VoLTE
Voice over LTE
Voice over LTE (VoLTE) based on the IMS system is widely acknowledged as the optimal voice solution for LTE network and the key to provide premium quality of voice and rich communication services in the 4G era. Major network operators, device manufacturers and chipset vendors, such as SK Telecom, LG Uplus, Verizon, AT&T, KDDI and O2, have successively launched or plan to launch their commercial VoLTE services in these years.
A superb VoLTE solution for mobile network operators, device manufacturers and chipset vendors
Juphoon VoLTE solution embraces resource-efficient voice and video codecs and advanced QoS technology, enabling superior voice and video calling service, IM and other RCS/RCS-e services. It can help operators migrate to IMS services seamlessly and device manufacturers integrate native VoLTE applications rapidly.
