 I don't know any telco or national law that would allow setting arbitrary numbers. You might<br>
have been assigned a certain number rage, and you could pick any from that range. If you set a<br>
number that does not belong to your range, the telco will typically substitute it with a<br>
standard number. Let's say you've got 100 numbers, e.g. 1234-0 to 1234-99, then anything out of<br>
that range, e.g. 77777777, is likely to show up as 1234-0 on the callee's phone.<br>
<br>
Having said that you also need to coordinate your efforts with your telco. You need to check<br>
several transmitting and switching facilities, like CLIP, CLIR, COLP, COLR, possibly CNIP. CLIP<br>
and COLP comes with different flavors. I'd say that the details are outside of what can be<br>
handled here.<br>

Legally many countries have mandated that you can not spoof or assign an incorrect CLID. </div><div><br></div><div>On the other hand, I have run into several carriers that will block calls that are not from the assigned block of DIDs. So using JG's example  if you send anything but one of the assigned numbers from the range of 1234-0 to 1234-99 they will block the call. This can be because it is the wrong length, format, or not in your assigned range. </div><div><br></div><div>Eric</div></div>
