The Best Global VoIP Service Providers

The Best Global VoIP Service Providers

Global enterprises are increasingly turning to Voice over Internet Protocol (VoIP) to enhance their contact center’s phone service infrastructure. 

Unlike traditional phone lines, communications sent over the internet provide tons of benefits and opportunities for businesses, including better sound quality, decreased costs, more scalability, and phone number management control. 

There are several global VoIP service providers to choose from, and comparing them can require a lot of time– so we did the work for you. Compare the list of the best global VoIP providers to evaluate which is right for your contact centers. 

Why Use VoIP Numbers?

Voice over IP numbers are advantageous for your contact center voice stack because they provide:

  1. A local presence for you to expand into new markets, without the need for physical offices or on-site infrastructure. 
  2. Lower monthly costs compared to traditional phone systems that reduce business expenses and lower total cost of ownership. 
  3. High voice quality that delivers clear and reliable communications. 
  4. Scalability that allows you to grow or reduce your virtual phone lines at your leisure. 
  5. Accessibility to provide an agile and flexible way to work and connect with customers. 

Along with the benefits listed above, you have access to various types of VoIP phone numbers to suit your needs, including…

  • Direct Inward Dialing (DID) numbers are assigned to a specific line, allowing customers to directly reach their intended destination without requiring an extension, or going through a menu or call queue. 
  • PSTN Replacement (TrueLocal) numbers allow two-way communication and guaranteed local caller ID (CLI) for calls made to another country. 
  • International Toll-Free Service (ITFS) numbers enable customers to reach your contact center without incurring any charges, encouraging engagement from different countries. 
  • Universal International Freephone Numbers (UIFN) are similar to international toll-free numbers but can be dialed from multiple countries, facilitating international customer reach using only one number. 
  • Mobile numbers support SMS and voice communication, offering flexibility and convenience for those customers who prefer to interact on their mobile devices. 
  • National (also known as Non-Geographic) numbers provide a single point of contact for customers in a specific country, enhancing local presence and accessibility for domestic callers. 
  • Full PSTN Replacement numbers offer a comprehensive in-country solution by providing local numbers and emergency services.
