VoIP Trunk Gateway SMG-2

up to 2 Е1 flows (RJ-48)
up to 64 VoIP channels

The SMG-2 platform can be used as a trunk gateway for conjugating signal flows and media flows of TDM and VoIP networks.

Optimal Solution for Digital PBX

SMG-2 gateways make a smooth transition from TDM- infrastructure to advanced VoIP - networks possible, providing full compatibility with existing Devices provides an excellent opportunity of digital PBX connection with NGN

Functional compatibility

Strict conformity to the requirements of up-to-date protocols, recommendations and standards ensure 100% functional compatibility of SMG-2 with different equipment: digital АТS, IP-PBX, Softswitches, VoIP gateways, SIP telephones, program SIP clients, etc.

RADIUS-routing

Intellectual call routing based on billing system responses according to RADIUS protocol enables to create flexible methods of call processing.

Intellectual protection of IP networks

The intellectual protection against unauthorized external connections of SIP users (fail2ban, IP-tables, white/blacklists, etc.) has been implemented in trunk gateway SMG-2.

Media Flows Transcoding

The hardware transcoding based on Media Codecs Mindspeed Technologies helps coordinate media flows with different VoIP codecs.

High Quality of Voice processing

Modern hardware platform, support of all basic audio codecs used in VoIP- networks (G.711, G.723.1, G.726, G.729), echo elimination functions, silence detector, comfort noise generator, DTMF signal reception and generation, and traffic prioritization mechanism (QoS) provide high quality of voice processing.

Interfaces

The SMG-2 trunk gateway has 2 ports RJ-48 for E1 stream connection, 1 10/100/1000Base-T LAN port (RJ-45) for connection to an IP network.
