Dimensions summary
You pay by the hour based on the EC2 instance type you launch. Each dimension maps to a specific AWS instance size across the t2, t3, t3a, m3, m4, m5, m5a, c3, c4, c5, and c5a families. Pricing scales with the compute size you choose, so larger instances with more CPU and memory cost more per hour. Smaller shared-burst instances like t2.micro and t3.micro sit at the lower end. You match the instance to your call volume and workload needs, and billing stops when you stop the instance.
Top-of-mind questions for buyers
The image runs the FreePBX Distro, which supports the commercial modules such as system administration, softphone connectivity, and fax tools. It also includes limited e-mail and ticket support. You match the instance size to your call volume and workload needs.
Hourly software charges accrue only while the instance runs. When you stop the instance, billing for the software stops. Underlying AWS storage fees for the volume may still apply while the instance is stopped, but the hourly software meter counts running time only.
Larger instances with more CPU and memory bill at a higher hourly rate. The t2, t3, and t3a families include shared-burst options for lighter loads. The c-family targets compute-heavy needs, while m-family instances balance CPU and memory. Match the size to your call volume.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
FREEPBX 17 and ASTERISK 21: Newly released FreePBX 17, updated also with Asterisk version 21.
The September 2025 update applies an OS update to Debian 12.12.
FreePBX 17 is a big refresh, changing the operating system to Debian 12, updating the code base to PHP 8, and removing some deprecated components such as chan_sip (former SIP channel driver, replaced by pjsip) and macro. All the familiar features of FreePBX remain, with the ability to add Sangoma commercial modules for extra functionality including call center/queue reporting, endpoint management, and mobile and desktop softphones.
TO UPGRADE from a previous version of FreePBX, use the Backup/Restore module to take a full backup of the older version and restore it on FreePBX 17.
Additional details
Usage instructions
ADMINISTRATION
Connect to your server over the web on port 80 (http://public-ip-address ) after launch to go through the setup wizard. For security reasons, your login and password have been pre-set to "admin" with a password of the instance ID (i-XXX...) found in your AWS EC2 Console. NOTE: In rare cases, the GUI will be locked and the instance ID password will not work. In those cases, you can unlock the GUI and set your own password using instructions found at https://simonics.freshdesk.com/support/solutions/articles/3000110612-gui-unlock-instructions
At first launch, it will take several minutes for services to start. Once you are able to connect to the web interface, you may still see "Can Not Connect to Asterisk." Wait another minute or two and refresh the page until this warning disappears.
SSH to the server using the "admin" user and the key you specified at launch. Become root with "sudo su -" to administer your server from the command line. Note that the IPv4 address displayed in Linux is the private IP address of your instance. To connect to your instance over the web or using SIP clients, you must use the public IP address. (TIP: Set an Elastic IP for persistence.)
INSTANCE SIZING
For production installations, select an instance type with at least 2GB of RAM. Functions requiring additional processing, such as transcoding, recording, and heavy call volumes, require larger instances.
SECURITY/FIREWALL
Specify a Security Group with least access in mind, considering the protocols you will use. Open SSH and HTTP(S) for management. You may also open HTTP(S) to end-user networks for User Control Panel (UCP) access. Allow SIP (5060/5160) and RTP (10000-20000 UDP) to your SIP endpoints and disable the GUI's built-in Firewall Module. Alternatively, open the Security Group more broadly for your SIP endpoints and use the GUI's Firewall Module to allow access and filter intruders.

What a scam
Doesn't work at all image has no FreePBX
Reviewed on Sep 25, 2021
Review from a verified AWS customer
After deploying this it just boots to a login screen. Web gui does nothing and says site not responding. FreePBX is free, you can deploy this on ubuntu or centos yourself, so there's no logical reason to pay a company monthly for free software especially when it doesn't even work. You should be ashamed.
