Telephony Application Server (TAS)

Mitel’s Telephony Application Server (TAS) has been selected by mobile operators globally as a “best-in-class” product for implementing Voice over LTE (VoLTE) and Voice over Wi-Fi (VoWi-Fi) services and has the distinction of supporting the world’s first commercial VoLTE service.

Mitel’s TAS reduces total cost of ownership and improves time to market by seamlessly integrating into the operator’s existing infrastructure, including subscriber databases, intelligent networking systems, billing systems, etc. using standard legacy interfaces. Our approach ensures mobile subscribers have a consistent user experience using next generation voice services over LTE or Wi-Fi since the TAS provides service parity with the legacy circuit-switched mobile network.

Mitel’s TAS is access agnostic and supports the range of features needed to deliver rich multimedia services such as HD voice and video calling to subscribers on LTE, Wi-Fi, Fixed or Business networks, as well as the integrated mobility features to enable service continuity to move from one access network to another.

Based on Mitel’s flagship mOne® Convergence Platform, Mitel’s TAS is a fully virtualized, highly scalable, carrier-grade solution that can be deployed on cloud-based infrastructure.
