Zadarma Cloud PBX Reviews & Product Details

We chose Zadarma because we wanted a reliable phone system without adding yet another expensive monthly tool. The built-in PBX features were enough for us from day one. We were able to set up extensions, working hours, an IVR, and routing rules without much trouble. Starting with a single number and a simple menu was straightforward, and it helped us get up and running quickly. Review collected by and hosted on G2.com.

Call recording storage filled up faster than I expected after we enabled recordings for every call. Review collected by and hosted on G2.com.

I work with clients across several markets, so being able to have multiple local numbers connected to a single PBX is extremely helpful. My clients can call a local number, and I can answer from my laptop or my phone without any hassle. I’ve also used it while traveling, and it has been reliable as long as my internet connection stays stable. Review collected by and hosted on G2.com.

It took me a little time to understand which outbound calls were included and which ones were billed separately. During the first month, we reviewed the call reports more carefully to make sure everything matched our expectations. After that initial learning period, it became easy to manage.

Security is my top priority, and this PBX gives me the level of control I’m looking for. I can lock down access with IP-based rules, require 2FA, and stop accounts from becoming shared logins. The permissions are granular enough to maintain good security hygiene without adding unnecessary friction for users. Overall, it feels well controlled while still being practical for day-to-day operations. Review collected by and hosted on G2.com.

Number porting ended up requiring more paperwork than I expected. I understand that this is fairly standard in telecom, but it still slowed down our transition timeline. Coordinating the required documents and invoices with our previous providers took extra time and effort, and made the overall process feel more drawn out than it needed to be.

My main requirement was: “If it doesn’t log in Salesforce automatically, it’s useless.” Once we connected the PBX integration, it started working the way a sales team expects: click-to-call directly inside Salesforce, a caller pop-up when the phone rings, and the ability for new numbers to be created as leads automatically. The best part is that it feels like part of the workflow, not extra admin work, so reps actually use it. Review collected by and hosted on G2.com.

Web calling was the area where we ran into the most trial-and-error. A few reps kept using Safari or Edge out of habit and ran into issues, so we ended up standardizing on one browser and putting together a quick internal “this is the setup we support” doc.

The routing based on CRM ownership works really well for our team. Each client is assigned to an account manager, and the PBX honors that ownership when calls come in, so customers aren’t bounced around through a general line. The call pop-up and automatic logging also feel very natural once the integration is active, especially for setting follow-ups and reminders. Review collected by and hosted on G2.com.

We only discovered there was a Zoho plan limitation when we went to enable the integration. It was a small surprise during setup and meant we had to make a quick adjustment on our side to move forward. Review collected by and hosted on G2.com.

Managing calls for multiple properties used to be messy. With the PBX, we set up separate extensions and call flows for each location while still keeping everything under a single system. The voicemail notifications are especially helpful, because they let us respond quickly to tenant issues even when the office is closed. Review collected by and hosted on G2.com.

The admin panel includes a lot of settings, so it can take a little time to get comfortable and figure out where everything is. After a few days of using it, though, the layout starts to feel familiar. Review collected by and hosted on G2.com.

Starting with a PBX-first approach helped us get into production quickly. The routing, extensions, and IVR handled most of what we needed without having to write any code. When we did need deeper integration, the API made it possible to connect with our internal tools and workflows. Overall, it’s a practical balance: configuration for the core basics, and code only for the edge cases. Review collected by and hosted on G2.com.

If you’re looking for a fully programmable voice app with complex flows throughout, this approach can feel a bit too structured. You’re still working within the PBX model, which may be limiting depending on what you’re trying to build. Review collected by and hosted on G2.com.

Our support desk runs 24/7, so routing rules matter a lot. Zadarma Cloud PBX makes it possible to set up time-based rules, availability checks, VIP routing, and overflow logic without too much trouble. Once everything is mapped out, it runs consistently. The voicemail-to-email feature is also practical—missed calls don’t get lost, and the team can follow up quickly. Review collected by and hosted on G2.com.

On the lower tiers, the limit on the number of IVRs/menus can feel restrictive if you support many departments or multiple languages. We ended up having to simplify our menu structure before upgrading. Review collected by and hosted on G2.com.

Being able to search transcripts saves us a lot of time versus listening through entire call recordings. We rely on them to spot recurring issues, such as missed compliance phrases, weak openings, and repeated customer complaints. We also put together small libraries of “good calls” and “calls to improve,” and then use those examples during coaching sessions. Review collected by and hosted on G2.com.

Transcription minutes are limited, so we have to be selective about which calls we choose to transcribe. Review collected by and hosted on G2.com.

Zadarma is a solid VoIP solution that I primarily use for international calls. The call quality is excellent, and the pricing is very reasonable. I especially appreciate how smooth the experience is on my phone — both incoming and outgoing calls work flawlessly. Review collected by and hosted on G2.com.

The Mac desktop app is less reliable. Occasionally, calls just don’t go through, which is frustrating when I need to make a quick call from my laptop. Also, I receive some spam messages — not sure if it’s the app or just the number I’ve been assigned, but it’s worth noting. Review collected by and hosted on G2.com.
