that article lacks a lot of information...
as for the first line of the article - it implies that TELEMARKETERS can not spoof there telephone number.... no where in the article does it state that they have made it illegal to spoof CID - they may have, but this article does not say anything about it...
IF they are banning all use of CID spoofing then that is pretty stupid, so a company can no longer call you with the toll free number appearing on your CID, or there main number appearing on your CID - because to get the toll free number, or main line to appear on your CID they would need to spoof the number.....
there are many other legitimate reasons for spoofing caller ID, such as stalking and harassing people... umm... i mean for example i call my customers contact number when no one is home - the customers were constantly calling me back on my cell phone instead of calling the office to reschedule there appointment, so now i spoof the office phone number when calling customers from my cell...
