Network Equipment Setup and Compatibility Guide

ATTENTION: The settings and potential configurations for equipment found on this page are provided for your benefit and may not necessarily reflect the same hardware, firmware, version, make or model of equipment you are attempting to implement or configure on your network.

Overview

The following list provides information about routers and firewalls and their ability to support VoIP. Suggested configurations should be used to prevent issues with VoIP traffic on your network, but do not represent all possible configuration options. Some equipment is incompatible with VoIP and as such requires replacement.

General Settings

SIP ALG (Application Layer Gateway) and SPI (Stateful Packet Inspection) need to be disabled on most routers and firewalls, if equipped. This is usually found on the Security/Firewall tab in the device’s web interface. In cases where the router or firewall does not have these options or the options cannot be disabled, you may have to exchange the equipment for something more compatible.

If you have equipment that is not listed here? Consult our Router Settings Info page for general tips.
