Softswitch

The Leissner Softswitch is a low-cost but full-featured switching platform providing advanced class 4 transit services and extensive class 5 end-user services across any type of IP- or TDM-based infrastructure. Built on standard hardware and software components, with flexibility and cost-efficiency as guiding design principles, the Leissner system may be used in virtually any all-IP or hybrid VoIP deployment - at a fraction of the costs of a more recognized platform.

Complete VoIP switching system

The Leissner system comes with all the main building-blocks and functions of a true Softswitch; from advanced SS7 capabilities and C4 traffic management and routing, to an extensive range of subscriber services and features for both business and residential end-users. Multi-protocol support allows for MGCP, SIP and SIGTRAN/IUA to be used in parallel and fully interact with each other. End-users may even use MGCP and SIP in combined subscriptions; enabling for instance incoming ENUM-call to MGCP-devises, or bundling of SIP mobile phone clients with POTS-services on MGCP.

ISDN-emulation is a unique system feature providing fully transparent transport of Q.931 signalling and media over IP. SIP-Trunking with proven interoperability with a wide range of commercial and opensource based PBX-system, and different schemes for authentication and authorisation is available.

The system's Session Border Controller (SBC) module handles NAT-traversal, filtering and parsing of SIP- and MGCP-signalling, and setting of ToS/CoS-tags. DOS-protection, Topology Hiding, TLS-encryption and IP-address screening/filtering are other important contributions from an SBC. Interconnects arrangement based on PRI, SS7 and SIP may be used in parallel.

Comprehensive PSTN features

Call control, advanced routing schemes, white-list, carrier pre-select, number portability, subscriber services, centrex services, legal intercept, emergency calls (911/112); the Leissner switch handles all major functions of a legacy transit or local telephony switch. In fact, the system can easily turn into a full-featured TDM switch simply by adding a few TDM-interface modules to the system.

Swiss army-knife of telephony

Truly versatile and rich of features in relation to both PSTN and VoIP, Leissner offers a wide range of uses besides standard POTS-replacement type of VoIP. Whether you are looking for a SS7 gateway for an Asterisk or OpenSER system or require an ACQ implementation in your TDM-network, the Leissner switch will provide a smart and cost-efficient solution.

  • SS7/ISDN/SIP/MCCP signaling gateway.
  • SIP-based Class 4 transit services and SIP-Trunking with advanced security features.
  • IN/IN-light providing ACQ and intelligent routing to legacy or VoIP switching platforms.
  • Media-server providing IVR, Voice Mail, Fax-box.

With well structured program modules and standardized APIs for different types of system functionalities the system can be centralized to one single hardware platform, or distributed over multiple servers and locations. Adding new functions, support for third party protocol stacks or specific hardware is easily handled with adaptation modules to existing APIs. As the system use standard hardware and software components easily integrates to any open third-party VoIP-product or OSS-platform.

Robust and scalable

Field-proven hardware and software components working in a hot-standby redundancy configuration where system fail-over is managed in seconds without affecting traffic - the Leissner softswitch provides true carrier class availability and reliability.

With highly efficient core program modules system capacity is essentially hardware dependant. A minimal configuration based on one standard Intel server will handle up to 20,000 subscribers. By simply adding additional server capacity the system will scale to almost unlimited volumes.
