ActivePBX Router Compatibility Tables

Introduction

The following is a list of known routers and modems which we have determined to be compatible, incompatible or compatible with changes to the configuration of the device. We have also provided a list of devices which we are aware of but have not yet tested ourselves.

We highly recommend checking all network equipment on site against this list before deploying our Business voice-over-IP service in your office. If your router is not listed, please contact an ActivePBX Phone representative to discuss. Should you have additional information on a device and would like to add your findings to our list, please contact us.

Whenever possible you should choose a router that has QoS (Quality of Service) if you plan to share the same internet connection with non-VoIP services (such as desktop computers). We also recommend that you always make sure your modem is bridged and updated to the newest firmware available before troubleshooting unless otherwise specified by this guide. This list is updated frequently and we recommend you check back periodically for any updates.

Linksys RV082, RV016, RV042

Current Status: Compatible
Recommendation: Recommended
Comments: This family of routers is recommended for use with our VoIP services and appears compatible with the most recent firmware revision. The MTU settings under 'Setup' -> 'Network' should be set to 1500 (Cable) or 1492 (DSL). The RV series offer an excellent QoS feature which is an advantage over most competing routers.

If you have a large number of devices to connect to your router, the 4-port RV042 may not offer enough ports for you. In this case, choose the RV082 or RV016 for their larger number of ports, or alternatively purchase an unmanaged switch and connect it to your RV042 to increase its port capacity.

Devices believed compatible after changes


2Wire Routers and Modems

Current Status: Possibly compatible after Changes
Recommendation: Disable SIP ALG or Bridge to Supported Router
Comments: To use this router you need to login to the web interface for the router and disable the 'SIP ALG' setting on it. If this option is not available you will need to bridge the router to a compatible router so that the 2wire router acts as a simple modem rather than a router.

If bridging is not possible either, you must replace this device as it will prevent you from using our service.

Cisco Routers (general)

Current Status: Compatible; may require changes
Recommendation: Confirm model with ActivePBX Phone Services
Comments: The Cisco routers we have encountered appear to be quality devices that are compatible with our service, but may require some changes.

Cisco 837: The router's NAT service for SIP should be disabled, with the command:
no ip nat service sip udp port 5060

D-Link DIR-615

Current Status: Compatible after Changes, Hardware Revision B Only
Recommendation: Disable SIP ALG
Comments:
This applies to Hardware Revision B only. Other hardware revisions are not compatible with VoIP as they do not have the disable SIP ALG option.

This router has known issues with VoIP services if SIP ALG is not disabled. We recommend disabling the SIP ALG setting on the router available in firmware releases 2.2.4 and higher. This option is available within the firewall settings under the 'Application Level Gateway (ALG) Configuration'. The SIP option should be unchecked.

D-Link DIR-625

Current Status: Possibly Compatible after Changes
Recommendation: Disable SIP ALG
Comments:
We recommend disabling SIP ALG through the DIR-625's web interface. After the change, this router appears to be compatible and able to serve up to three or four phones. Customers who have tried to connect a larger number of phones to this router have found that the additional phones fail to register with our server. We would not recommend this router for a larger-scale deployment as it does not appear to perform reliably.

Aastra phones on this router require frequent reprogramming and firmware replacement. This router appears to work with VoIP services with the SIP ALG setting is disabled. The router does not work properly with VoIP with the SIP ALG setting enabled (which is enabled by default). You should make sure you have the most recent firmware for this router before using it. To disable the SIP ALG, first login to your router and select 'Rules' from the left hand side menu. Next, check the box that says 'Disable SIP ALG'.

[Back to Top]

Netopia

Current Status: Possibly compatible after changes
Recommendation: Disable SIP ALG or replace device
Comments:
Netopia has SIP Passthrough "on" by default and will not work with VoIP services properly unless SIP ALG is disabled. (Or SIP ALG in newer models) In order to work with voice-over-IP, you must turn SIP Passthrough (SIP ALG) off. Note that not all Netopia routers may allow this change; if yours does not you must replace the device with a compatible router in order to use our service.

The SIP ALG setting is not in the web gui. You have to telnet into the router, then type. Each line is a new command.

configure
set ip sip-passthrough off
save
exit
Restart

On the Netopia 4622xlt
Telnet into the device
Use the arrow keys to highlight 'quick menu' and press "ctrl-n"
That brings you to the console.

type:

ip nat alg sip enable no
save
exit
restart

Recommendation: Bridge device to supported router
Comments: This router is not compatible with VoIP services unless it is bridged. We recommend bridging the router to alternative router so that it acts as a modem only.

[Back to Top]

Zxyel

Current Status: Possibly compatible after changes
Recommendation: Disable SIP ALG or bridge device to router
Comments:
This router is not compatible with VoIP services without modifications. We recommend either bridging the device to another router or disabling the SIP ALG. To disable the SIP ALG you must first telnet into the router/modem. Choose (24) System Maintenance and (8) Command Interpreter Mode. From the command line type:

ip nat service sip active 0

You will receive the message "SIP ALG Disable"

[Back to Top]

Linksys WRT54G, WRT54GX, WRT54GL, WRT54GS

Current Status: Not Compatible
Recommendation: Replace Device or Replace Firmware
Comments: This router is not recommended for use with VoIP services using the stock firmware from Linksys. This model router is known to damage and modify SIP packets in such a way that it prevents VoIP packets from being formatted correctly and can cause a multitude of problems.

You may be able to install custom firmware such as DD-WRT (http://www.dd-wrt.com) as a replacement. Note that the procedure does require some technical knowledge and ability. The DD-WRT firmware allows you to disable SIP ALG and enable QOS (Quality of Service), but this has not been tested in our labs yet.

Netgear Routers (General)

Current Status: Not Compatible
Recommendation: Replace Device
Comments:
Most Netgear routers will not work with VoIP services and have been blacklisted on our network to prevent customer issues. Most Netgear routers lack the ability to disable the internal SIP ALG which causes intermittent issues with phone service.

We recommend avoiding this brand of router until Netgear makes it possible to disable the internal SIP ALG setting on all of their routers to be compatible with voice-over-IP.

Devices not yet Tested


Cisco Pix

Current Status: Untested
Recommendation: Untested
Comments:
We have Untested this router in our labs, but the following information may be helpful.

The cisco pix firewall requires that in version 7.0 or later look at the "inspect" fields. (Prior to version 7 it was called "fixups" not "inspect".) Make sure that the "inspect SIP" field is NO. "Oo inspect sip" is the proper setting. With 'inspect sip' on the PIX firewall replaces the internal IP address of the phone with the external IP address. We use both pieces of information to accurately deliver the call. The internal IP address must be inside the SIP packet for proper functioning.
