Read the Press Release


Dialogic can show you how to gain your competitive edge and shed yourself of the limitations of your end-of-life TDM or softswitch technology. Transform your switching infrastructure into a powerful service delivery machine with the ControlSwitch System softswitch.

The ControlSwitch System is an open, carrier class platform that delivers the features service providers demand like
  • Multi-protocol connectivity
  • Distributed architecture and true geographic redundancy
  • Centralized management and policy based routing
  • Interoperability with other vendors’ media gateway platforms
  • Extensive reporting and troubleshooting tools
  • Cost-effective scalability without the need for a forklift upgrade

Combine the intelligent call control features of the ControlSwitch System with the industry leading I-Gate® 4000 PRO and EDGE Media Gateways and you can start taking advantage of significant bandwidth savings, in some cases up to 93%, as you modernize your global IP network.

Transform Your Legacy Switching Infrastructure

Service providers around the globe have deployed the ControlSwitch System to replace their aging and end-of-life legacy softswitch or TDM switching infrastructure. The ControlSwitch System Class 4 softswitch scales from a few thousand ports to networks with over one million ports expanding as your demand grows and eliminating the concern of having to undergo costly forklift upgrades like some other vendor approaches. And since it is an open softswitch solution, the ControlSwitch System is field proven to work with an array of other vendors' media gateways such as from Cisco or AudioCodes to help operators leverage their existing legacy investment.

The ControlSwitch System includes Diameter protocol support for charging and postpaid applications as well as support for CAMEL protocol based services such as mobile number portability. The operationally friendly platform makes it easier to centrally manage multiple ControlSwitch System instances across the globe and reduces the time and effort to update even the most complex routing tables. Reduced footprint configurations for the ControlSwitch System gives service providers with more modest initial traffic requirements, a future-ready, cost-effective, carrier-class switching platform with advanced features to help differentiate their VoIP offerings.

Service providers have the flexibility to architect their network with true geographic diversity. That means high availability and disaster recovery as well as increased operational efficiency since you can manage your Class 4 infrastructure as a single entity.

Migrate to IMS/VoLTE With Confidence

Service providers needing best-in-class connectivity to both IP and TDM networks can deploy the ControlSwitch System to act as both the Media Gateway Control Function (MGCF) and Breakout Gateway Control Function (BGCF) in next generation IMS/VoLTE networks. I-Gate 4000 PRO and EDGE Media Gateways provide the bearer plane handling and BorderNet™ Session Border Controllers can be integrated operationally with the ControlSwitch System to provide IP-to-IP connectivity for Interconnection Border Control Function (IBCF) applications. The ControlSwitch System is part of Dialogic's comprehensive portfolio of IMS transformation solutions to help you take your network to the next level.

Case Study

Technology Brief

White Paper

  • As the industry moves more towards full-scale IP networks, the issue of interconnecting diverse networks and different service providers - each with its own IP network(s) - becomes more important to resolve in order to support the seamless delivery of next generation services. There will be concerns for security and end-to-end quality of service (QoS) to be addressed to make sure the different “moving parts” that make up these services are delivered to the customer in the expected manner.  It will be important to set up the mechanism by which all the participants in the service delivery supply chain are compensated for the value they provide to the overall end-to-end service.

    The GSMA IP eXchange (IPX) provides a visionary approach to the challenges fixed and mobile service providers have with interworking IP-based services and networks. It provides multiple, service-aware connectivity models that provide QoS as well as cost efficient, optimal routing of IP traffic. The same platform can be extended to bridge the gap between IP and legacy TDM networks.
