, since they already have it.
Have received several nuisance calls from this number, at varying times of the day. Always "Due to a technical problem on our side we are unable to speak with you directly". It's like why are you calling them. Says it's "SBC Messaging."
