Installation Manual 1. Introduction 1 Introduction This document describes initial installation of AudioCodes' Mediant Cloud Edition (CE) Session Border Controller (SBC), hereafter referred to as Mediant CE. Mediant CE is a software-based product that is installed and hosted in a cloud computing environment (see note below). Mediant CE is composed of two component types: Signaling Component (SC): The SC handles all SIP signaling traffic. It also determines which Media Component (see below) handles the specific media traffic, which is based on load balancing between the Media Components. Media Components (MC): The MCs handle all media traffic, including transcoding functionality. Up to 21 MCs can be used in the deployed Mediant CE. Mediant CE provides a unified configuration and management interface, implemented by the SC. This interface provides complete control over all Mediant CE components both SC and MCs. Mediant CE supports High Availability (HA), which is implemented by: Employing two SC instances that operate in a 1+1 Active/Standby mode and that provide high availability for management and signaling traffic. Employing multiple MC instances that operate in an N+1 Active/Active mode and that provide capacity preservation for media traffic. The Stack Manager tool is provided as part of the solution. It implements complete lifecycle management of the Mediant CE stack, including initial deployment, manual and automatic scaling, healing and service teardown. The following figure provides an overview of the Mediant CE architecture. Figure 1-1: Mediant CE Architecture Version 7.2 7 Software-based SBC Series

Mediant Cloud Edition SBC Mediant CE currently supports the following cloud computing platforms: Amazon Web Services (AWS) Microsoft Azure OpenStack Note: The Mediant CE deployment on Azure and OpenStack is currently available for evaluation purposes only. Support for signaling components HA is currently not available in the Microsoft Azure environment. The scope of this document does not fully cover security aspects for deploying the product in the cloud. Security measures should be done in accordance with specific cloud security policies and recommendations. For configuring Mediant CE, refer to the Mediant Software SBC User's Manual. Installation Manual 8 Document #: LTRT-10842

Installation Manual 2. Installation Prerequisites for AWS Environment 2 Installation Prerequisites for AWS Environment Prior to installing Mediant CE in the Amazon Web Services (AWS) environment, make sure that you meet the following prerequisites: You have an AWS account. If you don't have an AWS account, you can sign up for one on Amazon's website at http://aws.amazon.com/. You have copied AudioCodes Mediant CE AMI to your account. For more information, see Section AudioCodes Mediant CE AMI on page 9. You have created an Identity and Access Management (IAM) role that enables Mediant CE to manage its network interfaces. For more information, see Section IAM Role for Mediant CE on page 10. You have created all subnets needed for Mediant CE deployment, including the Cluster subnet with a NAT gateway. For more information, see Section Network Prerequisites on page 11. 2.1 AudioCodes Mediant CE AMI AudioCodes distributes Mediant CE SBC images (AMIs) by publishing them. The images can be found under the "Public Images" section in the AWS EC2 dashboard: Figure 2-1: "Public Images" in AWS EC2 Dashboard For more information, refer to https://www.audiocodes.com/library/firmware. Prior to deploying the Mediant CE cluster, you must copy the public AMI to your account and use this copied AMI when creating the Mediant CE stack. This operation ensures that your instance of Mediant CE will continue to operate normally (including the ability to perform scale-in and scale-out operations) even if the public AMI becomes unavailable. To copy Mediant CE SBC AMI to your account: 1. Locate the public Mediant CE SBC AMI under the Public Images section in the AWS EC2 dashboard. 2. Right-click the AMI, and then from the shortcut menu, choose Copy AMI. Figure 2-2: Copy AMI Window Version 7.2 9 Software-based SBC Series

Mediant Cloud Edition SBC 3. Enter the destination region, the AMI name, and a description. 4. Click Copy AMI to complete the operation. 2.2 IAM Role for Mediant CE The following IAM role must be created prior to creating the Mediant CE stack. This role ensures that Mediant CE components can manage their network interfaces and re-assign IP addresses in case of a switchover. { "Version": "2012-10-17", "Statement": [ { "Action": [ "ec2:assignprivateipaddresses", "ec2:unassignprivateipaddresses", "ec2:associateaddress", "ec2:describeaddresses", "ec2:describenetworkinterfaceattribute", "ec2:describenetworkinterfaces", "s3:get*", "s3:list*" ], "Effect": "Allow", "Resource": "*" } ] } To create an IAM Role: 1. Open the AWS IAM console. 2. Under Policies, create a new policy as specified above. 3. Under Rules, create a new rule based on the policy created in the previous step. Installation Manual 10 Document #: LTRT-10842

Installation Manual 2. Installation Prerequisites for AWS Environment 2.3 Network Prerequisites Mediant CE uses the following subnets: Cluster Subnet: This subnet is used for internal communication between Mediant CE components and for accessing the AWS API. It must have a NAT gateway attached (for more information, see Section Cluster Subnet on page 12). The subnet is connected to both SC and MC components as the first network interface (eth0). OAM Subnet: This subnet carries management traffic (e.g., HTTP, SSH, and NTP). It is connected to both SC and MC components as the second network interface (eth1). Despite the name, this subnet may also carry signaling (SIP) and media (RTP) traffic. Signaling Subnets 1 and 2: These subnets carry signaling (SIP) traffic. They are connected to SC as the third and fourth network interfaces (eth2 and eth3), respectively. The subnets are optional, as the OAM subnet may also carry signaling traffic. Media Subnets 1 and 2: These subnets carry media (RTP) traffic. They are connected to MCs as the third and fourth network interfaces (eth2 and eth3), respectively. The subnets are optional, as the OAM subnet may also carry media traffic. All subnets must reside in the same Availability Zone of your Virtual Private Cloud (VPC). The following figure illustrates the Mediant CE network architecture: Figure 2-3: Mediant CE Network Architecture - AWS Version 7.2 11 Software-based SBC Series

Mediant Cloud Edition SBC 2.3.1 Cluster Subnet The Cluster Subnet is used for the following tasks: Internal communication between Mediant CE components Accessing AWS API (for IP address management) Mediant CE uses private addresses in the Cluster Subnet.

Installation Manual 6. Licensing Mediant CE 6.2 Installing the License Key The procedure for installing the License Key depends on whether the Mediant CE has one or two SC instances. 6.2.1 Installing the License Key on a Mediant CE with One SC Instance Note: The License Key installation process includes an SC instance reset and is therefore, traffic-affecting. To minimize the disruption of current calls, it is recommended to perform this procedure during periods of low traffic. To install a License Key file for Mediant CE with One SC Instance through Web interface: 1. Login to the Mediant CE Web Interface 2. Open the License Key page (Setup menu > Administration tab > Maintenance folder > License Key). 3. Back up the currently installed License Key, as a precaution. If the new License Key does not comply with your requirements, you can re-load this backed-up License Key to restore the Mediant CE s original capabilities. To back up the License Key, click and save it as a file on your PC. 4. Click the Load File button, navigate to the License Key file on your computer, and then select the file; the Apply New License Key button appears. The License Key page uses color-coded icons to indicate the changes between the previous License Key and the newly loaded License Key. Note: If you want to cancel the installation, reset the SC instance without saving the configuration. 5.

The License Key file is loaded to the active SC instance. 2. The active SC instance sends the file to the redundant SC instance. 3. The redundant SC instance saves the file to disk and is reset to activate the new license key. 4. The active SC instance saves the file to disk (without a reset). 5. The SC instances undergo an HA switchover, whereby the active instance becomes redundant and the redundant instance becomes active. Current calls are maintained and handled by the active SC instance (previously the redundant instance). 6. The redundant SC instance (previously the active instance) is reset to activate the new license key. Non-hitless Upgrade: The License Key is installed on both SC instances simultaneously (both are reset at the same time). Therefore, this method is trafficaffecting and current calls are terminated. The installation process is as follows: 1. The License Key file is loaded to the active SC instance. 2. The active SC instance sends the file to the redundant SC instance. 3. Both SC instances save the file to disk and are reset to activate the new license key. Installation Manual 30 Document #: LTRT-10842
