The EdgeMarc is a flexible, easy-to-use session border controller that provides many critical networking functions for IP-based voice and data.

This guide describes the EdgeMarc VoIP Operating System (VOS), and is intended for network installers and system administrators.

This guide assumes that you have already installed and cabled your device according to the instructions in the hardware installation guide that came with your EdgeMarc.

The sections in this guide represent configuration tasks in the EdgeMarc GUI Configuration Menu. Your Configuration Menu may vary, depending on your EdgeMarc model and features included with your software version.

Before you Begin

Before you use the information in this guide, make sure that you are connected to the device through a supported web browser.

Additional information about the features provided by VOS can be found in our extensive knowledge base: https://sonusnetworks.secure.force.com/KB/. 

Understanding the EdgeMarc VoIP Operating System

Ribbon Communications EdgeMarc VoIP Operating System (VOS) provides award-winning features for converged networking environments. These features enable the EdgeMarc to act as an enterprise session border controller and demarcation point for managed services.

VOS supports all EdgeMarc session border controller models from Ribbon. For a current list of available models, refer to the Ribbon website.

Using the VOS web-based user interface, you can configure settings that allow the EdgeMarc to provide the following:

  • Network Address Translation (NAT) and firewall traversal using a VoIP Application Layer Gateway (ALG) supporting SIP and H.323
  • Support for a configurable amount of concurrent VoIP calls
  • Enterprise LAN protection using a stateful packet inspection (SPI) firewall for voice and data traffic
  • NAT and Port Address Translation (PAT) for voice and data
  • Static IP routing
  • Traffic Management
    • Prioritization
    • Classification
    • Queuing
    • Type of Service (TOS) bit setting
    • Call admission control for voice
  • Voice call quality monitoring and testing
  • Integrated test tools to facilitate problem isolation
  • DHCP server options for enterprise computers and IP phones
  • FTP and TFTP options for IP phone images
  • SNMP and SYSLOG for logging to Network Management Systems

Deploying the EdgeMarc

Your EdgeMarc configuration is based on your deployment scenario, VoIP topology, and presence of other networking equipment such as firewalls or DHCP servers.

Although the EdgeMarc can be installed in many different VoIP topologies, this document describes how to configure the EdgeMarc to support two basic deployment scenarios:

Deploying the EdgeMarc in IP Centrex Networks

A typical IP Centrex deployment may be comprised of the following:

  • The WAN link from the service provider is terminated by an external router, xDSL, or cable modem.
  • The EdgeMarc is connected directly to the WAN termination device and to the enterprise LAN (typically a layer 2 switch).
  • VoIP signaling is performed in the service provider network via a softswitch.
  • The EdgeMarc acts as a proxy for the voice devices installed in the enterprise LAN.
  • A single public IP address is used as proxy for the IP phones. It is also used to route calls to multiple PCs on the LAN.

Deploying the EdgeMarc in Station Side IP PBX Networks

Most private enterprise VoIP networks use an IP PBX at the corporate headquarters to provide voice switching among headquarters, branch offices, and the PSTN. The EdgeMarc is used in these environments to securely connect branch office employees to the IP PBX installed in the corporate headquarters location. A station-side IP PBX deployment may be comprised of the following:

  • The branch office is connected to the corporate network using VPNs or private T1 links terminated by a WAN router.
  • The EdgeMarc is connected directly to the WAN router and to the enterprise Ethernet LAN (typically a layer 2 switch).
  • The IP PBX in the corporate headquarters location performs VoIP signaling.
  • The EdgeMarc acts as a proxy for the voice devices installed at the branch office.

Accessing the Web-Based GUI Interface

The EdgeMarc VOS user interface is accessible through a web browser. The VOS interface includes intuitive menus and options for:

  • System administration
  • Network configuration and management
  • User management
  • Security
  • VoIP ALG
  • VPN
