ProSBC:Cloud:AWS Installation

This page is intended to give assistance to people launching an instance of ProSBC using an Amazon Machine Image (AMI) on Amazon Web Service (AWS).
NOTE The old installation guide is here: AWS installation

Instantiate a ProSBC

  • After logging in your Amazon account, click on “EC2” in the main AWS console:
AWS Management Console 2022-07-28 16-27-37.png

  • Be sure you are in the correct region, on the left menu click on “AMIs” and select “Private image” to locate FreeSBC/ProSBC AMI:

  • Launch the FreeSBC/ProSBC image.

  • Name the instance and add any necessary tag

  • Select the instance type and its resources. The recommended instance type is:
    • m5.large (2 vCPU, 8 GiB)
  • Supported instance type are:
  • This is the list of approximate performances for different AWS instance types. Results may vary according to configuration.

  • For later access to the FreeSBC/ProSBC SSH console you will need to select a Key Pair to secure the login. You can also create a new Key Pair in case you need.

  • In "Networking Settings" select "Create security group". We recommend that you simply open "All Traffic" on your own IP addresses to whitelist it in AWS firewall on "Source", once all your IPs are listed click on "Add security group rule": (note that the SBC contains its own internal firewall)

  • In "Configure Storage" change the Volume Size to 40Gb and select volume type to GP2.

  • Finally review the summary of your instance and start the creation process clicking on "Launch Instance". Be aware, from this moment you will be billed by Amazon for the instance resources:

  • You should receive the confirmation of the launching process, this process will take some minutes until the instance is available, You can view your instance clicking on “View Instances”:

  • After a few minutes your instance should be running and available to be configured:

Optional: Elastic IP Creation section

  • AWS will automatically provide and allocate a dynamic public IP to your instance, this will allow you to access from the IPs you whitelisted before to the Public IP allocated to your instance. For ProSBC servers the purpose is to interact with other SIP elements as part of a VoIP cloud telecom infrastructure, TelcoBridges strongly recommends associating an Elastic IP to your instance, which is, in short, to associate a fixed public IP to your SBC. For more information about how to associate an Elastic IP to your instance please check the official documentation in AWS here.

Enable SR-IOV enhanced networking

By default M5 instances have enhanced networking enabled. If you want to use any other instance, like m4 type instance, you need to check if enahnced networking is enabled or not.

It is very important to enable "enhanced networking" for tbrouter to have access to the network devices on the VM.

This must be done before completing the initial web portal configuration. Please shut down the instance before entering the serial number and all other information and set SR-IOV

There are two types of enhanced networking, we need the second one.

1) Elastic Network Adapter (ENA)

2) Intel 82599 Virtual Function (VF) interface

Install the AWS CLI

Get security credentials for the command line

On the AWS web portal, click on your account name and choose "My Security Credentials"

Expand the "Access keys" section

Create a new key, you will need the AWSAccessKeyId and AWSSecretKey

Open a CLI and execute the aws cli commands

 aws configure

Paste the access key ID and key that you previously obtained along with your default region.

Show if the enhanced networking is enabled

Make sure to replace the example instance ID with your own AWS instance ID

 aws ec2 describe-instance-attribute --instance-id i-0123456789abcdef1 --attribute sriovNetSupport


     "InstanceId": "i-0123456789abcdef1",
     "SriovNetSupport": {
         "Value": "simple"

Not enabled:

     "InstanceId": "i-0123456789abcdef1",
     "SriovNetSupport": {}

To enable the sriov enhanced networking, first turn off the instance then do:

 aws ec2 modify-instance-attribute --instance-id i-0123456789abcdef1  --sriov-net-support simple

Accessing the ProSBC

Accessing the ProSBC web portal

  • Open a web browser to the management IP of the ProSBC, on port 12358. Example if your Instance public IP address is, the URL would be:

You should get to the ProSBC Configuration Wizard

Take note that it may take a while for the ProSBC system to make the Web Portal available (around 3-5 minutes).

Installing AWS Instance with CloudFormation Template

AWS CloudFormation is a service that helps you model and set up your AWS resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. Telcobridge created a CloudFormation template to reduce the time spent on ProSBC AWS installation. Click on the following link to the ProSBC CloudFormation installation: ProSBCAWS CloudFormation Installation

Upgrading the instance type

You can upgrade the instance type in AWS based on your requirements. Click on the following link for instance type upgrade ProSBC AWS Intance Upgrade
