Usage of VoIP gateways

  • Businesses. Companies use VoIP gateways to connect their internal IP-based phone systems (like PBX systems) to the PSTN.
  • Call centers. Call centers often use VoIP gateways to handle a high volume of inbound and outbound calls efficiently. They benefit from cost savings, especially for international calls, and the ability to integrate with customer management systems.
  • Residential VoIP services. Some residential VoIP services use a gateway device to allow users to connect their traditional telephone handsets to their home internet connection.
  • Telecom providers. Telecom operators use VoIP gateways to provide services to their customers, often in conjunction with other VoIP technologies like Softswitches.
  • Remote work. For remote workers, VoIP gateways enable the integration of home or mobile telephony systems with the company's main office systems.
  • Integration with legacy equipment. In environments with legacy telephony equipment, VoIP gateways help to merge old systems with new IP-based communication technologies.
  • Education. Schools, universities, and government offices use VoIP gateways to leverage IP telephony for cost savings and enhanced features.
