Introduction

This document provides a list of most of the TCP and UDP ports that a Cisco CallManager 3.3 environment utilizes. This document provides important information for when you configure both Quality of Service (QoS) and Firewall/VPN solutions on a network when there is an Architecture for Voice, Video and Integrated Data (AVVID) solution implemented.

Note: Refer to Cisco CallManager 4.1 TCP and UDP Port Usage for a list of ports that Cisco CallManager 4.1 uses.

Other AVVID Products

For Cisco Unity, refer to the Cisco Unity and Quality of Service (QoS) paper that describes any additional ports used (primarily between Microsoft Exchange and Cisco Unity) that are not listed in the table in this document. The actual Cisco Unity voice ports are registered via the TAPI service provider (TSP) using the Skinny protocol (TCP port 2000).
