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.
