Signalling gateways
The Leissner Signalling Gateway may be implemented as an integral part of a large Softswitch deployment, or installed as a separate unit providing signalling conversions between various types of TDM- and IP-based telephony systems.
Whether you are looking for a C7-gateway for your OpenSER implementation or and ISDN to C7 conversion for extending a PRI-based platform, our signalling gateway provides a reliable and cost-efficient alternative.
Our system is truly flexible in its functionalities and potential fields of applications. It provides any-to-any signalling conversions, with overlap-signalling supported in all protocols. As it operates a subset of the Leissner Softswitch routing engine, numerous features for number alterations, signalling translations and manipulations are also available trough the system. Typical areas of applications of the Leissner Signalling Gateway are:
- SS7 Gateway - providing full SS7/C7 signalling capabilities to any VoIP platform or network. Or, enabling SIP-Interconnect and/or SIP-Trunking capabilities to legacy telephony platforms/networks.
- ISDN - SS7 protocol conversion, enabling PRI-based telecom systems to scale beyond the in-built boundaries of ordinary ISDN connections.
- Media Gateway Controller - Providing call control of any 3:rd party Media Gateway by means of MGCP, H248/MEGACO or SIP.
- INAP Gateway - enabling pure VoIP systems to connect to legacy IN systems and access services such as ACQ, Access Screening, Intelligent Routing, etc.
Any-to-any signalling conversion
The flexibility of the system is largely a result of its modular software architecture. The entire system is build around a high-efficient core switching module. Supported protocols, such as SIP, MGCP, SIGTRAN, etc, are implemented as separate system modules, and these interact with the core module through well-specified internal API:s. The Core Module itself is completely protocol independent and capable of shuffling signalling information in-between any two interconnected protocol system units.
