IPLOOK VoWiFi Solution To Enhance Competitiveness of Operators
- Wi-Fi Calling (VoWiFi) is an IMS-based voice calling technology similar to VoLTE. Based on ePDG, HSS/3GPP AAA and IMS, IPLOOK VoWiFi solution enables users to achieve high-definition voice or video calls over Wi-Fi , and seamlessly switch with VoLTE, when accessing the mobile network via Wi-Fi hotpots. Wi-Fi serves as the RAN to access the carrier’s EPC and IMS networks.
