Ok, so. Most of the time when you call from a business (hotel), a main number will appear on the caller id.
The idiots that use these Escort Services think that they are paying for discretion.
As best as I understand, that number appeared on the DC Madam's caller ID. Now I'm not sure why the blog is claiming that's Bill Clinton's number when its clearly the main number of the Park Hyatt hotel. Could Bill Clinton have been the guest at the Park Hyatt?
I suppose it's always possible, but I'm not sure how anybody would know that from the information presented.
