Telzio has been rock-solid from the ease of use on the administrator side, to the ease of use for our users, to the support we've received. Very happy with Telzio as our VoIP vendor. I have no plans to make any changes any time soon.

I like the pricing structure. Pricing by the minute instead of by the user or line saves us so much in telephony costs. It's not for everyone; but for us, it was integral over other options we looked at that charged by the user or line.

I thought the mobile app was the weak point at first but it's been steadily improved over time and is very solid now.

Fantastic, if I had to outfit a small office or start-up, this is where I'd begin

I love that I could just jump headfirst into Telzio without an unneeded sales call telling me what I needed. I knew what we needed, a basic phone system - nothing with video calls and everything else. We have been through a couple providers and it always seemed like the feature we needed was behind a more expensive plan. With Telzio, everything is included and you just choose what you need for minutes, which in case you're wondering - you probably do less minutes than you think - I was shocked at how low our usage was. Telzio is extremely easy to use and compatible with so many different office phones that nearly everything from our old system flawlessly transferred to our new one. I can't say enough good things!

The only thing I'd nitpick is setup of caller ID name and e911 have an initial fee - I didn't mind paying them but it would've been nice knowing that going in those were not included in the initial startup cost.

Great offering of features and voice overs

Paid 400% of my monthly fees in overages. They said well we sent you emails...which means they aren't willing to help. Cannot do business with a company that operates on a "gotcha" business model.

We have no plans to transition away from Telzio in the foreseeable future. The reliability of the service is commendable, as we have yet to experience an outage or any issues in the 2 years we have been using it!

Telzio offers a user-friendly experience with its straightforward setup and easy configuration. Should you require physical phones, they conveniently ship them to you, requiring nothing more than a WiFi password on your part. The phones arrive preconfigured to your account, making the process hassle-free and efficient!

Telzio demonstrates promise and I am hopeful for its expansion to integrate with other third-party applications. There's room for enhancement in its security features for administrators, notably the absence of Google Single Sign-On (SSO), though it's heartening to hear that a substantial update in 2024 aims to address these aspects.

Overall Telzio is a wonderful VOIP system. Our team uses it globally, with many DID in many countries. The setup was slick and straightforward. IOS & Android APP and web browser access. The support team is very helpful and reply quickly via the live chat. BIG FAN of TELZIO!!

Telzio Voip is a wonderful, feature rich, solid and affordable system. Everything works and works well. The cost to add a DID is very inexpensive. The support team is knowledgeable and friendly.

Telzio VOIP System is all good. The one thing I can think of is that when you have all your users entered, if you delete a user (if they have left the business) they are gone so I just remove the extension number from the user instead and keep the user......endless number of users.

Overall, we are highly satisfied with Telzio. Since our initial test, we've moved virtually all of our clients over to Telzio. The ease in which we can set up, make changes and receive customized personal help has been truly remarkable. We've worked with a number of providers and this by far has been our favorite experience.

Strongest feature by far for us has been how user friendly setting up Call Flows are. Because we are able to manage users, devices, call handling on such a granular level, we can truly direct our callers where we need them when and how is best.

The online Telzio calling features aren't as strong as they could be. We'd love to see a desktop app instead of needing to use a web based calling system.

It was very east to setup and customize our IVR for multiple retail locations using Telzio.

Nothing, really. I could understand why this software wouldn't be appropriate for enterprise level business, but for our small chain of dispensaries it's exactly what we were looking for.

Telzio has been perfect for our organization. We are a seasonal business and go from an off-season usage of about 30 users to 200 or so for 3 months a year. The pay by usage model has saved us low 5 figures per year, even when accounting for having to purchase all new hardware during year 1. The service is reliable, easy to use and tech support is excellent. Honestly, no complaints at all!

The admin control panel is excellent, easy to use, and has modern UI. All services have been reliable and interactions with tech support friendly and informative.

The mobile app sometimes has connection issues but that is more likely network / LTE related.

Highly reliable, I do not have to deal with it often. Setting up new employees is a breeze.

Easiest setup of a VOIP solution I have seen. Highly Reliable

Pricing is a bit difficult to measure starting. Worth it for the savings.

Telzio has allowed my company to have an easy to use but great company phone system. You can set it up so that not everyone that is on the system will receive every call. We have 3 different phone lines that come into ours, and it is very easy to tell what phone line the incoming call dialed. Also it is very easy to place a call on hold, or transfer to another person. Use can also use it to inter-call between the company. Through the website you can also send text messages and fax.

How easy it is to use. You sign up, and then can start using. It takes no time to get used to the setup, and is very user friendly.

It does not often work great if you start a call on Wifi and then need to switch to cellular data, most often it will loose the call.

We use Telzio as for our clients to contact us for customer support and purchasing. It works exactly as advertised and it has been simple to implement, add users, add different call flows, and track employee calls. The follow up from your customer support and sales team has been exceptional. They have followed up with me regarding features and requirements that amidst a company merger I often had far in the back of my mind but needed to get done.

The interface to setup call flows is very simple, flexible, and immediate. Usage data presentation is attractive and fairly easy to extract for reporting purposes.

There are features that are not yet implemented that would be nice. Better text message support (ie 5 digit text numbers in particular). Also, ringing folks in a queue in the same order every time opposed to the person who hasn't received a call in the longest time.

I have realized it is way easier to contact customers with everything readily available to me in one place. This allows for our remote employees to not miss a beat as well. I especially enjoy that customers will not have my personal phone # when I call through the Telzio app.

Instead of having 3 phone numbers that our customers call, we now have one that our customers can use to call each of our locations! This makes it so that I and others can see and respond to calls for Site #1 while we're at Site #3 or home. Once set up, it's very user friendly.

There is a lag once I answer calls where the caller won't hear me. Other than that, no complaints.

Our medical practice has lost HUNDREDS of clients because of an issue with this app and we got about [SENSITIVE CONTENT] back

The ease of using on multiple devices, I like the ability to set up different call flows

interface hard to use, voicemails are easy to miss, customer support is suboptimal. You ask for features they don't get done and you only realize a year later when you would have desperately needed a conversation to get recorded. Point of contact is defensive and not taking responsibility

Great! No problems so far!

Easy to configure and manage at any point in time. I love it’s all done with the drag-and-drop feature. I could honestly manage everything myself without having to learn the system, and our office manager was able to take over without any training or leaning curve.

Nothing really. Does what it says on the tin.

Was possible to use phones we already had,

That music plays before letting caller know they have reached Crest

Customer service is helpful. HIPPA compliant. Great quality for the price. Love the cloud interface of phone, text, and fax.

I wish we could use the physical fax machine (with the ATA) and the cloud fax option. It is tough on the business that we can't do both.

A residential apartment complex we manage was destroyed during hurricane Ida, leaving hundreds of residents as well as out office staff displaced. We were able to instantly set up emergency toll free numbers for the residents to call for support and information. We were also able to instantly transfer all calls from our now submerged management office to the office staffs cell phones via the telzio app. Because of Telzio we were able to maintain communication with our residents and staff, allowing us to assist and relocate all of our residents. All of this set up in under an hour.

The support team behind the product is the best feature of this product.

Admin tools on the app would be appreciated. The app could use a GUI update.

I no longer need someone to answer calls, I can get back to clients quickly.

Ease of use, great customer support, great product and great results, best price

The translation of voicemail needs to be a little clearer.

The staff are great to work with, and you can add multiple team members along with tracking text messages!

Missing some support in labeling contacts and phone number that we call to keep track of clients we have been talking to

Telzio is easy to use and configure for someone who is not experienced in VoIP technology. It's also highly adaptable in the range of products that can be used with the service.

It would be nice to have a call flow extension that could forward directly to an external number (instead of having a register a new user).

Overall my experience so far with Telzio has been really good. I was looking for an effective alternative to Dialpad and it's proven to be a good one.

I think that Telzio has a super clean and functional user interface. The platform is easy to use and integrate and the mobile app provides full featured functionality on the go, which is a must for any modern professionals business phone needs.

The only thing thus far that I don't like is the number to plan assignment requirements. It seems somewhat counter-intuitive and not super easy to understand.

Wonderful customer service. Barely any issues and the issues that did arise were taken care of quickly.

There were minor issues occasionally....

Great Service! Highly recommended, Very friendly Support team willing to help. I been looking now for a service that had everything we needed. Now I'm excited that I found a service that has everything I needed plus much more for a great cost also. So far loving the new service. Nothing bad to say.

Nothing bad to say about the service since we been with them

So far there are no complaints. The service seems reliable and consistent. I look forward to see the success in the future.

All the features we needed in one place. High level of security and confidentiality is what we needed.

Website took a minute to get used to, but the customer service to help navigate the trouble was outstanding.

Telzio’s services allow for a comprehensive hotline structure that is extremely user friendly. Unlike other providers, Telzio provides every service with the various plans and allows ownership of vanity numbers. Our designated rep has been completely accessible and supportive.

No cons to report at this time. Thank you.
