7 1 Introduction This document provides an overview of the required protocols for Wavenet Hosted Voice, as well as the ports thats are used. Identifying the protocols and ports that are to be used is the first step in desigining a security policy using firewalls and/or access control lists (ACL) to restrict access to only the required ports. As part of successful Customer Premises Equipment (CPE) deployment and operation all required devices, features and applications should be located in the sections below and the corresponding LAN/WAN requirements should be implemented and tested. 2 Overview Not all firewall configurations need ports to be opened. If the customer is running inside to outside rules the ports should be opened to allow the Wavenet Hosted Voice protocols out. There should be no reason for the customer to open ports inbound on the firewall. IMPORTANT NOTE: If a router and/or firewall is SIP Aware / has a SIP ALG enabled, we recommend that this functionality be turned OFF. 3 Port Requirements This section identifies all TCP/UDP ports that are required for proper Wavenet Hosted Voice operation. The next sections will be brocken down to different Network elements and required protocols. Some sections below are split into INTERNET CONNECTION and DIRECT CONNECTION. INTERNET CONNECTION means that the device operates with Wavenet Hosted Voice over the Internet, for example from a standard Business DSL Service. DIRECT CONNECTION means that the device operates VIA Wavenet Hosted Voice s VPN connectivity service, Wavenet s VPN Connectivity service provides a way to connect your MPLS VPN network to Wavenet next generation voice application.
