LOCAL NUMBERS

Why Does Area Code Matter?

A local phone number provides several significant benefits to a small business. Firstly, it enhances the company's presence in the local community and makes it appear more accessible to customers.

This local presence further establishes trust and credibility, as customers generally feel more comfortable dealing with businesses they perceive as local. From a practical standpoint, a local number is also more convenient and often cheaper for customers to call compared to long-distance or toll-free numbers.

Additionally, a local number serves as an effective marketing tool, reinforcing the association of your business with the local community. Lastly, having a separate business number helps maintain the privacy of your personal number, creating a clear boundary between professional and personal communications.

How to Spot a Spam Call or Text

Beware of unknown senders, urgent action requests, and too-good-to-be-true offers. Check for spelling errors and unfamiliar URLs. When in doubt, don't click or reply. Always verify from official sources.

Check for unknown numbers

Check for Unknown, Unfamiliar Numbers

A common sign of a spam call or text message is that it comes from an unknown or unfamiliar number.

Sometimes, these numbers may even appear to be from another country. If you don't recognize the number, be cautious.

Don't answer calls or reply to texts from numbers you don't know, especially if they aren't leaving messages.

Beware of too good offers

Beware of Too Good To Be True Offers

Spam messages often contain offers that seem too good to be true.

These could be promises of free vacations, big discounts, or large monetary rewards. As a rule of thumb, if something seems too good to be true, it probably is.

Always verify such offers from a reliable source before responding.

Look out for personal information requests

Look Out for Urgent Requests for Personal Information

Spam callers or texters often try to create a sense of urgency to get you to provide personal information.

They might pretend to be from your bank or a government agency, claiming there's a problem with your account or that you owe money. Never provide personal information in response to an unsolicited call or text message. When in doubt, hang up and contact the entity directly using a number you trust.

What Real People Say About Us?

Experience why Voiply has become the top-rated home phone provider, trusted by over 50,000 satisfied customers.

For some reason I had lost the device registration" of my home Voiply phone system. I contacted their customer care service number and was connected to their AI support. It worked amazingly well, and the AI bot, whose name was Jack, answered every question I asked it as if I talking to a real person. After making sure all the interconnections where properly connected and working, it tried several times re-register my device. It was unsuccessful and realized that I needed a real "customer care technician" to help correct the problem.

If you’re a freelancer or solopreneur looking for a reliable phone system, Voiply is definitely worth checking out. The call quality is super clear, even on their starter plan—which also includes built-in CNAM (a nice bonus you usually pay extra for elsewhere). Right now, they’re offering 50% off, which makes it a no-brainer if you’re just getting set up or want to upgrade your setup without breaking the bank. What really impressed me, though, was their support team. They're available 24/7, quick to respond, and they actually know what they’re doing. That kind of service is rare. Also, their KYC (Know Your Customer) process adds a layer of professionalism that shows they take security and compliance seriously—great if you’re working with sensitive client info. Overall, Voiply just gets what solo professionals need: clarity, support, and a system that works. Big fan.

We used Voiply service for many years with trouble free service. When it came time to cancel our service (just don’t use the land line anymore) they made this very simple to do. If we ever need a landline again we will definitely be back!

I've tried a few phone apps over the years. Voiply tops them all with ease of use, excellent phone app and the dashboard is well laid out to find what you need easily. To top it off, the support is AMAZING! They are very prompt and handle all inquiries quickly. Even the AI chat bot is smarter than most I've used. Highly recommend their services!

I've been a Voiply customer for almost three years now. During this time, I've only had three outages due to loss of electricity or other unknown issues. Each outage, I've contacted customer support and every problem was promptly and quickly addressed by their responsive and professional team. I highly recommend Voiply for VOIP telephone service.

Voiply is great. Probably the best telephone VoIP service in the business. All phones are being forced to go Voice over IP. We were with Windstream/ Kinetic/ and whatever company they just merged with. Voiply’s cost and superior customer service kicks the mess out of our previous carrier. Check out the cost and you might just be their next customer.

I love the ease of purchase, the online dashboard is transparent about services and features, the customer service has always been topnotch, and you can't beat the price! I have the landline phone for my kids too young for cell phones and it's an added safety feature should I need to call 911 as the number is tied to my physical address. Worth every penny!
