The 3GPP ePDG provides voice calling via Wi-Fi. It is the main function enabling that an IMS deployment used for VoLTE or VoNR can be used for VoWiFi.
Neat Path Networks Wi-Fi Calling Gateway implements all the features necessary to provide VoWiFi in a secure but simplified way. It supports deployments without 3GPP AAA Server and without sending the IMS traffic via the PGW reducing the total cost of the VoWiFi architecture.
It is the perfect complement to Neat Path's Scalable Voice Core and Neat Path's Scalable Mobile Packet core
Provide Voice over Wi-Fi by adding just one new function to your network: the Wi-Fi Calling Gateway.
