New VoIP Network for Middle East Oil and Gas Ministry

In the wake of wartime destruction, a national oil and gas ministry in the Middle East needed to interconnect four remote sites with the main headquarters.

Oil Ship

As part of the rebuilding effort in the Middle East, Patton was able to provide a  secure IP-telephony system for the national oil and gas ministry.

It is interesting that two of the sites were actually ships at sea using satellite links to communicate with the ministry headquarters.

SmartNode VoIP CPE products were key elements in the complete communications solution.

In addition to the maritime mobility and satellite communication aspects, the project came with a couple additional requirements:

  • Security — Voice traffic must be secured against interception and snooping. Yest the new system must integrate with the existing software IP PBX, which does not support TLS encryption.
  • Redundancy — The ministry required redundant connections to two IP-PBXs for failover service.

The local system integrator chose Patton as the supplier for VoIP customer premise equipment (CPE) because of the unique capabilities the SmartNode VoIP product line offers.

Some noteworthy SmartNode feature/functions leveraged in the deployment are cited here below:

  • Integrated POTS interfaces: FXS for handsets, and FXO for PBX connections
  • VPN server functionality, a native SmartNode option
  • VoIP-over-VPN technology, delivering secure, encrypted voice, using IPsec strong encryption, AES and 3DES keying, and Internet Key Exchange (IKE)
  • CODECs: comprehensive selection
  • Advanced Call Routing with powerful, flexible, configurable algorithms

SmartNode VoIP CPE Devices Employed

A SmartNode Enterprise Session Border Controller (eSBC) and router was configured to function as a VPN server. Positioned at edge of the LAN the eSBC interconnects remote sites and headquarters using secure VPN tunnels running through the public Internet while routing local traffic to the dual-redundant IP PBX.

A multi-port SmartNode Analog VoIP Router (24-port FXS channel-bank) is installed at two remote sites. With satellite connections involved, low-bandwidth CODECs were configured to optimize available bandwidth. Called numbers are screened so local traffic is routed the within the ship.

An 8-port SmartNode analog VoIP gateway-router, installed at two remote sites supports up to 8 FXS or FXO telephone connections. It combines voice-over-IP (VoIP) with advanced Quality of Service (QoS).
