1. Quo — Micro-teams of 2 to 5 working mostly on Wi-Fi

Shared business numbers, texting and AI call summaries for small teams, formerly OpenPhone. Call reliability off Wi-Fi is the recurring complaint, and there is no video conferencing.

My take: Updated 25 October 2026. Selection criteria: required call workflow, eligible team size, billing term, destinations, included usage and ability to retrieve data. The numbers label the existing comparison order; they are not measured quality scores. Only CloudTalk has a hands-on result discussed below, and that result covers contact handling rather than calling. Choose this row when the buying problem is a shared phone inbox for a micro-team. Our dossier places it with teams of two to five working mostly on Wi-Fi. It also records recurring complaints about reliability away from Wi-Fi; those are dossier reports, not a network test we performed. Trial the service on the mobile networks and locations you actually use before moving your business number. Check an answered call, an unanswered call and a handover between colleagues rather than judging only the interface. Treat each failed path as a reason to keep the existing service until you understand the cause. Use the dated pricing discussion in our review and request the complete checkout total rather than treating the table as a computed quote. The dossier price reading is 11 October 2026. A low headline seat price does not establish the cost of extra numbers, international calls, messaging registration or the AI answering allowance. Ask which of those you need and retain the answer alongside the quote. Read our full Quo review →

2. CallHippo — Virtual numbers in 50+ countries on a budget

AI-driven business phone system. Virtual numbers in 50+ countries, power dialer, call analytics and AI agents — set up your sales and support calling in minutes.

My take: Compare this with a virtual-number service for a team that needs CRM connections, then make the destination list the deciding test. Our dossier reading of 14 October 2026 says the unlimited allowance is for domestic US and Canadian calls; it does not establish an unlimited international package. Write down where your customers are, where your staff call from and whether they call landlines or mobiles. Ask for those routes to be priced separately. The current dossier also corrects an important free-plan assumption: Basic is free for the first six months, after which the account must move to Starter to continue. That makes it an evaluation runway rather than a permanent operating budget. The table summarises the subscription terms in our review; it does not compute the international calling bill for your destinations. Do not carry the old two-user minimum into a quote: our latest browser reading says it was no longer displayed on the Starter card. We have not tested calling or migration here. Require a trial using your own destinations before relying on the allowance. Read our full CallHippo review →

3. Aircall — Sales and support teams of 3+ working in their CRM

Cloud phone system for sales and support teams: call routing, analytics and CRM integrations.

My take: Use the licence floor as an eligibility check before comparing features. The Aircall Essentials pricing terms, read 10 October 2026, is $30 per licence per month billed annually or $40 monthly, with at least three licences. A solo operator or pair therefore still buys three licences. The documented plan includes routing and analytics for teams working in a CRM or helpdesk, but inclusion of a feature does not demonstrate your integration is configured correctly. In a pilot, make a call from a contact already in your helpdesk and another from an unknown number, then inspect where each record lands. Our support-system blueprint describes a documented Freshdesk integration; we have not tested that integration end to end. The US pricing dossier limits the unlimited calling wording to the US and Canada. Price international routes and optional features separately. Keep the currency and country selector on the saved quote, because our dossier records the Netherlands storefront using the same numerals in euros. We have not converted those prices or ranked this service against a euro quote. Read our full Aircall review →

4. CloudTalk — Call-centre routing and analytics for support and sales

Cloud call centre with call routing, analytics and CRM integrations, priced per user; the Expert tier needs at least three licences.

My take: The CloudTalk rules, read 6 October 2026 in euros, put Lite at €19 per user per month on annual billing or €27 monthly; Starter at €25 or €34; Essential at €29 or €39; and Expert at €49 or €69, with at least three licences for Expert. Compare the plan you need and the extra usage separately. Our hands-on session on 24 October imported two synthetic contacts by CSV. Both rows reported success with a runtime of zero seconds, but the list remained empty until a reload more than ten seconds later. Title, company, city, country and email survived; the template separator split the tags as expected. That supports a contact-import finding, not a claim about voice quality. No calls, SMS, CRM connections, desktop app or AI features were tested. The Contacts screen had no export button; Analytics offered report exports by email, whose contents we did not inspect. Before migrating, request and verify a route for exporting contacts as well as call reports. An import working does not prove you can retrieve the same records later. Read my hands-on review →

5. KrispCall — Numbers in many countries at a budget seat price

Virtual numbers across 100+ countries with a shared dashboard, dialer and CRM hooks, priced per user.

My take: This is a candidate when the need is virtual numbers with a shared dashboard and CRM hooks. The current Starter rule, read 7 October 2026, is $12 per user per month billed annually or $15 monthly, for at most five users. Advance is $32 annually or $40 monthly for up to fifty; Max is $48 or $60 without a member limit. Avoid reading the low Starter rate as an offer for a larger team. The dossier now records included call and SMS allowances, so saying every minute is charged on top of every seat would be misleading. It also records a separate balance for additional usage and numbers. Ask the vendor to identify which of your routes use the allowance and which draw credit; use a busy month, not only an average month. US business texting has registration costs in our dossier and should be quoted separately if it matters to your workflow. We have no hands-on calling result for this comparison. Treat dashboard and dialer availability as dossier facts and call quality, migration and export completeness as questions for your pilot. Read our full KrispCall review →

6. Calilio — Startups that want a simple cloud phone system

Cloud phone system with international numbers and call menus, priced per user.

My take: Start by deciding whether Standard has the controls you need. Its rule, read 10 October 2026, is $12 per user per month billed annually or $15 monthly, with a ten-user ceiling. Premium is $28 annually or $35 monthly. Our dossier places IVR with business hours, call transfer, power dialing, bulk SMS and live call monitoring on Premium. A small headcount therefore does not by itself justify selecting Standard. List the required call path and locate each control on the quoted plan before comparing subscription totals. The latest dossier includes monthly US and Canada call and SMS allowances; the earlier blanket description of all calls being extra is outdated. Beyond the allowance, a prepaid wallet pays for usage, and additional numbers are charged separately. Ask how the wallet is funded and what happens when it is empty, then verify that behaviour during your evaluation. The pricing page we read did not mention a shared inbox, so do not assume that a clean dashboard provides one. We have not measured delivery, voice quality or support responsiveness for this guide.

7. Vida AI — Service businesses, agencies and MSPs evaluating AI phone agents

Deploy autonomous frontline voice agents. Let AI answer calls, book appointments, and handle FAQs 24/7 without sounding robotic.

My take: Keep this in a separate buying lane: an AI phone agent is a different purchase from licences for staff to make calls. The old pilot-only description is no longer current. Our dossier reading of 17 October 2026 records a published monthly ladder for service businesses, agencies and MSPs, with usage charged separately. Consult the dated review for the plan ladder and usage definitions rather than treating our seat comparison as a total for an AI receptionist. Decide first what the agent may answer, what requires a person and how that person receives the caller's context. Ask for your intended call flow to be demonstrated, including an unsupported question and an unavailable colleague. The dossier says included usage is a dollar allowance shared across agents and does not roll over. It also records possible one-time setup charges for chosen agents and add-ons, so a platform fee alone is not the budget. We have not run a voice-agent test for this guide. No answer-quality score, booking-success rate or staffing saving is established by its presence here. Read our full Vida AI review →
