You can set your CLI to whatever number is within your number range. Several providers "allow" you to set it to whatever you like, but they generally have an agreement (that you sign up to) that says you'll only set it to numbers you own (or are within a number range allocated to you). Just because you can set your number to something, doesn't mean you're allowed to. This became very apparent when telcos used trombing to get cheap UK termination but you had to set your origination number to your real number, and then the trombing operator would be charged the UK termination rate, not the blended rate (which is an ITU regulation).
