Configure Jabber to Use Custom Audio and Video Port Range on CUCM 11.5.1

Introduction

This document describes the procedure to configure Cisco Jabber to use custom audio and video port range on Cisco Unified Communications Manager (CUCM) 11.5.1.

Contributed by Domhnall MacCormac, Cisco TAC Engineer.

Prerequisites

Requirements

Cisco recommends that you have knowledge of:

• Cisco Jabber
• Cisco Unified Communication Manager (CUCM)

Components Used

The information in this document is based on these software versions:

• Cisco Jabber for Windows 11.9.x
• Cisco Unified Communications Manager 11.5.x

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure you understand the potential impact of any command.

Configure

You can create a new SIP Profile or simply copy the Standard SIP Profile and modify the port range on your copied profile as follows:

• Navigate to Device > Device Settings > SIP Profile on the Cisco Unified CM Administration page
• Click on Find button to display all SIP profiles
• Click on the Standard SIP Profile and click on the Copy button
• Scroll down to the Media Port Ranges field and click on the radio button titled Separate Port Ranges for Audio and Video
• Specify the Start Audio Port, the Stop Audio Port, the Start Video Port and the Stop Video Port

Note: The Start port needs to be an even number and the Stop port needs to be odd number

Verify

Place a call from Jabber and confirm in the Jabber log that the ports specified in the outbound INVITE Session Description Protocol (SDP) message falls within the configured port range.

Troubleshoot

If the port specified in the INVITE SDP is not within the configured range, review the jabber.log file after a restart of the client to determine that the custom port range has been applied.

If the custom port range is not applied as per above log snippet, review the Jabber device configuration XML file on the TFTP server with a web browser (http://<TFTP_SERVER_ADDRESS>:6970/<DEVICE_NAME>.cnf.xml).
