For record keeping and billing purposes, I'd like to go by the callers telephone number. <br><br>This method works fine as long as the caller doesn't have callerid blocked, but what are my options if they do block their number? I know there must be a way to report it, because there is a service provider here in my area that if I call and block my number, they are still able to obtain it. I know that when dialing a toll-free number, that the number is reported regardless. But what about regular non-toll free numbers?<br><br>Does anybody have any ideas how I can do this? Are there any providers out there that offer this service over PRI or some other method?<br><br>Thank you in
advance.<br><br><br></div></div><br>
