La mejor centralita virtual para pequeña empresa en 2026

The best virtual PBX for small businesses in 2026

Q: How much does a virtual PBX cost for a small business?

For a company with 5 to 20 people in Spain, the typical price can range between €15 and €35/user/month. It's worth checking whether the plan includes integrations, technical support, and initial setup, since some providers charge these separately.

Q: Do I need hardware to install a virtual PBX?

No. A virtual PBX runs in the cloud, so it doesn't require specific physical infrastructure. You can use it through an app installed on a phone or computer, though it can also integrate with IP phones.

Q: How quickly can I have the PBX up and running?

With Glofera Connect, the PBX can be up and running within roughly two to five business days. The team handles setup, extensions, forwarding rules, integrations, and any necessary training.

Q: Can I keep my business number when switching PBX providers?

Yes. You can keep your number through the number portability process regulated in Spain. Glofera manages the entire process to minimize any possible service interruption.

Q: What's the difference between a virtual PBX and a physical PBX?

A physical PBX requires hardware, installation, and maintenance on the company's premises. A virtual PBX runs in the cloud and lets you make and receive calls from different devices and locations, without relying on your own physical infrastructure.

The question “what’s the best virtual PBX” doesn’t have a single answer. The best option for a 50-agent contact center isn’t the best option for a 3-person dental clinic. This article gives you the real criteria for choosing — and an honest comparison of the most common options in Spain.

What “best” means for a small business

Fair price: not paying for features you’ll never use.
Easy to get started: no need for an in-house technician to set it up.
Spanish-language support: when something breaks, you need to talk to someone who understands you.
No long-term commitment: flexibility to switch if it isn’t working.
Integrations with your current software: CRM, ERP, management tools.

Why a prior consultation changes everything

The most common mistake when choosing a PBX is signing up before you know what you need. Most providers sell you the product, you configure it yourself, and if there’s a problem you open a ticket. Glofera does exactly the opposite: it first analyzes how your company works, what your call flows look like, what needs to integrate with your CRM, and then recommends the right solution. No one else in the Spanish market does this. And it’s free.

Sectors where Glofera Connect stands out

Accounting and consulting firms: clients calling during peak load moments, need for extensions and recording.
Dental clinics: after-hours calls, smart forwarding, missed appointment notifications.
Real estate agencies: every call is a potential lead, per-agent statistics are essential.
Auto repair shops: the mechanic can’t pick up the phone while working; the system handles it.
Law firms: professional image, confidentiality, never missing a call.

What to avoid when choosing a virtual PBX

Plans with high minimum user counts: if you have 3 employees, don’t pay for 10.
Providers with no Spanish-language phone support: tickets don’t solve urgent issues.
Contracts with long commitments: the market changes; you need to be able to change too.
Self-managed setup if you don’t have an in-house technical lead.
