I have received NUMEROUS calls today from area code 903 followed by 910... the nos were 903-910-1510, 903-910-1537, 903-910-1205, and quite a few more... and all were within 15 minutes of one another.. When I answer, theres no one there.  When I call back, it just beeps.... starting to really hack me off.  I am on no call lists, but of course, no one really follows that rule now do they??
