Voice over LTE (VoLTE) and Voice over WiFi (VoWiFi)



Our VoLTE solution, provided in conjunction with our EPC, enables customers to maximize the power of LTE services for both voice and data. It is an IP Multimedia Subsystem (IMS) solution for Voice and Video over LTE (VoLTE) that implements the Call Session Control Function (CSCF) components (P-CSCF, I-CSCF, and S-CSCF), Session Border Controller (SBC) and Telecommunication Application Server (TAS) functions. By combining it with our trusted and untrusted WiFi access solution, customers can implement a highly efficient VoWiFi solution.
