What exactly is Google Voice?

Google Voice is Google’s cloud telephony, integrated into Google Workspace. It includes VoIP basics: inbound and outbound calls, transfer, hold, voicemail with transcription, automatic switchboard, use on compatible mobile, PC and landline phones. The tool stands out for its undesirable call filtering via AI, simple number administration and reporting via BigQuery and eDiscovery.

Who is it primarily aimed at? SMEs and teams already using Google Workspace, mainly in the USA and Canada. Number coverage is mainly North American, with unlimited calls in the US and Canada. In terms of quality, Google has announced Voice HD, Opus and G.711 codecs, and data centers in North America. Security: TLS and SRTP encryption, SSO, RGPD compliance.

Feedback from the field: simple installation, clear interface, good call quality. However, some customers report recurring bugs and support that is sometimes difficult to reach.

Rates

  • Google Voice Standard: prices not published; unlimited calls to the USA and Canada.
  • Kavkom for comparison: Telephony Cloud Plus FR/US/CA at €30/user/month; International and Predictive Dialer options available.

 

Market positioning: Google Voice shines if you live in the Google ecosystem, look for Workspace simplicity and call mostly in North America. Kavkom targets SMEs and multi-site structures that want international numbers, an advanced dialer, and French-speaking human support. For those looking for greater flexibility or more human support, solutions like Kavkom are clearly worth considering.

Our review of Google Voice

In use, we appreciate the native Workspace integration, convenient voice transcription, spam filtering and simple deployment. HD call quality proved stable on mobile and PC.

But we’ve seen intermittent bugs, uneven support, and mostly US/Canada coverage for numbers and unlimited. Untransparent rates. For international numbers or French-speaking support, some may prefer a more flexible option like Kavkom.

Here’s a summary of the advantages and points to watch out for.

✅ Automatically transcribed voicemail. At Kavkom, priority is given to recording and supervision.

✅ AI-based filtering of unwanted calls to limit spam.

✅ Simple deployment and administration for IT teams.

✅ HD voice quality announced, Opus and G.711 codecs.

Disadvantages

❌ Coverage mainly US/Canada for numbers and unlimited. Kavkom offers international and unlimited FR/US/CA numbers from €30.

❌ Few advanced call center tools. No predictive dialer or live listening available at Kavkom.

❌ Support in English and US hours. Kavkom offers French-speaking human support.

❌ Bugs and interruptions reported by users. No public status page and no uptime SLA communicated.

❌ Prices with little public visibility. Kavkom displays a clear, no-obligation schedule.

What do reviews and testimonials say about Google Voice ?

Trustpilot Google Voice
Capterra Google Voice

Imagine you’re managing a multi-site sales or support team, and you need a simple tool for calling, receiving and tracking exchanges. Google Voice seems a reassuring option. In this section, we sift through what users say, nothing else. Our aim is to help you see what difference it makes to your day-to-day life, and what you should look out for when comparing it with Kavkom.

 

Overall opinion

Feedback was mixed, with a slight bias towards the positive. Out of 30 reviews analyzed, recurring trends can be observed. On the plus side: easy-to-integrate API, simple installation, clear interface and good call quality. Limitations: frequent bugs, service interruptions and support that can be hard to reach. In concrete terms, it looks like a solution that’s pleasant to deploy and manage on a day-to-day basis, but with technical vagaries and uneven support from moment to moment.

“Google Voice API is easy to integrate and stable, which enables good call and SMS management in our applications.” – Technical integration with API

“Call quality is very good and customer support is responsive and competent. ” – Trustpilot

“Google Voice works well but bugs and interruptions sometimes affect the user experience.” – Google

From an operational point of view, for a growing team, onboarding seems to be a snap, and getting to grips with the system is not time-consuming. On the other hand, recurring breakdowns or bugs can create gaps in the day of an SDR or support agent. For a team leader, this means planning alternatives in the event of an incident. When making a comparison with Kavkom, take a close look at the frequency of incidents reported and the consistency of support over time, as this is a point that impacts service continuity.

 

Pricing & evolution

The reviews do not mention pricing, nor specific points such as volume discounts, ease of increasing or decreasing licenses, or any set-up or cancellation fees. Nor are there any reports of hidden surcharges in this corpus. In short, the subject of price is not documented in these reviews. For a serious assessment, you’ll need to supplement this with direct contractual verification.

If you’re comparing this point with Kavkom, use the same grid: price per user, commitment, conditions for reducing the number of licenses, any fees, and what’s included in the subscription. Here, the reviews on Google Voice don’t give any indicators of field experience on these elements, positive or negative.

 

VoIP features

Users cite three main aspects: call quality judged to be very good, a stable API for managing calls and SMS, and a simple interface that facilitates administration. Nothing is said in these reviews about advanced functions such as power dialer, detailed analytics, recording, transcription, IVR, or live supervision. Instead, the focus is on simplicity and basic robustness, when everything’s running smoothly.

“Set-up is simple and the user interface is clear, making day-to-day administration easy.” – Capterra

“Call quality is very good and customer support is responsive and knowledgeable.” – Trustpilot

For a manager, this means that your teams can get started quickly and without friction, and that your internal integrations via the API have a good chance of being stable. Concrete gain: less time wasted on configuration and maintenance. Risks to anticipate: the bugs and interruptions reported in several reviews can disrupt call campaigns or support during peak periods. If you’re comparing with Kavkom, line up the features that are essential to your use cases, and check the same points for both Google Voice and Kavkom: CRM integrations used, call control, supervision, recording and automation capabilities.

 

VoIP security

The reviews analyzed do not speak directly of security, MFA or authentication. Instead, they mention bugs and service interruptions. This is not security per se, but it does affect perceived availability and operational resilience.

“Google Voice works well but bugs and interruptions sometimes affect the user experience.” – Google

In practice, for a distributed or telecommuting team, these interruptions can generate missed calls, pending customer requests, and pressure on internal support. If you structure a continuity plan between Google Voice and Kavkom, expect the same level of requirements on both sides: failover methods, simple procedures for rerouting calls, and clear instructions for your agents in the event of unavailability.

 

Steering & KPIs

The piloting aspect is particularly evident in the API. Users note an API that is easy to integrate and stable, enabling them to manage calls and SMS messages in their applications. Nothing is reported about real-time dashboards or exports integrated into the interface. So, on the basis of these opinions, we’d say that it’s better to manage calls “via API”, connected to your business tools, rather than through the native interface.

“Google Voice API is easy to integrate and stable, which enables good call and SMS management in our applications.” – Technical integration with API

For a team manager, this means you can centralize call and SMS data in your own tools if your technical team knows how to consume the API. In comparison with Kavkom, ask exactly the same questions of both solutions: API depth, available data, stability, quotas, and integration effort for your key KPIs such as response rate, average duration, and volume distribution.

 

Phone number availability

None of the notices selected mention issue coverage, selection by country, region or city, or portage. It is therefore not possible to draw any conclusions on this aspect from this database.

If this is a key criterion for you, check the same criteria as for Google Voice and Kavkom: list of countries and types of numbers, porting times and conditions, and any gaps in coverage. The reviews we’ve analyzed don’t provide any evidence one way or the other.

 

Support & responsiveness

This is the point of greatest contrast. Some praise responsive, competent support. Others report difficulties in reaching support, and bugs that are not quickly resolved. This experience gap can be explained by different situations, but it recurs too often to be ignored in a serious evaluation.

“Call quality is very good and customer support is responsive and knowledgeable.” – Trustpilot

“Customer support is difficult to reach and any bugs present are not dealt with promptly.” – Trustpilot

Business impact in plain English: in the event of an incident in production, you can either recover quickly or remain stuck for longer, depending on the queue and the effectiveness of the follow-up. For a team that can’t afford downtime, anticipate a simple protocol: who contacts support, what channel, what SLA is expected, and what Plan B if resolution is delayed. When comparing with Kavkom, investigate the same concrete points: average response times, handling of complex tickets, follow-up until resolution, and feedback from teams similar to yours.

 

Third-party integrations

The reviews don’t mention any specific CRM or business tools. The only clear angle is the stable, easy-to-integrate API, which lets you manage calls and SMS from your applications. This is a good signal for interoperability, without detailing the depth of ready-to-use connectors.

“Google Voice API is easy to integrate and stable, which enables good call and SMS management in our applications.” – Technical integration with API

For a decision-maker, this means that integration is probably feasible quickly if you have developers. In comparison with Kavkom, ask the same questions of both solutions: native integrations available in your stack, synchronization latency, automatic creation of records, call feedback, and possible limits per plan. Google Voice reviews don’t give any indication of these details, only positive feedback on the API.

In summary, Google Voice is perceived as simple to deploy, pleasant to administer, and backed by a reliable API, but with bugs and interruptions that come up regularly, and support experienced as variable. To make a proper comparison with Kavkom, keep the same grid on each point, and validate the elements missing from these reviews with a test or a contractual discussion.

Conclusion: should you take Google Voice, or turn to another solution?

Google Voice is right for you if you’re already on Google Workspace, with teams based mainly in the USA and Canada. You’re looking for easy-to-deploy telephony, calls/voicemail with transcription, spam filtering, light administration and a stable API for integrating calls/SMS with your tools.

Avoid if you need international numbers, advanced call center features (predictive power/dialer, live supervision), French-speaking support or non-US hours. Points to watch: bugs and interruptions, uneven support, pricing not easy to read publicly, coverage mainly US/CA, advanced reporting mainly via BigQuery.

On the Kavkom side: international and unlimited FR/US/CA numbers from €30, predictive dialer and live supervision, French-speaking human support, commitment-free public rates, ready-to-use dashboards and RGPD focus for multi-site or growing teams.
