Why You Need Call 48 Origination USA Footprint

A VoIP footprint refers to the ability to supply VoIP services and solutions to a geographical area. If you can only offer services to Florida, it means your footprint is Florida. Call 48 has made it our mission to offer one of the largest North American origination footprints available. So much so, the 48 is in our name.

As a premier CPAAS provider Call 48 continues to expand its VoIP footprint throughout North America, blanketing the United States and Canada, as well as across the globe. With the ever expanding of its service area, Call 48 is able to deliver in-demand, flexible and innovative phone and VoIP-based services to more than ever before.

Call 48 is a carrier serving the business marketplace with high-quality and innovative services at industry low prices, Call 48 meets the demand of resellers eager to market flexible and affordable VoIP-based options.

Every time we expand our footprint it means our customers can move into new territories with their telecom ventures. If you need a new DID phone number in the United States, we make it as simple as go to our innovative, CPaaS customer platform VoIP Portal, and click on a DID.

Our Origination Footprint is Bigger and Size Matters

Is your provider’s footprint just not big enough?

If you are a wholesale, private label or reseller customer looking for a phone number, look no further than Call 48. A VoIP carrier footprint by definition means the area where Call 48 has access to sell our own DID phone numbers. We have taken the time and spent the money and resources to offer complete coverage of the United States from over 13,000 rate centers, more than 180 LATAs, plus nearly 120 other countries.

This means your provider doesn’t own or have enough access to sell different phone numbers from around the country. And when this happens, they have to source the phone numbers you have requested and need from other providers and resell them. Many will not do this because it takes time, which is a waste to them and it isn’t affordable, so they won’t spend the money.

Call 48 has taken the time and spent the money so you don’t have to.

Call 48 is a premier CPAAS provider offering the United States as our On-Net footprint. On-Net means we have done the expensive and heavy-lifting work for you. This is our infrastructure and our phone numbers.

With Call 48, you gain access from rate centers where we are registered with NPAC (the Number Portability Administration Center) and where we have infrastructure and tandem circuitry to receive calls in and out of those networks. Not only has Call 48 incurred the costs to do this, we also have multiple regulatory filings and approvals as well as state filings. 

Who benefits from a complete VoIP footprint?

If you do telecom business beyond a generalized, geographical area, you need a VoIP company like Call 48 which provides a complete VoIP footprint. If you only need numbers in the Chicago area, then you only need Chicago phone numbers. As soon as you need them outside, you are going to need to increase that footprint.  

At Call 48 we strive to ensure the size of our VoIP footprint are continue to expand it. It is our goal to never have a customer not have access to the phone numbers that they need. Contact us today to find out if we have yours waiting for you.
