The basics: Voice over IP (also known as VoIP, IP trunking or SIP trunking) places voice calls over data networks instead of traditional phone lines. This enables cost savings, improves management capabilities, and provides reliability and security. It is also the foundation for supporting unified communications (UC) applications.

Global coverage: Verizon VoIP provides or ports telephone numbers to your business  for inbound and outbound calling. We provide a full in-country  public switched telephone network (PSTN) replacement* (including access to emergency services) in almost 40 countries across the Americas, EMEA and APAC.

Subject to availability and local regulations.

One network for voice and data: Our VoIP portfolio of products gives you the ease and efficiency of one converged network for both voice and data services.

Self-service portal: Verizon continues to invest in the development of our VoIP-on-demand customer self-service capabilities. The portal helps you pull near real-time reporting on service performance and usage, order new service extensions, change configurations, or take training on how to best use the products.

Flexible, scalable: You can grow your system to support remote locations, since the service is scalable and interchangeable with other VoIP services. No need to update expensive PBX equipment or support on-premises solutions.

Voice communications: Harnesses the power of Verizon’s VoIP global network to give your organization cost-effective, flexible, secure and reliable voice communication to customers, partners and those outside your business.

Any size business: Our VoIP services deliver enterprise-class features to large and small customers alike with flexible choices to deploy the solution that’s right for your business.

Productivity-enhancing solutions: Our VoIP packages also deliver the administrative and end-user productivity-enhancing applications to help telecom managers easily operate and control their networks.

Packaged solution for small businesses: Smaller companies may benefit from our packaged solution of our VoIP, internet access and on-customer-premises managed hardware. 

Use cases: VoIP is a core modern communications technology that solves problems for a variety of business types. It can help transition a large complex company from legacy phone systems to modern communications platforms in a controlled migration. It can be used to quickly upgrade and replace the phone system of a small company moving to a cloud environment. It helps you save money and improve security and reliability while future-proofing your telecom investment.
