VoWiFi Training Course

Tonex just lunched the first VoWiFi training course covering all aspects of VoWiFi, Voice over WiFi with EPC core, IMS, SIP, Diameter: http://www.tonex.com/training-courses/vowifi-training. Learn how WiFi carries voice and other real-time services. For complete course details visit VoWiFi Training page here.

In the VoWiFi training, participants will learn about WiFi, VoWiFi concepts, VoWiFi architecture with IMS/SIP, interworking with LTE/EPC, VoWiFi protocols and interfaces and VoWiFi procedures and security. Principles of IMS, SIP, Diameter and new 3GPP EPS interfaces supporting interworking with VoWiFi.

Learn how as a service-provider to combine Wi-Fi fully into your overall voice, SMS, MMS and other real time service-offers. WiFi interworking with LTE/EPS and IMS will deliver voice, messaging and other media service serviceson. Carrier Wi-Fi capabilities allows service-providers to offer seamless, real-time  quality media services, high-quality and seamless multimedia services to subscribers, on Wi-Fi, alongside their other broadband and mobile offering.

TONEX VoWiFi will provide  knowledge and skills to enable Service-Providers to include IMS and SIP-enabled Voice and media services over Wi-Fi, interworking with 3G/4G Mobile.

WiFi networks can now deliver mobile voice, SMS, MMS and other media services with better QoS and lower latency. VoWiFi is now a globally interoperable and exciting IP-based voice, SMS, MMS, and video calling solution for WiFi with EPS and IMS interowkring, known as VoWiFi, which also enables development of new innovative communication services.
Traditional over-the-top (OTT) communication services solutions, such as Skype and FaceTime, introduced n VoIP, video-calling and messaging services with little or no QoS/QoE measures in place, no handover mechanism to the 3GPP network and no guaranteed emergency support or security and safety. Traditional OTT based services are still in need of mobile-broadband coverage to complement quality, security and flexibility in their communication services.
