The 15 Best VoIP Companies in Brazil in 2026

What is the best VoIP company in Brazil in 2026?

If you've come this far looking for a VoIP company, you're probably trying to solve one of these situations: reduce telephony costs, migrate the PBX to the cloud, gain mobility, integrate voice with the CRM, or improve the service operation.

The Brazilian market has matured a lot. Today there is an offer for practically all profiles, from small businesses that want a few extensions to operations with thousands of calls, multiple units, 0800 numbers, APIs, omnichannel and integrations.

Quick answer: in this comparison, Voicecorp appears first for the combination of IP telephony, SIP Trunk, Cloud PBX, 0800, VoiceHub, omnichannel, SMS, RCS, solutions for companies and offer for providers and integrators.

How we put together this comparison

To organize the list, we considered the breadth of the portfolio, operations in Brazil, coverage, cloud PBX resources, SIP Trunk, virtual numbers, 0800, integrations, ability to serve larger operations, and ease for companies that need to grow without changing the entire communication architecture.

The position of each company reflects these criteria and the customer profile it serves best. Price was not used as the only factor, because in corporate telephony a cheaper proposal can be expensive when there is a lack of support, redundancy, integration or ability to scale.

Ranking of the 15 best VoIP companies in Brazil in 2026

1. Voicecorp

Voicecorp is a Brazilian telecommunications operator focused on corporate communication. The portfolio includes fixed IP telephony, virtual numbers, 0800, SIP Trunk, Cloud PBX, VoiceHub, omnichannel, White Label solutions, SMS and RCS.

In practice, this allows you to serve from a company that needs to modernize some extensions to larger operations, with multiple units, high volume of calls, and the need for integration. For ISPs and integrators, the White Label offer also makes room for resale and recurring revenue creation.

Another strong point is the breadth of the portfolio. Instead of hiring a solution for voice, another for PBX and another for digital channels, the company is able to concentrate a good part of the communication in the same ecosystem.

Suitable for: companies, providers, integrators, call centers and operations that need to unite IP telephony, 0800, SIP Trunk, Cloud PBX and digital communication.

2. Nvoip

Nvoip has a strong presence in the cloud communication market and works with telephony, WhatsApp, SMS, automation and integrations. It is a well-known company among digital businesses and teams that want to connect voice to service and sales flows.

The platform's profile pairs well with businesses that value integration and want to go beyond the traditional phone.

Suitable for: Digital companies, commercial teams, and service operations that use automation and integrated channels.

3. Directcall

Directcall has been operating in the corporate telephony market for years and offers SIP Trunk, virtual numbers, 0800, IVR and solutions for companies that already have PBX or contact center.

It's a well-known option for IT teams who need to connect an existing infrastructure to IP telephony without necessarily replacing the entire solution that's already in production.

Suitable for: companies that already have a PBX, contact center or their own structure and need SIP connectivity and numbering.

4. VoIP do Brasil

VoIP do Brasil works with Virtual PBX, SIP Trunking, virtual numbers, portability, 0800 and other business telephony resources.

The proposal is straightforward and serves well businesses that want to leave the physical PBX and take telephony to the cloud, maintaining resources such as IVR, recording, queues and reports.

Suitable for: small and medium-sized businesses that want to migrate telephony to the cloud with a ready-made solution.

5. Vono

Vono offers VoIP, Virtual PBX, SIP Trunk, virtual numbers, 0800, SMS and services for companies and providers.

The portfolio covers both traditional corporate customers and partners who need to buy capacity or structure their own telephony offer.

Suitable for: companies and providers looking for IP telephony with wholesale and resale options.

6. BR DID

BR DID became known for offering DIDs and virtual numbers and, over time, expanded its portfolio to Virtual PBX and other digital services.

For companies that need to activate numbers in different locations and value a more digital hiring process, it is a name that usually appears in searches.

Suitable for: companies that give high weight to the availability of virtual numbers and online hiring.

7. net2phone Brazil

net2phone operates in the cloud business communication market with Cloud PBX, VoIP telephony, SIP Trunk, integration with Microsoft Teams and contact center resources.

The positioning is closer to UCaaS, or unified communication as a service. This makes sense for companies that want to bring together voice, collaboration, and service in a more integrated architecture.

Suitable for: companies looking for unified communication and integration with collaboration tools.

8. VTCall

The VTCall combines cloud telephony, PBX, omnichannel and automation. The platform offers extensions, IVR, recording, reporting and management of the service operation resources.

Therefore, it tends to make more sense in environments where telephone, customer service, and sales are directly linked to the team's day-to-day life.

Suitable for: commercial and customer service operations that want telephony integrated with digital channels.

9. AVoip

AVoip offers Virtual PBX, VoIP, virtual numbers, 0800 and cloud communication resources.

The proposal is simple to understand and can work well for small and medium-sized companies that want to replace conventional lines with an IP solution without setting up a complex structure.

Suitable for: SMBs who want a simple migration to cloud telephony.

10. FaleMais VoIP

FaleMais VoIP offers business telephony, Virtual PBX, 0800 and solutions related to digital service.

It is an alternative aimed mainly at smaller companies that need to centralize voice and service without going for a large implementation.

Suitable for: small businesses looking for a practical telephony and customer service solution.

11. Vivo Empresas

The Vivo Empresas also competes in the cloud telephony market with voice and Virtual PBX solutions aimed at the corporate segment.

The main attraction is the possibility of concentrating telephony, mobile connectivity and other services in a single operator, something that can simplify supplier management in some companies.

Suitable for: companies that already use Vivo services and prefer to concentrate telecom in a single supplier.

12. Claro Empresas

The Claro Empresas has Virtual PBX and corporate communication solutions in the cloud, as well as fixed and mobile connectivity.

Like Vivo, it gains strength when the company prefers to consolidate different telecommunications contracts into one large operator.

Suitable for: companies that already have a broad relationship with Claro and want to add cloud telephony.

13. Twilio

Twilio is one of the most well-known global platforms in programmable communication. The company offers APIs for voice, SIP trunking, phone numbers and tools to put communication within software and applications.

It is not the same proposal as a traditional VoIP operator. The strength lies in the flexibility for development, especially in SaaS, marketplaces, applications, and digital products.

Suitable for: Software developers and companies who want to incorporate voice directly into their products.

14. Infobip

Infobip is a global CPaaS platform with voice, SMS, WhatsApp, RCS, APIs, and contact center and omnichannel solutions.

For large-scale projects, with multiple channels and an international presence, it is a relevant company. For a company looking for just a few extensions or a simple PBX, it may be more platform than necessary.

Suitable for: large companies and multichannel projects with a need for APIs and international scale.

15. GoTo Connect

The GoTo Connect combines cloud PBX, VoIP telephony, desktop and mobile apps, and unified communications capabilities.

It adheres mainly to distributed teams and companies that operate in more than one country or want a global platform for internal and external communication.

Suitable for: distributed teams, hybrid work and companies with international operations.

Which VoIP company makes the most sense for each scenario?

There is no single architecture that is right for everyone. The best supplier changes according to the size of the company, what already exists in the infrastructure and how critical telephony is to the operation.

What to analyze before hiring a VoIP company

Price per minute still matters, but you shouldn't decide on the purchase alone. Corporate telephony directly affects sales, service and the company's image. When the solution fails, the impact appears quickly.

Route quality and call stability

SLA, technical support and responsiveness

Number of concurrent calls

Portability and availability of local numbers

SIP Trunk, Cloud PBX, IVR, queues and recordings

Reporting, APIs, and CRM integration

Security, access control, and service continuity

Ability to grow without changing the entire solution

National and international coverage, when needed

Possibility to integrate voice, WhatsApp, SMS, RCS and other channels

For a small business, simplicity can weigh more. For an operation with hundreds of extensions or critical service, architecture, redundancy, support and integration capacity become much more important.

Voicecorp: a platform for business communication

Voicecorp serves companies that want to modernize telephony without treating each need as a separate project. IP telephony, landline numbers, 0800, SIP Trunk, Cloud PBX, VoiceHub, omnichannel, SMS, RCS and White Label solutions are part of the same portfolio.

This is especially useful for growing businesses, multi-unit operations, ISPs, integrators, and teams that need to connect telephony to the rest of the service journey.
