Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 9 of the 44 other business phone systems we grade
Zultys sells a business phone and unified communications platform with an integrated contact center, delivered as hosted cloud, on-premises, virtual or a hybrid built on its Hardware as a Service model. Users reach it through the ZAC desktop app, a browser version and mobile apps. Pricing comes by quote.
To get you started, here are 7 things to know about Zultys, taken from its own pages and our grades.
No prices are published and it sells through channel partners, so you request a quote or a demo before you see a number.
- 1
Best for mid-size offices that buy through a reseller
Zultys sells a phone system and contact center in one app, as cloud, on-site or hybrid, with transcription and an AI receptionist.

Keep it
To replace Zultys you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for mid-size offices that buy through a reseller
Zultys sells a phone system and contact center in one app, as cloud, on-site or hybrid, with transcription and an AI receptionist. No prices are published and it sells through channel partners, so you request a quote or a demo before you see a number.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No price is published; the site asks visitors to request a quote or demo, so it sits at the middle. |
| Free plan and trial | F | No free plan and no trial on the pages read. |
| Features | B | Voice, SMS, chat, video, conferencing, presence, a contact center and AI transcription in one interface, with cloud, on-site or hybrid choices. Some AI tools are listed as separate products with no price shown. |
| Ease of use | C | No store rating on record. Choosing a deployment and buying through a reseller are part of the work. |
| Platforms and integrations | B | ZAC for Windows and Mac, a browser version and mobile apps for iPhone and Android. No integrations or API are listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Zultys is for
- Fits if you want cloud, on-site or hybrid from one vendor
- Works for contact centers that want the dialer in the same app as the phones
Who it is not for
- Skip it if you want to see a price first, since the site asks for a quote or demo
- Not for you if you want to buy direct, because it says it sells through channel partners
- Watch out: the AI Receptionist and some AI tools are separate or newer products with no price shown
- Watch out: no free plan or trial is listed

Its grades against its category, and whether to keep it or make your own
9/44
Other business phone systems it is graded above
Zultys's GPA of 2.0 is higher than 9 of the 44 other business phone systems we grade, and level with 10.
It stands best on features (B, above 26 of 44) and worst on free plan and trial (F, above 0).
Each grade against the category
Every bar is all 45 business phone systems we grade, cut by the letter each got. Zultys’s own letter is outlined.

- FFree plan and trialAbove 0 of 44
- BFeaturesAbove 26 of 44
- CEase of useAbove 4 of 44
- BPlatforms and integrationsAbove 6 of 44
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Zultys you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 25 of the 44 other business phone systems grade higher.
What you could not
- Phone numbers and calls carried over the phone network.
- Video calls.
- Chat that a whole team counts on staying up.
- Texts from a business number, registered with the carriers.
- Speech turned into text you can trust.
- Apps for macOS, Windows, iOS and Android that stay in step with each other.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Zultys’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
