What is VoIP caller ID?

Voice over Internet Protocol (VoIP) allows you to change your caller ID containing your business name and phone number before you place an outgoing call. This helps you relate to the local area of the person you are calling.

These settings can be adjusted so no matter what number you or your agents are calling from, the displayed caller ID would be your company’s primary business phone number.

Customizable caller ID helps customers recognize who’s calling so they pick up the phone instead of rejecting the incoming call.

Benefits of VoIP caller ID?

Key terms related to caller ID

CID: Caller ID

VoIP: Voice over Internet Protocol

The ability to place calls over the internet instead of using your local telephone company. VoIP powers many internet phone services.

PSTN: Public Switched Telephone Network

The traditional phone network where phone calls are connected to other telephone providers. This is often an analog network, not a digital network.

CNAM: Caller Name Delivery

FCC: Federal Communications Commission

VoIP caller ID FAQs

What is the difference between caller ID and CNAM?

Technically these are two separate functions that have become synonymous. Caller ID is the process by which a caller’s phone number is identified and provided to you.
CNAM is the process by which a caller’s phone number is tied to the caller’s name which is provided to you. Over time “caller ID” just came to represent both.
Your VoIP service provider maintains this information and can update it whenever you want.

How do I activate caller ID?

There’s no activation required. The cloud phone system that manages your account is already configured to display caller ID information. And as part of the porting process we work with you to submit a request to add a caller ID Name to your phone number with a national CNAM.

Are there restrictions for caller ID?

Yes, the FCC can fine companies that spoof their outgoing phone calls with caller ID Numbers that mimic phone numbers that they don’t own. Spoofing is the unauthorized impersonation of another entity's phone number.
They may not manage the specifics of the caller ID Names, but the phone numbers are well within their purview.
Additionally, you can’t assign a CNAM to a toll-free phone number. This is true across business VoIP providers and landline phone systems.
The way toll-free calls are handled by the PSTN is different from non-toll free numbers. So no CNAM databases are checked when calls are placed using a toll-free phone number.
