These days, we use pretty much everything but a landline to make phone calls.

A lot of us — around seven billion people — use mobile phones to do so. Another billion, you might be surprised to learn, make calls through VoIP services like Vonage and Skype (Google Hangouts’ user data is tough to pin down, but eight percent of Internet users aged 25-34 use the service’s VoIP component, so we can assume it too has millions of users). Then, last but not least, we utilize messaging apps like WhatsApp that have expanded to offer voice calls. That represents another billion (yes, a billion) users.

You get the point: Billions of people use mobile, Internet-connected, and app-based technologies, not landlines, to make phone calls. All told, 44 percent of American household are wireless-only.


Sounds high-tech, but it's not.


All of this sounds pretty high-tech. It must be expensive, right? Well, it isn’t. Wireless calling in all forms is one of the least expensive and most egalitarian technologies humans have ever invented. Thanks to widespread global development, cellular infrastructure and devices are cheaper to make and easier to deploy than ever before.

Wireless expansion on the scale we’re currently experiencing it is exciting but also challenging. We now need to port landline telephone technologies over to our new wireless devices.


Caller ID, something most landline users take for granted, stands out as a vital service that telecom providers have yet to deploy en masse on mobile. Today, most carriers can’t deliver reliable call data on mobile and international calls. Need caller data on a mobile call made from outside of the U.S.? Forget about it.


Caller ID coverage for mobile, toll free and international calls should be available to all businesses.


To us, that’s unacceptable. In today’s globalized world, we know that businesses don’t merely call each other from landlines. Instead, they use VoIP to call wireless numbers and vice versa. For a number of reasons, it’s critical for small businesses to have reliable Caller ID for any type of incoming call — landline, mobile, VoIP, or app-based. Accurate Caller ID informs an enterprise’s strategies, weeds out thousands of pesky spam calls, and is able to filter into CRM systems, where it can be logged and used to facilitate sales down the line.


Offerring access to 229 countries, OpenCNAM Plus is the Caller ID API designed for our mobile, globalized world. While traditional Caller ID services aren’t able to retrieve any caller information on calls originating outside of the U.S., OpenCNAM Plus produces accurate Caller ID on 57 percent of phone numbers outside the North American dialing plan. It doesn’t stop there. When an incoming mobile or VoIP call doesn’t provide caller information, OpenCNAM Plus queries non-telecom sources to procure reliable call data.


The explosion of VoIP and wireless technologies have made developing advanced Caller ID a priority, especially for enterprise. OpenCNAM Plus fights the spammers and unmasks unknown calls so your business can concentrate on doing what it does best: serving your customers.
