IMS for VoLTE and VoWiFi

IP Multimedia Subsystem

IP Multimedia Subsystem (IMS) is a session control architecture composed of specialized network elements linked together through open interfaces.

IMS has been mandated as the control architecture for Voice over LTE (VoLTE) networks, and additionally, offers and effective approach to managing carrier Voice over WiFi (VoWiFi) traffic.

The benefits of an IMS network include:

Convergence of mobile and fixed access networks

Support for multimedia services

Ability to construct multi-vendor networks

Dialogic’s field-proven IMS network elements and world class professional services enable both mobile and fixed operators to cost-effectively transition core networks to IMS with minimal disruption.

Our IMS elements interoperate with third party application servers and core networks, supporting both direct-to-IMS and Next Generation-to-IMS deployment scenarios.
