Hybrid platform SMG-3016 is used as a trunk gateway for interfacing of signal and media streams of TDM and VoIP networks. The gateway also might be used as an IP PBX with value added services (VAS) support and a multipurpose solution for infocommunication new generation networks (NGN). The wide function set, strict compliance with requirements and standards, as well as carrier-grade reliability allow service providers and carriers to solve most part of their objectives on the basis of SMG-3016.

Scalability
SMG-3016 is a beneficial investment in the future of your project due to its scalability. The gateway supports up to 16 E1 streams (SS7, PRI, V5.2) and up to 768 VoIP channels.

IP PBX with VAS support
Additional options for SMG-3016 gateway allow using it as a full-featured IP PBX for up to 3,000 SIP subscribers with support for a wide range of value added services. A programmable IP PBX module ECSS-10 is designed for fast deployment of a VoIP node with a minimum of capital expenses (CAPEX). ECSS-10 and SMG-3016 might be used as a PBX of any level.

Carrier-grade reliability
Uniform load distribution between submodules, redundant power supplies, as well as the use of modern technologies based on parallel computing provide a high level of fault tolerance of the SMG-3016 trunk gateway with automatic switching to a backup submodule in the event of any system submodule failure or the power source.

Functional compatibility
The strict compliance with requirements of up-to-date protocols, recommendations and standards provides functional compatibility of SMG-3016 with a variety of equipment: digital PBX, IP PBX, Softswitch, VoIP gateways, SIP phones, software SIP clients, etc.

Media streams transcoding
The hardware transcoding helps to negotiate media streams with different VoIP codecs which are used in up-to-date networks.

Intellectual protection of IP networks
The intellectual protection against unauthorized external SIP subscribers connection and connections via http/https/telnet/ssh is realized on the SMG-3016 (Dynamic Firewall, Static Firewall, black and white lists of IP addresses and subnetworks, etc.). For additional defense, SMG-3016 is compatible with session border controllers (e.g. SBC-3000) that are used as a firewall for VoIP networks.

RADIUS routing
Intellectual call routing based on billing system responses via the RADIUS protocol allows you to create flexible methods of call processing.
