Looking for a reliable RingCentral review for your business telephony? We sift through the reviews: what works, what doesn’t, and when the promise delivers.
On the menu: price plans, call quality, analytics, IVR, contact center, CRM integrations, support and billing. We’ll put this feedback in perspective with the market, including Kavkom, to make confident decisions.
RingCentral is an all-in-one cloud communications platform for businesses. It combines HD VoIP telephony, team messaging, videoconferencing and an omnichannel contact center with skills-based routing. Telecom coverage is extensive: local numbers in 45+ countries, unlimited calls to 99+ destinations depending on packages. On the reliability side, the editor announces a 99.999% SLA, data centers in 3 regions and security certified ISO 27001, PCI DSS, TLS 1.2 and AES 256 encryption, RGPD with EU/NA residency.
For whom? From SMEs to major accounts, especially support teams and contact centers that need real-time analytics, AI transcriptions, supervision and integrations (Salesforce, Microsoft Teams, Zendesk, Google Workspace).
Day-to-day operation: automatic switchboard, queues, recordings, meeting transcription and summaries, virtual assistants. Customer reviews are divided: many praise the powerful dashboards, smooth CRM integration and stable calls. Others report breakdowns, bugs, hard-to-reach support and opaque billing.

Quick comparison: RingCentral shines in global omnichannel, AI and multi-site coverage. Kavkom focuses on sales productivity with a native predictive dialer, simple start-up and human support. For those looking for greater flexibility or more human support, solutions like Kavkom are clearly worth considering.
In use, we appreciated the international coverage, AI for transcriptions and real-time analytics with clear reports. CRM integration is smooth, voice is generally stable, and the advertised SLA is reassuring.
But we’ve also seen reported breakdowns and bugs, hard-to-reach support, opaque billing and high prices that aren’t publicly displayed. This can be a deterrent for SMEs looking for visibility and flexibility.
Here’s our table of strengths and limitations to help you make the right decision.
✅ Extensive global coverage and calling (numbers in 45+ countries, unlimited to 99+; Kavkom covers 50+ countries and offers unlimited FR/US/CA as standard)
✅ Advanced omnichannel contact center (skill-based routing, supervision; Kavkom prioritizes predictive dialer for prospecting)
✅ Real-time analytics and useful AI (transcripts, summaries; Kavkom provides sales-oriented dashboards and live listening)
✅ Wide native integrations (Salesforce, Teams, Zendesk; Kavkom integrates Zoho, Salesforce, HubSpot, Pipedrive, Zendesk)
✅ 99.999% SLA and security certifications (ISO 27001, PCI DSS; Kavkom encrypted and RGPD, SLA not publicly displayed)
❌ Support hard to reach and variable (mixed customer reviews; Kavkom offers direct French-speaking support without premium tier).
❌ Breakdowns and bugs reported by users (outages, apps that crash; Kavkom focuses on simple startup and rapid assistance in the event of an incident).
❌ Prices not very transparent and perceived high (prices not published, billing considered opaque; Kavkom displays its prices, without commitment and pro rata).
❌ Onboarding and migration not well defined by default (assisted migration not included; Kavkom supports configuration and portability)
❌ Few public technical metrics (no status page or MOS communicated; Kavkom provides call statistics and diagnostic help)
❌ Rich but complex suite for small teams (heavier administration; Kavkom remains lighter for rapid deployment)
Kavkom corrects the limitations of RingCentral: no-commitment, pro-rata pricing, direct French-speaking support and assisted start-up.

Imagine you’re managing a multi-site sales or support team. You’re looking for stable, controllable cloud telephony, connected to your CRM. RingCentral looks solid on paper. In this section, we sift through what users are saying in their online reviews to help you visualize the impact on a daily basis.
Out of 30 reviews analyzed, the trend is divided: 14 positive, 5 mixed, 11 negative. On the positive side: useful dashboards, CRM integration that facilitates workflow, and stable calls when everything’s going well. On the negative side: sometimes prolonged breakdowns and bugs, customer support that’s hard to reach or uneven, and billing problems reported by some.
“RingCentral offers extensive dashboards to monitor efficiency. Calls are stable.” – Capterra
“Outages for several months… no follow-up to emails sent.” – Trustpilot
Operationally, this means that your manager can monitor the KPIs live and coach his teams, but that you need to anticipate workarounds in the event of an incident or slow support. For a growing team, the analytics part is a real plus. On the other hand, if your business doesn’t tolerate interruptions, the risk associated with breakdowns and support reactivity needs to be considered.
The reviews do not detail tiers or public prices. They mainly refer to the perception of cost and the quality of billing. A number of returns speak of a price deemed high, and of opaque or confusing billing in some cases.
“The product offers a lot but the cost is significant.” – Capterra
“Opaque billing and unresolved billing issues.” – Trustpilot
As far as budget management is concerned, this feedback means that you need to clearly define the scope of the project before deployment: what is included per license, any add-ons, conditions for reducing the number of users, and how disputes will be handled. If you need to adjust your headcount quickly (seasonal workers, SDRs ramping up or down), advisors suggest anticipating exchanges with finance and support to avoid invoice misunderstandings. No information on volume discounts in these notices.
What users appreciate most here: the dashboards and steering tools for monitoring performance, a CRM integration that’s deemed fluid, and call quality that’s often stable under normal conditions. One review even notes an ergonomic interface and recently improved support.
“Very satisfied with the integration with our CRM. Call quality and stability are excellent.” – Google
“RingCentral is comprehensive, with good management tools and an ergonomic interface.” – Trustpilot
On the irritating side, negative reviews insist on bugs and crashes, dropped calls, and sometimes ergonomics deemed unsuited to their context. For a team manager, this means a double scenario. In the best-case scenario, your agents benefit from a clean CRM flow and useful coaching stats. In the worst case, call interruptions and crashes can cause productivity to plummet and follow-up to seize up.
“Calls are often dropped and the app crashes regularly.” – Google
In concrete terms, for a call center, the CRM integration plus analytics combo is a real lever for reducing re-keying and identifying bottlenecks in real time. But if your network or application environment is sensitive, you need to set up fallback procedures and reinforced technical monitoring on high-volume workstations.
The reviews analyzed do not explicitly mention encryption, MFA, SSO or compliance. They mainly refer to operational reliability through failures, crashes and instabilities. There are no direct reports of security flaws in these testimonials, nor any particular praise for security mechanisms.
“Recurring breakdowns… customer service is deplorable, emails left unanswered.” – Trustpilot
In practice, this doesn’t mean that there is no security, just that users don’t mention it in their feedback. For a multi-site team, the most important thing to remember here is the dependence on service stability and the importance of reactive support in the event of an incident. In the absence of a clear signal on the security side in these reviews, the main risk evoked remains unavailability and its consequences on business.
The positive feedback is clear: comprehensive dashboards, powerful steering tools, visibility on efficiency. For a manager, this translates into the ability to track call volumes, spot quality drops, compare performance, and make rapid decisions on queue organization or training.
“Powerful management tools and extensive dashboards. – Capterra and Trustpilot
On a day-to-day basis, this can save time on team meetings and variance analysis. The reviews don’t mention APIs or export options, but the described use of analytics in practice indicates an already exploitable reporting base. For growing operations, this is a strong point, as you can standardize your steering rituals and objectify coaching.
The reviews do not detail country coverage or number type (geographic, mobile, special numbers). Nevertheless, one point stands out: number portability was experienced as fluid by at least one user.
“Portability worked perfectly.” – Capterra
In concrete terms, if you’re migrating from an existing system, this feedback reassures you about the continuity of service linked to porting. None of the other reviews mention coverage gaps, city selection or toll-free numbers. So, for international expansion, you’ll need to check availability on a case-by-case basis before committing to a timetable.
This is the most mixed subject. Several reviews note support that is absent, slow or difficult to reach, sometimes over long periods, with unanswered e-mail exchanges. Other testimonials mention support that is present and improving, or even very available.
“Customer support nonexistent.” – Trustpilot
“Support has improved recently.” – Trustpilot
“Very present customer support.” – Capterra
For an operations manager, the consequence is clear: depending on the context, you can either have a rapid resolution, or a waiting time that puts your business at risk. If your teams depend on uninterrupted 9am-7pm availability, have an internal escalation plan, alternative contact channels, and team documentation for recurring incidents. In finance, some of the reports of confusing billing mean that you need to secure a validation circuit and protect your termination or modification dates with written proof.
Reviews focus on CRM integration. Positive feedback cites seamless integration with their CRM and pleasant day-to-day use, suggesting call synchronization and a unified agent experience. No reviews detail which specific integrations, nor their availability according to plans, nor the presence of an API.
“Simple CRM integration, stable and clear calls.” – Google
On a day-to-day basis, for a sales team, this means fewer double entries and better traceability of exchanges. For a manager, it means time saved on reporting and better control of the pipeline. In the absence of details in the reviews, if your stack includes several tools, it would be wise to test the integration on your real cases before a large-scale deployment.
RingCentral is relevant for support teams or omnichannel contact centers requiring real-time analysis, AI transcriptions and CRM integrations (Salesforce, Teams, Zendesk). Its broad coverage (45+ country numbers, unlimited to 99+) and 99.999% SLA reassure multi-site organizations with already structured processes.
Conversely, reviews point to failures/bugs, hard-to-reach support and opaque billing with unpublished prices. Not ideal if you require budget visibility, rapid deployment, variable staffing levels, or if your business doesn’t tolerate downtime.
In these cases, Kavkom favors operational flexibility: public prices, no commitment, prorata, direct French-speaking support and assisted start-up. You keep the essentials (cloud telephony, CRM integrations, 50+ country coverage) with a sales focus via predictive dialer, dashboards and live listening, in a lighter-to-deploy tool.
