The best business phone software in 2027

Why does the choice of business phone software matter in 2027?

The copper network, which carried landline telephony in France, is being shut down. According to Arcep, France's telecoms regulator, Orange, which owns almost all of this network, announced its technical shutdown at the end of 2019, business services included. The schedule, split into batches, provides for implementation from 2023 and completion in 2030. The shutdown will affect every user of these services, whatever their provider: if your phone system still depends on these lines, check the date planned for your municipality.

The rules for outbound calls also changed this summer. Since August 11, 2026, commercial cold calling has been banned in principle in France, for companies in every industry. A prospecting call to a consumer remains possible in only two cases: it relates to an existing contract, or the person has given prior consent. That consent lasts one year at most, with no tacit renewal, and the company must be able to prove it obtained it. Calls are allowed only Monday to Friday, from 10 a.m. to 1 p.m. and from 2 p.m. to 8 p.m. (French time), and Bloctel, the French do-not-call registry, ceased to exist on that date.

The number your contact sees on their screen is also checked. In a press release of January 29, 2026, Arcep points out that the law of July 24, 2020 requires carriers to authenticate the caller's number and to cut off calls whose number is not properly authenticated, a mechanism rolled out gradually since October 2024. Reports of number spoofing received by the regulator rose from 531 in 2023 to more than 19,000 in 2025.

How did we rank this software?

To decide between these phone systems and dialers, in October 2026 we read the homepage, the feature list and the pricing grid published by each vendor, and nothing else. No paid subscription was taken out to test the tools, no partnership ties us to the vendors, and displayed customer counts or review scores play no part. Four criteria counted.

1. Inbound call handling. IVR (interactive voice response, the menu that directs the caller), routing by hours or skills, queues, automatic callback, available numbers and keeping your current numbers.

2. Outbound calls. Dialers (power dialer, which works through a list of calls one after another, predictive or parallel mode), voicemail drop, calling campaigns and management of the numbers displayed.

3. AI and integrations. Transcription, summaries, coaching, voice agents that answer in place of the team, and sync with your CRM or your helpdesk (customer support software).

4. A clear offer for a buyer in France. Prices published in euros, whether they are excl. or incl. VAT, minimum number of users, commitment period, options billed separately and a free trial.

The AI receptionist answers, qualifies and books a slot in your calendar during the call. For outbound calls, Allo offers a Power Dialer and a Parallel Dialer that calls 3 to 5 contacts at once. An MCP connector (a protocol that lets an AI assistant take actions in a piece of software) is used to drive Allo from Claude.

Strengths: transcription, AI summaries and native sync with HubSpot, Salesforce or Attio in every paid plan; no setup fee and no commitment; a first support response in 15 minutes on average, according to the vendor.

Limitations: Allo says it targets teams of fewer than 250 people, and the Solo offer is still on a waiting list. Sending SMS uses credits billed in dollars, the AI receptionist and the Power Dialer are paid options, and the vendor states that its prices may still change.

You deploy it on premises, in your private cloud or hosted by 3CX. It relies on SIP trunks, internet phone lines supplied by a carrier, and lets you reuse your equipment if it is compatible.

Strengths: a single annual fee per system, with no per-user cost; a free edition; the vendor advertises no data transfer to third parties, but transcription can go through a built-in server (licenses of 16 simultaneous calls or more) or through Google, OpenAI or Grok: choose according to your confidentiality requirements.

Limitations: several advanced features (built-in transcription server, multi-company, direct routing to Microsoft Teams) are reserved for licenses of 16 simultaneous calls or more ("16SC+" in the vendor's grid). On premises or self-hosted, the phone system is self-managed: allow for configuring the SIP trunks and phones, which the vendor documents in its guides.

Pricing: pricing per system rather than per seat, as an annual fee; free edition available.

Prices and information checked on October 10, 2026 on the vendors' websites.

What should you check before choosing?

1. Can you keep your numbers? Ringover, RingCentral, CloudTalk, Kavkom and Allo advertise porting of your existing numbers, and 3CX makes porting to a SIP trunk provider easier. If your lines still run over the copper network, also find out the shutdown date planned where you are.

2. What is the real price per seat? The entry price comes with conditions: 3 users minimum at Ringover, a minimum number of users at Aircall, 150 licenses and a 3-year commitment for Diabolocom's published price. Total it up over twelve months, options included.

3. Do your outbound calls follow the new rules? Since August 11, 2026, a prospecting call to a consumer requires their prior consent, unless there is an existing contract. See whether the tool helps you respect the permitted hours and keep an exclusion list, such as Kavkom's GDPR blacklist.

4. Will your numbers get through? Ask how the vendor monitors the reputation of your numbers: CloudTalk rotates them automatically, Diabolocom offers a Number Reputation Checker, and Kavkom provides NPVs for automated campaigns.

5. Where does the included AI stop? At Allo and Ringover, transcription and summaries are part of the plans, and Aircall's Essentials offer includes 50 minutes of AI Voice Agents per month; at Dialpad or Diabolocom, AI agents or AI modules are paid separately, through credits or as an option. Test the voice agent on your real customer questions during the free trial.

Where does this ranking stop?

We did not place a single call. Sound quality, the mobile app and support speed are judged through use, and none of them was measured here. The ranking relies on the vendors' sites, read in October 2026; for some of them, our reading of the pricing pages did not yield a clear price in euros, and their profile sticks to what could be read.

Your use matters more than the rank. A five-person firm and a contact center with two hundred agents have different needs: rely first on the Best for lines.

Offers move. Prices, included minutes, AI modules and cold-calling rules change. We will revise this ranking regularly; check each price on the vendor's site before you commit.

How do customers find your number before they call you?

Business phone software handles the calls that come in and the ones your teams make. Before a customer dials your number, there is what they find when they look for a solution on Google or ask ChatGPT which provider to contact. To compare the ways of attracting customers, see our selection of the 50 best channels for customer acquisition in 2026.

Sorank automates this visibility work. The platform, which runs on autopilot, analyzes your presence on Google and in AI assistants, picks the keywords worth going after, then drafts and puts online articles built for AI. For each tracked prompt, for example a question about the best phone system for an SME, you see whether an AI mentions your company. The GEO software page lists every feature. To see what it would look like for your company, book a call.

Conclusion

Three profiles, three choices. A support or sales team that wants a phone system, a call center and AI voice agents connected to its CRM can start with Aircall. An SME of fewer than 250 people that wants AI and CRM sync included, with a price published in euros, should look at Allo. A company that prefers to host its phone system itself and pay an annual fee per system, with no per-seat price, will find what it needs with 3CX.

Before signing, make the most of the free trials: 7 days at Ringover and Allo, 14 days at CloudTalk and JustCall, and for Dialpad's Connect offer.
