Preparing the Server for Installation
The following tasks must be completed before installing PortSIP PBX.
System Preparation
Ensure the system date and time are correctly synchronized.
Performing the installation using
sudois recommended.Assign static IP addresses:
If the PBX server is on a LAN, assign a static private IP address.
If the PBX server is on a public network, assign both a static public IP and a static private IP.
Install all available OS updates and service packs before installing the PBX.
Do not install PostgreSQL on the PortSIP PBX server.
Disable all power-saving options for the system and network adapters (set the system to High-Performance mode).
Do not install TeamViewer, VPN software, or similar tools on the host machine.
The PortSIP PBX must not be installed on a server acting as a DNS or DHCP server.
Firewall and Network Requirements
The following ports must be allowed by the firewall and must not be used by other applications.
UDP: 5060, 5066, 25000–34999, 45000–65000
TCP: 5061, 5063, 5065, 5067, 8882, 8883, 8887, 8888, 10443
❗Important If the PBX is deployed on a cloud platform such as AWS, Azure, or other providers, you must also open these ports in the cloud platform’s firewall or security group.
Installing PortSIP PBX
❗ Important Follow every step in this guide in order. Do not skip any steps unless the guide explicitly says you can.
Step 1: Download Installation Scripts
Run the following commands to download the installation scripts and initialize the environment:
Step 2: Set Up the Docker Environment
All commands must be executed in the /opt/portsip directory.
Run the following command to install the Docker and Docker-Compose environment:
If you are prompted with:
Enter Y and press Enter to continue.
Step 3: Create and Run the PBX Docker Instance
The following command creates and runs the PortSIP PBX Docker instance on a server with the public IP address 66.175.221.120. If the PBX is deployed on a LAN without a public IP, replace 66.175.221.120 with the PBX server’s private LAN IP address.
Command Parameters Explained
-p: Specifies the directory for storing PBX data.-a: Specifies the PBX server IP address (public or private, depending on deployment).-i: Specifies the PBX Docker image version.-f: (Optional) Specifies a separate directory for storing call recording files.
The -f parameter is optional and allows you to specify a separate path for storing recording files. If this parameter is not specified, the recording files will be stored in the path defined by the -p parameter.
For example, if you mount a device or an external NAS device to /pbx/recordings and want to store the recording files there, you can create and run the PBX Docker instance using the following command:
If you have mounted a local disk or an external NAS device at /pbx/recordings, you can store recording files there by running:
Configure the PortSIP PBX
After the installation completes successfully, access the PBX web portal at: https://66.175.221.120:8887

Click on "Sign in as the administrator or dealer" to navigate to the administrator login page, as shown in the screenshot below. Enter admin as both the username and password to log in to the web portal.

❗Important For security reasons, change the default administrator password immediately after logging in.
For a new installation, the PBX automatically launches a Setup Wizard after the first successful login to the PBX web portal. This wizard guides you through the mandatory initial configuration steps.
1. Network Environment
In the Network Environment step, configure the PBX IP addresses.
The loopback interface (127.0.0.1) is not suitable for a private IP address. Only the static IP for the LAN where the PBX is located is allowed (do not use a DHCP dynamic IP).
Private IPv4 Address
Enter the server’s private IPv4 address.
If the server does not have a private IP address, enter the public IP address instead.
Public IPv4 Address
If the PBX server has a static public IP address, enter it in the Public IPv4 field.
If the server does not have a static public IP address, leave this field blank.

Important Notes on IP Configuration
The IP addresses configured here are used by SIP clients and IP phones to register with the PBX.
The configured IP address will act as the SIP server address and should be set as the Outbound Proxy Server on SIP endpoints.
Cloud Deployment: Both Private IPv4 and Public IPv4 addresses must be entered.
LAN Deployment: Only the Private IPv4 address is required.
2. SSL Certificate
To enable TLS transport for SIP and provide secure HTTPS access to the PBX Web Portal and REST API, a trusted SSL certificate must be configured during this step.
Domain Setup
You must have a web domain for the PBX. For example, you can purchase a domain from providers such as GoDaddy and point it to your PBX server’s IP address.
SSL Certificate Requirements
A trusted SSL certificate is strongly recommended to avoid browser security warnings.
Common certificate providers include:
DigiCert
GeoTrust
GoDaddy
Other trusted Certificate Authorities (CAs)
Note If you do not have a domain or SSL certificate, you may use the PBX server’s IP address as the Web Domain and proceed with the default certificate. However, PortSIP PBX uses a self-signed certificate by default, which will cause browsers to block the connection and display security warnings.
To purchase and prepare an SSL certificate, follow the guide: Preparing TLS Certificates for TLS/HTTPS/WebRTC.
After completing the steps in that guide, you will have the following certificate files:
portsip.pem— Certificate fileportsip.key— Private key file
Configuring the Certificate
In this guide, we assume the PBX web domain is uc.portsip.cc.

In the Web Domain field, enter:
uc.portsip.ccOpen the
portsip.pemfile in a text editor (such as Windows Notepad), and copy the entire contents into the Certificate File field.Open the
portsip.keyfile and copy the entire contents into the Private Key File field.
3. Transport Protocol
Click Add to create or review the transport protocols. By default, PortSIP PBX uses the following transport ports:
UDP:
5060TCP:
5063TLS:
5061

Customizing Transport Ports
You may change the default transport ports to any values that suit your deployment requirements.
❗Important
Ensure the selected port is not already in use by another application.
Use TLS whenever possible to secure SIP signaling.
Firewall and Client Configuration
After adding or modifying a transport protocol:
Update your firewall rules to allow traffic on the newly assigned port.
Configure IP phones and client applications to use the same transport protocol and port when connecting to the PBX.
The transport protocol and port configured here are used by:
SIP phones
Desktop and mobile client apps
Other SIP endpoints registering to the PBX
Click the OK button to complete the setup wizard.
Install the Instant Messaging (IM) Service
Starting with PortSIP PBX v22.0, an integrated Instant Messaging (IM) service is available, providing modern collaboration features such as:
One-to-one messaging
Group chat
The IM service requires a separate installation step.
For high-concurrency or large-scale deployments, we recommend installing the IM service on a dedicated server to achieve better performance and scalability.
Please follow the guide below to install and configure the IM service: Install IM Service
Install the Data Flow Service
Starting with PortSIP PBX v22.3.0, PortSIP introduces the Data Flow service, which delivers:
Advanced data analytics
Real-time metrics
Dashboards and wallboards
The Data Flow service is built on ClickHouse, a high-performance, column-oriented database optimized for analytics workloads. Due to its resource-intensive nature, this service must be installed on a dedicated, high-performance server and runs independently from the core PBX.
Please follow the guide below to install and configure the Data Flow service: Install Data Flow Service
Note Installing the Data Flow service is optional.
Call processing is not affected if it is not installed.
However, analytics, wallboards, and certain metrics features will be unavailable.
Restart the PBX to Apply the SSL Certificate
If in above step 2. SSL Certificate, you uploaded a trusted SSL certificate instead of using the default self-signed certificate, you must restart the PBX to apply the changes.
Run the following commands to restart the PBX:
Now that the PortSIP PBX is successfully installed, you can use https://uc.portsip.cc:8887 to access the PortSIP PBX web portal.
