VoIP Trunk Gateway SMG-2016 with IP-PBX support

  • Quad-Core ARMv7 Marvell Armada-XP Processor 
  • up to 16 Е1 flows (RJ-48) 
  • up to 768 VoIP channels 
  • IP-PBX for 3 000 SIP users with VAS and LAES support 
  • support of 2 HDD SATA 2.5" 
  • reliability of operator’s class 
  • scalable 1U platform 
Hybrid SMG-2016 platform can be used as a trunk gateway for conjugating signal flows and media flows of TDM and VoIP networks, IP-PBX with supporting VAS and LAES functions as well as be used as a universal solution for building new-generation research communication networks. Wide functionality, strict compliance with the standards and high reliability of the operator’s class help to handle a greater number of tasks coming up with the operators and service providers on the basis of SMG-2016. 


SMG-2016 provides a possibility of uniform distribution of investments for scaling within the entire period of project implementation. The gateway supports up to 16 Е1 flows (CCS7 (common channel signalling), PRI) and up to 768 VoIP channels. 

Operator’s class reliability 

The up-to-date processor Quad-Core ARMv7 Marvell Armada-XP, uniform load distribution between sub-modules, backed-up power supplies, possibility of joining two platforms SMG-2016 into a cluster as well as the use of the cutting-edge technologies based on parallel calculations ensure high level of SMG-2016 platform fail-safe behaviour with automatic switchover to a standby element in case of failure of any system sub-module as well as power module. 

Functional compatibility 

Strict conformity to the requirements of up-to-date protocols, recommendations and standards ensure 100% functional compatibility of SMG-2016 with different equipment: digital АТS, IP-PBX, Softswitches, VoIP gateways, SIP telephones, program SIP clients, etc. 

Transcoding media flows 

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

IP-PBX with VAS and LAES support 

Additional options for SMG-2016 gateway allow using it as a full-function IP-PBX up to 3, 000 SIP subscribers with supporting a wide set of VAS, as well as full compliance with regulatory documents according to LAES. The IP-PBX ECSS-10 program module is intended for fast deployment of VoIP communications node with minimal capital expenses (CAPEX). Availability of all types of certificates for a family of products ECSS-10 makes it possible to use IP-PBX ECSS-10 on the basis of trunk gateway SMG-2016 as an PBX of any level with subsequent acceptance for operation by the authorities of Russia's Communications Oversight Agency and Federal Security Service of Russia. 

Intellectual protection of IP networks 

The intellectual protection against unauthorized external connections of SIP subscribers (fail2ban, iptables, white/blacklists, etc.) has been implemented in trunk gateway SMG-2016. In order to provide additional protection when connecting to public IP networks, a compatibility with the session border controllers (e.g., SBC-2000) performing the functions of internetwork screens for VoIP networks. 

RADIUS routing 

Intellectual call routing based on the billing system responses according to RADIUS protocol will help build flexible rules for calls processing.
