Storing Into AWS S3
Last updated
Last updated
With PortSIP PBX, you can configure your system to store call recordings and compositions directly to your own Amazon Web Services (AWS) S3 bucket, instead of using local disk storage. This guide will walk you through setting up your AWS account or project to leverage this feature.
Note: Once external S3 storage is enabled, PortSIP PBX will stop storing uploaded files (such as voice prompts, profile pictures, and audio/video recordings) on the local disk. You will then be responsible for managing the security and lifecycle of your recorded content.
Use this feature if you need to comply with regulatory requirements that prohibit reliance on third-party storage solutions.
Warning: Please be aware of the following considerations when configuring Amazon S3 storage for your recordings:
Once Amazon S3 storage is activated, historical recordings stored on the local disk of the PBX server will no longer be accessible. Additionally, previously uploaded prompt files for queues, voicemail, IVR, and other voice announcements will need to be re-uploaded. Therefore, it is recommended to configure Amazon S3 storage immediately after completing the PBX installation.
Once the "Store to S3" option is activated, do not disable it. Disabling this feature will prevent the PBX from accessing historical recordings and will disrupt the process of storing new recordings on Amazon S3.

PortSIP PBX deployed on AWS EC2
AWS EC2 instance(s) located in the same region as your S3 bucket
Navigate to the Identity and Access Management (IAM) menu, select Access Management, and then click on the Add User button.
Input a name for the user, such as s3store, select Programmatic Access, and then click Next.
3. Click on the Create group button to create a new group.
4. Enter a name for the group, for example, portsip-pbx-s3, Choose AmazonS3FullAccess Policy name, and click the Create group button.
Once the group is successfully created, select it and click the Next button. You have the option to add tags to this user, or you can simply skip this step by clicking the Next button.
After the user is successfully added, make sure to note down the Access Key ID and Secret Access Key as shown.
Navigate to the Amazon S3 menu and click on the Create Bucket button to establish the S3 service that PortSIP PBX will utilize for storing recording files. Please pay attention to the Buket name, AWS Region, and the Object Ownership as the below screenshot.
The AWS Region must be chosen as the same region with your PBX installed. Remember to make note of the following, which you will need later:
The bucket-name.
The bucket-region. This is the AWS region where your S3 bucket is located.
Click on the Create button then the S3 bucket will be created.
Open the settings file:
On Linux is /var/lib/portsip/pbx/system.ini
On Windows is c:/programdata/portsip/pbx/system.ini
In the section apigateway, modify the value of the key storage to s3 as shown below.
Edit the section storage.s3 as shown below.
endpoint: This is an HTTP URL, replace the region-code with the actual region name. For example, if the EC2 and S3 region name is us-west-1, then it will be http://s3.us-west-1.amazonaws.com.
cred_id: It's the Access key ID of the IAM user noted whilst creating the IAM user.
cred_secret: It's the Secret access key of the IAM user noted whilst creating the IAM user.
region: The region name (region code) of the EC2 instance and S3. For example, if the region is us-west-2 then use the actual region name to replace it.
bucket: The bucket name of S3. In this example, it's portsip-pbx-storage.
Amazon S3 supports two URL styles for accessing stored objects: Path-Style and Virtual-Hosted–Style. By default, PortSIP PBX uses Path-Style URLs to ensure compatibility with certain AWS S3-compatible private storage services.
According to AWS best practices, Virtual-Hosted–Style is the preferred URL format. If you wish to configure PortSIP PBX to use Virtual-Hosted–Style with AWS S3, you can add a line into the [storage.s3] section as below:
To use Path-Style (default, recommended for S3-compatible services):
path_style = true
To use Virtual-Hosted–Style (recommended for official AWS S3):
path_style = false
After modifying the parameters for AWS S3, save the changes made to system.ini. You will then need to restart the PortSIP PBX for the changes to take effect.
Restart the PBX by performing the following commands:
Restart the Windows Server directly.
