3CX Phone System v12.5 Beta – Important Change – New Port Numbers

With the release of 3CX Phone System v12.5 Beta, changes have been made to the port numbers making the deployment of 3CX Phone System much simpler. For a correct operation of 3CX Phone System, administrators should forward the correct new port numbers and make the following changes:

HTTP and HTTPS Port Changes

The ports previously used for HTTP and HTTPS were port 5000 for HTTP and port 5001 for HTTPS. This change affects Phone Provisioning URLs, access to all websites (Management Console and Reporter), and Presence in 3CX Bridges. The new ports are:

  • Port 5000 becomes port 80 for HTTP.
  • Port 5001 becomes port 443 for HTTPS.

The Phone Provisioning URLs need to be updated by simply removing port 5000 from the URL. For example:

  • The provisioning link in V12: http://example.3cx.com:5000/provisioning/{randomfoldername}

Becomes:

  • The provisioning link in V12.5: http://example.3cx.com/provisioning/{randomfoldername}

Since the Provisioning link has been modified, 3CXPhone Clients need to be re-provisioned otherwise they will not be able to connect to 3CX Web Presence Servers. To avoid these issues, access the 3CX Management console, click the Extensions node, select all the extensions in the list and click “Send Welcome Email” button.

3CX Bridge Presence URL

From the management console:

  1. Expand the “Bridges” node.
  2. Click on each bridge which has 3CX Presence enabled and navigate to the “3CX Presence” tab.
  3. In the “Receive Presence Information” sectionremove port :5000 or :5001 from the URL.

For example:

  • http://example.3cx.com:5000/MyPhone/MPWebService.asmx

Becomes

  • http://example.3cx.com/MyPhone/MPWebService.asmx

Media Server Ports

The port ranges for Media (voice and video) have changed. Administrators need to edit their firewall rules and forward the following range of ports: 9000-9199 UDP Only (Total of 200 ports) .
Ports 9000-9099 will be used to transmit media for SIP VoIP Calls, whilst ports 9100-9199 are used to transmit media for WebRTC VoIP Calls.

HTTPS Certificates

From Version 12.5 and higher, any certificates generated at installation time can be backed up and restored using the 3CX Backup and Restore tool. This way administrators can ensure that client certificates remain the same.

x86 Installations

3CX Phone System can only be installed on x64 based Windows Operating Systems. Support for x86 has dropped.

Winforms Removed

The 3CX Winforms Management Console has been removed from the 3CX Phone System installation. This is deprecated. 3CX Management Console is Web Based only from now on.
