Voice over Long-Term Evolution (VoLTE)

Voice over LTE (VoLTE) empowers 4G LTE operators to offer rich voice, video and messaging services as a core offering.

Transformation of circuit-switched networks that carry voice to all-IP 4G LTE networks will realize cost advantages and recover inefficient spectrum for additional data capacity. With 4G, LTE operators can leverage service ubiquity, access mobility, global interoperability and universal user identity of phone number to enable continued monetization of voice and messaging. These fundamental values help mobile operators compete against the OTT web-based service providers and establish an environment where new user experiences can be offered to any generation of mobile devices.

Voice over LTE provides drastic cost savings and enables new services such as Video calling, multi device, single number and multimedia sharing services across mobile broadband devices. Mitel's VoLTE solution is based on our innovative TAS product which provides service parity and supports 3GPP MMTEL, MAP and ANSI-41 services. The solution offers unique differentiators such as integrated IM-SSF to offer seamless service experience and mobility functions to enable seamless mobility across LTE, 2G, 3G and Wi-Fi networks.
