Introduction
This document provides step-by-step instructions on installing and configuring the Zoom Phone Local
Survivability (hereafter, referred to as ZPLS) Module running on AudioCodes Mediant 800C device
with Session Border Controller (hereafter, referred to as SBC).
1.1
About the Zoom Phone Local Survivability
Zoom Phone is a cloud-based service that is dependent on IP connectivity to Zoom's datacenters.
Customers that are using the Zoom Phone solution at corporate locations are encouraged to deploy
redundant and reliable Internet connectivity with sufficient bandwidth at each corporate office as a
base requirement.
For some business locations, maintaining telephony service in the event of an outage is critical. Zoom
can offer a survivability solution of basic telephony services to provide an additional layer of
protection to ensure business continuity. An outage can be the result of an Internet service failure
at a business location, or a failure in multiple Zoom datacenters that prevent client devices from
reaching Zoom Phone components.
The Zoom Phone Local Survivability (ZPLS) module leverages the platform and Operating System (OS)
provided by the Zoom Node and is distributed as a Linux-based appliance that is spun up on an on-
premises VMware ESXi host. The ZPLS module does not affect the phone service during normal
operations. Phone clients and devices in survivable Phone Sites register to the corresponding ZPLS
module and can maintain a subset of Phone features when connectivity to Zoom Phone is lost. When
connectivity to the Zoom Phone cloud returns, clients and devices re-register back to the cloud.
During the outage, neither the administrator nor the end user is required to take any action to enable
survivability. The failover and fallback process is seamless and automatic.

About AudioCodes SBC Product Series
AudioCodes' family of SBC devices enables reliable connectivity and security between Enterprise's
and the service provider's VoIP networks.
The SBC provides perimeter defense as a way of protecting Enterprises from malicious VoIP attacks;
mediation for allowing the connection of any PBX and/or IP-PBX to any service provider; and Service
Assurance for service quality and manageability.
Designed as a cost-effective appliance, the SBC is based on field-proven VoIP and network services
with a native host processor, allowing the creation of purpose-built multiservice appliances,
providing smooth connectivity to cloud services, with integrated quality of service, SLA monitoring,
security, and manageability. The native implementation of SBC provides a host of additional
capabilities that are not possible with standalone SBC appliances such as VoIP mediation, PSTN
access survivability, and third-party value-added services applications. This enables Enterprises to
utilize the advantages of converged networks and eliminate the need for standalone appliances.
AudioCodes SBC is available as an integrated solution running on top of its field-proven Mediant
Media Gateway and Multi-Service Business Router platforms, or as a software-only solution for
deployment with third-party hardware. The SBC can be offered as a Virtualized SBC, supporting the
following platforms: Hyper-V, AWP, KVM, VMware, AWS, Azure and GCP.
