91% of the customers that order from us the Voiply Adapter works out of the box no issues. Our reviews speak for themselves. 100% customer satisfaction is a difficult task to achieve, but we strive to take care of all our customers. The 9% of customers that don't work out of the box usually experience issues out of our control. The way new Internet providers communicate with the public internet over Carrier-Grade Network Address Translation (CGNAT). Essentially it's a technique used by internet service providers (ISPs) to conserve IPv4 addresses and facilitate the sharing of a single IP address among multiple customers. Causing VOIP traffic issues. Traditional providers like Comcast, Verizon, Time Warner all still communicate with a dynamic IP Address. These traditional providers still pose a problem with their routers. Not allow their customers to access the interface to make any changes, blocking VoIP traffic, or enabling SIP ALG without the ability to disable.

Our workaround includes an additional device that will give us the ability to setup a direct VPN connection to our servers. The device is call Opal, this device is available at our store for $40. What does this device do special? This device is considered a travel router, but our use is intended to route over your internet provider traffic over a VPN (Virtual Private Network). This allows us to control the Voiply adapter VoIP traffic right to our SIP Servers. Think of it like this: It's a secret tunnel that lets your Voiply adapter connect to the internet safely. Even if there are problems with T-Mobile or Starlink, or if your internet provider doesn't usually let you change settings on your router, our tunnel makes sure you can still get online easily and securely. Let's get to configuring the device.

What Real People Say About Us?

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

Dealing with Voiply was quite refreshing. Their customer service team, including AI, was fast and helpful. The equipment needed to use Voiply arrived the next day. After installing it, I sent a note saying that it had arrived and received a confirmation back promptly. My husband and I are impressed with Voiply and only wish that we had found them sooner!

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.

Hey guys, Voiply? Who, What Never heard of this company but I’m glad I ran across them. Saving me money on my telephone service. Sounds mickey mouse but far from it. Quality A+ Clarity A+ Ease to hook up A+ . If you’re getting your current number ported over, and after you connected the color coded wires, only 3 no big deal and you try to make a call and can’t don’t panic and think you made a mistake by switching don’t, it only takes a few days to get it running and what’s cool it rings also on your cell phone. Never have to wait at home for an important call. I’m excited with Volply and using my telephone bill savings to super size my next McDonald’s order with the extra money I’m saving. Roger D

All I can say is it was SEAMLESS! I had no idea this service even existed until my son shared it with me. I’ve had my number for 45 years and didn’t want to lose it but had to ask if it was cost effective. This made my answer easy…NO it wasn’t until I parked it with VOIPLY. Thank you for the service and for making the switch so easy.

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 the best phone service available. We changed to Voiply because of the length of time it took for our previous carrier to respond to us. Voiply, from the beginning, responded immediately, without delay to any request we made. Their representatives are so kind and understanding. I encourage all that read this to make the switch without delay

I recently signed up for Voiply and the setup and install was extremely easy and worked beautifully right out of the box. The calls are clear and sound very good. The Voiply web settings are also easy to navigate and there are lots of options to customize our phone settings.

We recently switched our business landline to Voiply and had some issues after the porting process was complete. I contacted customer service, and they were able to resolve the issue quickly and get us up and running. The additional features provided by Voiply over a traditional landline phone are wonderful.

I was tired of the high cost of my home phone with my internet provider so I found Voiply on line. Their crack team of agents seamlessly transferred my phone number and service to Voiply. I am now enjoying excellent phone service at one third the cost. The service staff is exceptional and expertly performing their support for customers like me.
