Office Manager

The ability to call customers from the app where my personal cell phone number will not show up.

Associate

Nextiva offers a diverse range of features including VoIP calling, video conferencing, team collaboration tools, and CRM integration.

Operator

Nextiva offers a wide range of communication services, including VoIP (Voice over Internet Protocol) phone systems, video conferencing, team collaboration tools, and more.

Co Owner

The only thing I have issues with sometimes is when I am texting a customer without saving their contact yet, when I save them as a contact it will remove all the previous chats and call log.

President

Literally 20+ emails to close my account and they still charged my credit.card the momth after i closed my account.

Landscaping maintanace

Another advantage of Nextiva is its robust notification section, which serves as an ideal archiving feature, unlike Dialpad which lacked this capability.

Sr. Financial Planning Consultant

Technical support walked me through using the desktop to make calls in contacts and created a list of associate cell phones I frequently need to call.

Administrative

Your user-friendly interface has made managing calls and messages effortless, boosting our productivity. While my experience has been positive, I believe simplifying certain features in the mobile app could enhance user experience.

owner

Get us to verifying pin, company name, and owners name you'll have to provide this a minimum of 3 times to speak to someone.

Administrator

The sales representative to the phone technician and customer service representatives has restored my hope that not all businesses are out to get your money while providing fractured customer service.

One thing they are good at is passing the buck to several people and never getting a concrete resolve in the issue of the SMS registration.

Marketing Manager

Call tracking and being able to fully pinpoint where the action happens is a must, and Nextiva needs to work more in this area.

CONTROLLER

I like being able to manage all of my employees phones from the portal.

Administrative Manager

I can download the Nextiva App on my cell and answer calls for the office from my cell at anytime anywhere.

The concept is great and being able to customize a phone service is exactly what a growing business needs.

Agent

I hate that we didn't have a direct connection since the issue was I could not receive forwarded / inbound calls at my desk due to some kind of internal widget

Founder-Principal

The 1 wishlist item I have is the ability to add additional licensing without having to reach out to Nextiva support.

i  love the transfer to email for missed calls, but love the faxes to emails so toner is not wasted printing junk emails

They sent me an email that unless I respond the case number will be closed.  

Admin

The crew behind the scenes is quite helpful, and the program itself is very straightforward to use. When there are problems that we are unable to resolve on our own, the support staff is typically ready in a matter of minutes to restore order.

underwriter

its been a while since we used them, but i believe getting access to our admin account and then having risks if an employee left/came back it was hard to access but thats not always a bad thing it just didnt fit our company at the time.

Operations Manager

We have had great service with Nextiva and when we have an issue, they offer several options to obtain tech support.   And we have been very satisfied with their service, tech support and equipment.  

Systems administrator

Call center controls are an addon from the unity platform which does not have the greatest of call center functions.

IT Manager

Sometimes support is difficult to connect to you have to wait a long time for a 2-minute solution.   But I know they are inundated with calls.   But it always happens when you need the help immediately.

Customer Service-Sales

The reporting, call clarity, and the call monitoring help us tremendously in our daily operations.

Owner

Price,call quality,the ability to have my business name shows up on the caller ID

Everyone was given a direct line in addition to a main office number with extensions, a toll free number and a local number our area and a local number for another state where we do business.

Marketing Director

The intuitive interface guides users through every step, making it effortless to navigate and manage call settings, voicemail options, and even advanced features like call forwarding and auto-attendant.

Director of Quality Assurance

The online Administrator Portal is very user-friendly and allows us to maintain our phone schedules as we need to, and the User Management function allows us to make changes quickly as they occur.

Quality Assurance/Accounts Payable

The biggest benefit for me personally (in my position of Quality Assurance) is the availability to monitor what everyone is doing across our 15 locations using the Nextiva  App, reporting and supervisor dashboard.

The pricing, compared to other platforms, this is always a good option for small companies with teams with no more than 10 people and at very early stages of growth.

for the product/software--we are finding glitches within our call flows when working with tech support more often than not our call flows are interrupted due to internal updates on their side of things to the software causing our phone system to go down therefore costing us business.

System Analyst

The Updates as they are setup with my company require an Admin to login in and accept the updates; if the updates aren't applied the connectivity to Nextiva doesn't work properly; you can't hear others on the phone; need to restart & update in order for the service to work properly.

Senior Team Lead

Coupled with the Unity Client platform, Nextiva provides a comprehensive system that allows me, as a supervisor, to have a firm grip on monitoring and supporting my agents during their shifts.

Nextiva allows me to have one account where I can see all of my numbers, call flows, messages and user in one place.

As a seasoned entrepreneur, I've utilized Nextiva across two ventures, and its consistent reliability, user-friendly interface, and comprehensive features have never ceased to impress me. If you're seeking a communication solution that seamlessly integrates into your business operations, enhances customer service, and provides valuable insights for growth, Nextiva VoIP is the answer.

Head of Customer Success

The platform itself fits all of our needs for a round-robin style call center setup.

IT Engineer

What we like with this camera is the quality of image and voice over chat and it is compatible to almost all online meeting software available.

For my initial onboard call to set up, it was a no call no show due to some issue with the scheduling system.

IT Support Manager

For auto attendants that need different recordings for things like emergency closures or holidays, there is not a third option beyond Business Hours and After Hours that can be enabled quickly.

General Manager

It's been about 3 months and we haven't yet been able to use Nextiva due to the LONG wait to get verified with their campaign registry.
