Frequently Asked Questions
What is a business VoIP caller ID?
A business VoIP caller ID, or CNAM, is the business name (up to 15 characters) displayed when your company calls customers using a virtual phone number.
CNAM is enabled by default on most landline phones. Most U.S. mobile carriers offer CNAM as an opt-in feature. This means your business name will appear on a mobile device only if the recipient has CNAM enabled with their carrier.
How does VoIP Caller ID work?
When you make a call through your provider, the system sends your number along with your CNAM record (the custom caller ID name). The receiving network then displays this information on the customer’s phone. With VoIP caller ID, businesses can go beyond just numbers and show a clear, branded identity.
Is business caller ID different from personal caller ID?
Yes. Business caller ID is designed to display your verified company name across networks, while personal caller ID typically only shows a number or a saved contact name. With VoIP CNAM, businesses can ensure their official name appears reliably, giving them more control over brand presentation.
How does caller ID (CNAM) differ from branded caller ID?
Caller ID (CNAM) is limited to a basic text name (up to 15 characters) and also built primarily for landlines but also can be displayed on mobile devices with CNAM enabled. Branded Caller ID, on the other hand, gives businesses direct control over their display on customers’ mobile screens, including verified brand name, logo, and call purpose, ensuring consistent, accurate, and trustworthy branding across supported devices.
Can I use my phone number for custom caller ID?
Yes. You can assign custom caller ID to your existing phone number, so it displays your business name instead of just digits.
Why should businesses get a VoIP caller ID?
A VoIP caller ID increases answer rates, improves brand recognition, and helps protect customers from spam or scam confusion. For small businesses and startups, having a business caller ID makes your company look professional and trustworthy while avoiding missed opportunities.
Can I customize caller ID?
Absolutely. With phone systems like DialLink, you can easily customize caller ID to show your company name instead of just digits.
What is CNAM?
CNAM, short for Caller Name, is the service that shows the caller’s name alongside their phone number on landlines and mobile devices with CNAM enabled. For businesses, CNAM makes it possible to display a business caller ID rather than just digits, ensuring your calls are instantly recognizable. For example, a dental office call might appear as “Bright Smile Dental” instead of an unknown number.
