PPTAZ,
We do say on our website "Caller ID spoofing, and telemarketing calls are not allowed with our service" and by that we mean that telemarketers aren't allowed to use our system for those damn calls that bug your dinner that appear to come from your local area code.
If your the legitimate user of the callerID number passed to us, even if it's your work number we'll pass it for you no problem.
