The ControlSwitch System Media Gateway Control Function

The First Step in Your IMS/VoLTE Transformation

The IP Multimedia Subsystem (IMS) MGCF is the next step in the evolution of the NGN class 4 VoIP softswitch and the first logical step in an IMS/VoLTE IP transformation strategy. It provides key functionality that supports IMS to TDM routing and interworking of media and signaling between core IMS/VoLTE, NGN VoIP and PSTN networks—the same kind of real-world environments that Communication Service Providers (CSPs) and IP Exchange (IPX) operators currently have in production today.

The ControlSwitch System MGCF is designed to make this transformation to all-IP IMS seamless and cost effective with minimal disruption to a CSP’s existing network. It also has an integrated Breakout Gateway Control Function (BGCF) that allows it to determine the most optimal way to process calls that break out of the IMS network and terminate on the PSTN.

 

Dialogic IMS/VoLTE-Ready MGCF, BGCF and MGW solutions

 CSPs can enable IP migration in their core voice networks to IMS while still maintaining connectivity with peer NGN- and TDM-based operators.

Broad Support for Global IMS Networks

The ControlSwitch System MGCF supports key VoLTE specifications, international SS7/IP signaling variants, IMS SIP, H.248 and Diameter signaling interfaces giving CSPs the ability to confidently implement their IMS/VoLTE networks. Its open architecture and ongoing conformance to evolving standards enables interoperability with IMS core platform vendors such as Mavenir Systems and Ericsson. In addition, the ControlSwitch System’s capability to leverage existing media gateways from other vendors such as Cisco, Huawei and AudioCodes helps CSPs looking to extend the life of their existing infrastructure investment.

ControlSwitch System MGCF - More Features, More Flexibility and Attractive ROI

The ControlSwitch System MGCF provides a carrier-class media and signaling gateway and interworking solution for IMS networks. Unlike some MGCF products that amount to little more than retrofitted softswitches or built on thinly supported open source IMS software, the ControlSwitch System MGCF is well suited for environments where performance, interoperability and high availability are important. The ControlSwitch System MGCF has a vast array of features that give CSPs added freedom both now and for the future:

  • Integrated BGCF and MGCF functionality on a single platform
  • Support for IMS SIP, SIP-I/T Diameter and H.248 interfaces critical for implementing VoLTE
  • Over 180 call routing parameters
  • Rapid provisioning of routing policy across all ControlSwitch System MGCF nodes
  • True geographical redundancy - check out this short video!
  • IPX IP Proxy support when deployed with Dialogic’s IBCF
  • Centralized Operation, Administration and Maintenance (OAM) system for provisioning, traces, alarms and reports
  • Mobile Number Portability and 800 number translation services
  • Wide support for external routing engines via INAP, SIP or ENUM
  • Call Detail Record (CDR) generation and seamless integration with legacy and IMS billing systems
  • Softswitch redundancy, high availability, and unparalleled scalability  with no “fork-lift” upgrade required
  • A proven track record of successful deployments in IMS networks around the world
 

 The ControlSwitch System consolidates MGCF and BGCF functionality for IMS SIP-to-TDM service interworking between IMS and legacy PSTN networks
