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.

I changed internet providers to T-MOBILE and was sent a 5G Gateway router. I read that there were issues because it has to be configured to Voiply.On two occasions I could not receive or call out with Voiply and had to use my cell phone. I contacted customer service and they fixed the issue and told me what to do if it happens again on my end and if that doesn't work call customer support. They were easy to work with for someone that's a senior and not computer savvy.

Voiply people and even their BOT have been very helpful. I've had the phone equipment since March 2025 but I hadn't tried to set it up until tonight. I had to wait to get a call back, but once the call came through, a wonderful agent named Blest helped me understand how to complete the process. Thank you!

I signed up for Voiply's Park Your Number service, as I no longer needed a home landline and found myself inundated with spam calls that were constantly disrupting me when I was working from home. I really wanted to keep my phone number as it I have had it for decades and there is no way I could remember all of the places that I have listed it as my main contact number, so this was a great solution to not severe that history but still provide me a break from these incessant solicitation calls... Now I am able to get email notifications when people leave messages so I can easily review them when it is convenient for me. I can also log in to my Voiply account and review a full log of calls, see which ones left or didn't leave messages. It is a joy to see the tally of calls (most of which were of no interest to me!) and to appreciate the amount of disruptions that have now been avoided. That alone is worth the very small price for the service. I only wish I had found out about this sooner. Bravo Voiply, bravo!

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 recently became a voiply customer. The initial set up was simple. However I had a hard time receiving calls. I call the help desk. The first tech had some problems, but put in a help ticket. I received an email from the second tech. They had no problem fixing my issue. The phone now works as it should.

I am happy to have found Voiply to park my phone number for a very low cost. I had lots of questions and made changes to my services several times. Throughout this, I had multiple interactions with customer service. The online chat bot was unable to answer all of my questions, but the humans I chatted with immediately understood and addressed my questions and then quickly processed my requests. Great customer service, especially for the price.
