You’re looking for a clear review of JustCall for your business telephony. Here, we sift through customer feedback: strengths, limitations, and for whom it’s really suited.
We evaluate price, features (IVR, SMS, AI, CRM integrations), call quality, support and billing, then compare these points with Kavkom. Enough to decide quickly, without jargon.
JustCall is a cloud telephony platform designed for sales teams and call centers. The tool centralizes VoIP calls, SMS/MMS and WhatsApp, with a simple dashboard to manage queues, transfers, recordings and outgoing campaigns.
For productivity, JustCall relies on AI: real-time transcription, sentiment analysis, agent coaching, and automatic dialing to speed up call cycles. CRM integrations cover Salesforce, HubSpot, Zoho, Zendesk, Pipedrive, Freshdesk, Zapier and Make, making it ideal for teams already equipped with the right tools.
International coverage with local numbers in 58+ countries and unlimited calls to key destinations such as France, the USA, Canada and the UK. Industry-standard security with TLS/SRTP and RGPD compliance. Audio quality is described as clear, HD voice, low latency. No public data on SLA or status page.
JustCall prices: three plans (Basic, Pro, Enterprise); prices not published in available sources. For context, Kavkom displays public rates with no commitment and on a pro rata basis, e.g. cloud telephony from €10 excl. tax per user and unlimited FR US CA at €30.
Customer feedback: intuitive interface, quick installation, good value for money and responsive support. But feedback also speaks of bugs, outages, sometimes slow support and confusing billing. Useful to keep in mind for a critical deployment.
JustCall is suitable for SMEs and multi-channel teams who want AI, SMS and CRM integration without hardware. For those looking for more contractual flexibility or more human support, solutions like Kavkom are clearly worth considering.

Custom demo
Imagine you run a sales team or a call center, and you’re looking for cloud telephony that’s easy to deploy, stable and connected to your tools. JustCall seems like a good idea. To find out, we analyzed user reviews published on Google, Trustpilot and Capterra. Here’s what’s coming back, and what it means in concrete terms for your operations.
Feedback is mixed. Some customers emphasize the intuitive interface, good call quality and advanced features such as call planning and automated SMS. Examples of positive feedback on day-to-day reliability, particularly in call centers.
“Intuitive interface, good call quality with very little latency. Advanced phone features like call scheduling and automated SMS.” – Google
“Very responsive support and reliable tool… the platform is reliable for call center call management.” – Trustpilot
However, feedback points to occasional bugs, variable sound quality, instabilities and outages, and support that is sometimes difficult to reach. For some, it’s a real headache to use.
“Interesting features but occasional bugs and some sound quality issues.” – Google
“Recurring bugs and hard-to-reach customer support.” – Trustpilot
In practice, for a manager, this means two things. On the one hand, your teams can move fast thanks to the ease of use. On the other, you need to anticipate instability peaks that disrupt call volume and listening quality at busy times. In comparison, Kavkom’s offer focuses on cloud stability and real-time supervision to secure critical time slots. For a call center that operates around the clock, this is a point to be weighed against your requirements.
There are no price quotes for JustCall in the reviews. On the other hand, price sentiment is mixed. Some small and medium-sized business customers described JustCall as offering very good value for money. Others consider the price to be high for small structures, with a mixed quality/price ratio.
“Excellent value for money… great reliability on call quality and features offered.” – Capterra
“Comprehensive features but a price that remains a drag for some small businesses.” – Trustpilot
As for invoicing, several opinions point to confusion and support delays that complicate the resolution of disputes.
“Unclear billing and long response time from support.” – Trustpilot
In concrete terms, if you need to adjust the number of users up or down each month, a simple, transparent model is key. Reviews don’t mention JustCall’s contractual flexibility. On the Kavkom side, public rates are clear and commitment-free, with offers starting at ≈ €10 ex-VAT per user for Basic and unlimited FR/US/CA packages starting at ≈ €30 ex-VAT. For a fast-moving team, the ability to reduce or increase licenses without friction plays into your monthly costs and cash flow.
What users like about JustCall.
“Simple installation with a clear interface, call management is intuitive and efficient. ” – Capterra
What stands out on the limits side
“The platform regularly encounters instabilities and outages, affecting communication.” – Google
Operationally, this means that rapid onboarding is likely, but that fallback procedures must be in place if quality deteriorates during a campaign. In comparison, Kavkom focuses on an advanced predictive dialer, supervision tools and deep CRM integrations for sales and support productivity. If your priorities are intensive outbound automation and live coaching, check whether the JustCall modules used by these customers cover these use cases without overlay.
The notices analyzed do not discuss encryption, SSO or MFA. They mainly describe perceived risks via call instability and disconnections. From an operational security point of view, the impact is clear: loss of conversations, callbacks to manage, lower NPS if customers call back several times.
“Instability and frequent outages… impact on communication.” – Google
Tip from the feedback: if you choose JustCall, plan for dual Internet connectivity at your critical sites, and reliable wired headsets to limit variables. For comparison, Kavkom documents a resilient cloud infrastructure and real-time call flow control. This doesn’t replace your good network practices, but it does reduce the perceived risk in reviews.
The reviews don’t detail JustCall’s dashboards, exports or APIs. Instead, they talk about efficient day-to-day call management and a comprehensive platform. What’s missing is concrete feedback on real-time KPIs or the depth of statistics.
“Comprehensive platform and efficient support.” – Trustpilot
For a Head of Sales or call center manager, this means checking the available metrics: agent status, waiting time, pick-up rate, call logs, CSV or API exports. On the Kavkom side, statistical monitoring and live listening are emphasized for coaching. The comparison must be made feature by feature on your perimeter, as JustCall reviews do not give quantified details.
The returns analyzed do not address geographical coverage, the type of numbers available, selection by city, or porting. This means that there is no positive or negative signal in these notices on this aspect.
“No comments on numbers or portage in the notices consulted.” – Summary
If your deployment depends on local numbers in several countries or mass porting, ask for written confirmation and test a pilot batch. Kavkom’s offer mentions international numbers and multi-country capability. The comparison should be made list in hand, country by country, before planning your expansion.
Here, experiences differ widely. Many customers praise the responsive, attentive support that makes their teams’ day-to-day work easier. Others describe support as hard to reach or slow, particularly when it comes to billing issues.
“Support is available and efficient.” – Trustpilot
“Hard to reach support… complicated usage.” – Trustpilot
“Unclear billing and long response time from support.” – Trustpilot
In practice, for a revenue-based team, a critical ticket not handled has a direct cost. Lost leads, lost appointments, lost revenue. If you opt for JustCall, set up an escalation channel, clarify SLAs, and test support during the trial. On the Kavkom side, fast, French-speaking human support is positioned as a differentiator. This can reduce operational risk when an incident occurs at 9am on a Monday morning.
Reviews speak of a comprehensive platform and good functionality, but don’t mention specific third-party tools or the depth of integrations. Nor is there any mention of limits per plan.
“JustCall offers a complete platform…” – Trustpilot
If your workflow depends on a deep CRM integration with automatic records, call logs and click-to-call, validate point by point in a demo. Kavkom’s announced native integrations cover Zoho, Salesforce, HubSpot, Pipedrive and Zendesk, with an open API. To make the right decision, compare your key scenarios, for example: automatically open the contact form when the call is taken, upload records to the CRM, and export KPIs for your reports.
JustCall is ideal if you’re looking for multi-channel cloud telephony (voice, SMS, WhatsApp) with CRM integrations and AI modules (transcription, coaching). The interface is simple, number coverage is extensive (58+ countries) and sales/support teams can deploy quickly without hardware.
On the other hand, reviews report bugs/outages, uneven support, confusing billing, unpublished prices, no SLA or status page, and no assisted migration. Avoid for mission-critical environments, variable staffing levels or advanced compliance requirements.
On the Kavkom side, you get public pricing, no commitment, pro rata billing, resilient cloud infrastructure, TLS/SRTP, French-speaking human support and guided migration within an RGPD framework. Relevant if your priorities are stability, budget visibility and support.
