VoIP gateway definition
VoIP gateway is a network device that converts voice and fax calls, in real-time, between the public switched telephone network (PSTN) and an IP network.
VoIP gateway bridges traditional telephone networks with IP networks, allowing for voice and multimedia communications over the internet.
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.
