Nextiva Reviews in October 2026: User Ratings, Pros & Cons

Thanks to the amazing staff at Nextiva!

We’ve had one of the smoothest launches of all time! The transition from our old phone system to Nextiva’s VoIP was as easy as they said it would be. Just to be safe we made the move over a weekend to ensure the lowest impact. There were no outages and it was working smoothly for the staff the next week. A couple of training sessions and that was it. Very impressive service!

Nextiva’s SIP Trunking has helped us dramatically reduce our phone service costs. We added it to our existing PBX set up and were able to transition right then and there. I was surprised we didn’t have to get new hardware. It was a success! Our costs went down as expected!

implemented NextOS with Nextiva

I had heard a lot about Nextiva from a new colleague. They had implemented NextOS at his old work and seen a lot of great results from the tool. We proposed it to the board and they approved the project. We were surprised how easy it was to both get approval but then also to get the tool live and working in our ecosystem. Usually these are very long projects and despite the guarantees from Nextiva we were skeptical that it was going to be “so easy.” Despite our doubts we were live within a ...

We’re very happy with our Service.

We’re very happy with our Nextiva service. The switch over was a simple process and their customer service team made it smooth and quick (a nice surprise) usually these integrated software solutions are a nightmare to launch so we had low expectations. Everything, however, went great and we’re up and running. The team has been trained and is working the system into our overall process. It does a lot so it’s a step by step process to make sure you’re getting it working right for your ...

NextOS has all you need!

Our business is using NextOS and has been doing so for the past 6 months. We were one of the first businesses to get onboard as we could see the value and advantage to a system like this from the get-go. We didn’t want to get left behind and it actually saved us from updating 4-6 other systems in the business. It just made sense to go with NextOS. We have previously been on Salesforce but found that the implementation was so complicated and fraught with issues that the team weren’t really ...

Absolute worst customer service I've…

Absolute worst customer service I've ever experienced. Lost me as a customer.

NEVER USE NEXTIVA!

It is with much disappointment and regret that I write today regarding my recent experience with Nextiva and its employees. It was, without a doubt, one of the most personally frustrating and financially damaging experiences I have had to experience in my years of communications with a service provider of any kind. I am a business owner who depends greatly upon the ability and ease for my customers to contact me for products or services. Without the communication of both our established and ...
