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.

AMAZING FEATURES

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, 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 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 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.

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!

I had a problem getting text messages and voicemails. As soon as I contacted them, they responded immediately and after a short period of time, everything was working.

We switched to Voiply after our current VOIP provider increased our rates 60% without warning (and we had been with them for over a decade). What a difference! They helped immediately with porting issues then fixed the mobile app so that we could get incoming calls. We were up and running within a day of the port completion. Our previous VOIP provider took days to fix an issue - Voiply fixed problems within minutes of our report. So customer support definitely gets five stars from us! The Voiply price is also more reasonable so that was very helpful. And both the web interface and mobile app were well written (I'm a software consultant/developer). I've added a picture of the Grandstream device that Voiply supplies for free. Besides power, it has inputs for a phone (RJ11) and an ethernet connection (RJ45). It is programmed to get a DHCP address on your internal network so be sure to allot some addressed on your firewall router for DHCP. We are glad that we ported to Voiply - what a difference from our previous supplier.

The human agent of the client service was super fast detecting a small hiccup on the answer given by the AI agent regarding my account. Without me asking or having time to do it the agent presented herself and offered immediately to review the situation... not even a couple minutes go by and I am receiving the information by email and on the live chat session. Incredible and nowadays surprisingly attentive client service. Well done.

After almost five years of trouble-free service, my Voiply connection failed. I visited the website and chatted with a robot, who instructed me to check all my wire connections. I thought, That's what they all tell you, and it never solves the problem." The robot connected me with a live agent who told me to check all my wire connections. She was more insistent than the robot and eventually determined that the connection to my modem was faulty. I connected the cable to a different port, and the system was restored. The moral of the story....Listen to your agent. She knows more than you do and is there to help you.

Customer service helped quite efficiently during sign up. When I receive the equipment and hook it up, I should know more. I know someone who has it and says it's great.

This was the easiest transition of a phone service ever! Everything transferred right on time, received the voiply box within days, plugged it in and done! No more monthly bill from a phone company. I wish I would have known about this service years ago.

Yes, we still have a landline telephone. Voiply has been an excellent provider for years. The system works smoothly, including voicemail. If I ever have a question they respond very quickly. I always feel that I am chatting with a real person, not some AI-generated bot. The price is very reasonable and I recommend them highly.
