This document outlines the configuration best practices for the Ribbon solution covering the EdgeMarc 300 series ATA (Analog Telephone Adaptor) when deployed with Zoom.
The Ribbon EdgeMarc 300 is a low-density analog gateway or ATA device that gives small businesses, SOHOs and branch offices with analog voice infrastructures an easy, cost-effective way to capitalize on Voice over Internet Protocol (VoIP) services. The EdgeMarc 300 Series offers a solution, providing support for integrating analog endpoints and the Public Switched Telephone Network (PSTN) and support for all Session Initiation Protocol (SIP) calls. The EdgeMarc 300 supports any-to-any connectivity between analog and SIP devices, enabling branch offices to rapidly migrate analog phones onto SIP-based networks and communicate seamlessly.
The interoperability compliance testing focuses on verifying inbound and outbound call flows between Ribbon EdgeMarc ATA & Zoom Cloud.
This guide contains the following configuration sections:
Captures the Zoom configuration.
All basic calls, along with the supplementary features like call hold, call transfer, and conference can be tested with configurations from Section A and Section B.
Advanced supplementary features can be configured on Zoom as mentioned in Supplementary Services Configuration on Zoom. These cover:
Shared Line Appearance (SLA) or Call Delegation
Shared Line Group (SLG)
It is not the goal of this guide to provide detailed configurations that will meet the requirements of every customer. Use this guide as a starting point and build the ATA configurations in consultation with network design and deployment engineers.
This is a technical document intended for telecommunications engineers with the purpose of configuring the Ribbon ATA.

This section covers the Ribbon EdgeMarc deployment topology and the Interoperability Test Lab Topology.
The following lab topology diagram shows connectivity between Zoom and Ribbon EdgeMarc ATA.
The following EdgeMarc configurations are included in this section:
Below is an image of the EdgeMarc back panel:
The following table provides details of the EdgeMarc 304 interface/port:
The current test bed setup uses the following ports:
WAN and SFP WAN ports of EdgeMarc 304 are disabled in the ATA (Analog Telephone Adapter) mode.
To configure the network interface, login to the EdgeMarc as root user and click Network.
To configure SIP UA:
Navigate to SIP UA.
Port 1 and Port 2 configuration details can be retrieved once the EM 300 ATA is added to the Zoom portal.
To add EM 300 ATA to the Zoom portal, navigate to Adding MAC address.
Assign Port 1 and Port 2 with the PSTN number as follows:
Navigate to SIP UA → Advanced and configure as shown below:
Navigate to SIP UA → SIP Proxies.
Login to Zoom Go account Web portal at https://go.zoom.us/.
This section describes the following Zoom configurations:
Select Add Desk Phone and add the MAC address of the Ribbon EdgeMarc 304.
Assign the Zoom Users as shown below and click Save.
Provision the User as follows:
Click Actions > Provision, as shown above:
As mentioned in the Zoom Desk Phone Provisioning page:
Upload the following certificates to the Ribbon EdgeMarc as follows:

This Interoperability Guide describes successful configuration covering Zoom interop with Ribbon EdgeMarc ATA.
All features and capabilities tested are detailed within this document - any limitations, notes or observations are also recorded in order to provide the reader with an accurate understanding of what has been covered, and what has not.
Configuration guidance is provided to enable the reader to replicate the same base setup - there maybe additional configuration changes required to suit the exact deployment environment.
