If you're running a business in France and still using legacy phone lines, the clock is ticking. Orange is phasing out the traditional copper network (RTC), making VoIP migration mandatory. In 2026, three IP PBX solutions lead the French SMB market: Yeastar P-Series, 3CX V20, and Alcatel-Lucent OXO Connect. Each has clear strengths — this guide helps you choose based on your company size, industry, and budget.

Key takeaway: There is no single "best" solution. The right choice depends on your team size, industry (healthcare, hospitality, retail, professional services), integration needs (CRM, nurse call, CCTV), and whether you have internal IT support. This guide gives you the facts to decide.

Important: 3CX Pricing and Licensing Changes in 2026

3CX has introduced several changes that directly impact budgeting. The Enterprise Edition price increased by approximately 15% in November 2025. Smaller license pricing was further adjusted in January 2026. Legacy free 4SC licenses are limited to 2 simultaneous calls in 2026. A fair-use policy on extensions (maximum 5× the license size) will be enforced starting April 1, 2026 at the earliest. These changes are worth factoring into your total cost of ownership calculations.

Healthcare & Nursing Homes (EHPAD)

French nursing homes (EHPADs) have unique requirements: DECT handsets for mobile nursing staff, integration with nurse call systems (appel malade), and reliable after-hours call routing.

Yeastar offers native DECT base stations and a full REST API that allows third-party nurse call systems to push alerts directly to staff handsets. The built-in hotel management module is also relevant for senior living residences.

3CX supports DECT via third-party SIP bases (Yealink, Snom). Nurse call integration requires custom development through the Call Flow Designer or API.

Alcatel OXO benefits from ALE's legacy in French hospitals and has native connectors for certain nurse call systems. However, DECT license and handset costs are significantly higher.

4. Which Solution for Which Business?

Recommendations by Segment

SMB (5-50 users): Yeastar P-Series for the best value and easiest admin. 3CX if you have internal IT or need advanced video conferencing.

Healthcare / Nursing home (EHPAD): Yeastar or Alcatel for native DECT. Choose based on budget and nurse call integration requirements.

Professional office (law firm, accountant): 3CX or Yeastar depending on whether Microsoft 365 integration (3CX) or simplicity (Yeastar) is your priority.

Hotel / Restaurant: Yeastar Cloud Edition centralizes multi-site management. The built-in hotel module eliminates the need for third-party PMS integration for small hotels.

Retail / Multi-site: Yeastar Cloud for stores under 10 extensions. 3CX becomes competitive above 20 extensions.

Industrial / Warehouse: 3CX for large sites with heavy softphone usage. Yeastar if API integration with production systems is critical.

Local government / Public sector: Alcatel-Lucent has the strongest track record. Yeastar is gaining ground on value for money.

5. FAQ

Is the copper network shutdown in France definitive?

Yes. Orange has planned the complete phase-out of the traditional copper network (RTC/PSTN). All businesses must migrate to VoIP. A SIP trunk replaces your analog lines. Your integrator handles the number porting process.

Can I keep my existing phone numbers?

Yes. Number portability is guaranteed by French telecommunications regulation. The process typically takes 7-14 business days.

Is 3CX safe after the 2023 supply chain attack?

3CX suffered a supply chain compromise in March 2023 (desktop app trojanized via a third-party dependency). The company completely re-architected its platform for V20 with a strong security focus. 3CX has stated it does not foresee major architectural changes for at least 3 years. The incident was a catalyst for significantly improved security.

Can the phone system integrate with CCTV and alarm?

Yes. Through APIs, it's possible to link VoIP (call detection, intercom) with IP video surveillance (Hikvision, Dahua, Axis) and alarm systems. This is especially valuable for nursing homes, retail, and industrial sites that want centralized management.

How to choose a telecom integrator in southern France?

Check vendor certification (Yeastar Certified Partner, 3CX Platinum, ALE Business Partner), ask for references in your industry, verify the maintenance SLA (guaranteed response time), and prioritize a multi-service integrator (telecom + CCTV + alarm + network) to avoid dealing with 4 separate contractors. A local integrator based in the PACA region can intervene within hours, unlike a national player who may send a subcontractor days later.
