I can find the phone # of anyone who calls me, even if the caller ID says restricted. There are people who know how or know someone who knows
As opethPA is stating above, its not the same for a large call center as it is for your home phone. I am not completely savvy in how PBX systems work,
but when I was in IT one of the guys in my group used to maintain ours at a large call center.
In a call center, you might have thousands of lines going into the the building then into a computer switched PBX system. This is how the system
auto-dials you, its how they connect your account information to the call as the agent receives it, etc... They are not issued thousands of phone
numbers that correspond with those lines though. As the company only wants one incoming phone number, and not a thousand of them, calls come into the
PBX system from one number, and are routed from inside it.
The same applies to outgoing calls, the PBX will assign a number to show on caller ID, or maybe they won't assign one. That is why when you get a
call from a business, it could show up with the main company number/name (eg "Home depot 1800-555-5555"), or “Unknown”, “Restricted”, or
even a “Spoofed” caller ID name/number (eg. "NonYa! 000-000-0000"). It all depends on what the company has the PBX system set to transmit.
most phone #'s that say resticted on caller id are inside the phone or caller id equipment.
For example police officers may request “restricted” home phone numbers that are untraceable for personal/family protection. Restricted from a big
company is most likely from a PBX system as mentioned above. Restricted, unknown, or spoofed numbers can be sent through Voice over Data systems such
as online phones. About the only one you can trace back is when someone dials *67, which can be *69'd back to the source.
