Router Compatibility Guide

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 Hosted PBX service in your office, or, if you are already using our service, before making changes to your existing network.If your router is not listed, please contact a Jive representative to discuss. Should you have additional information on a device and would like to add your findings to our list, please contact us.

General Router Notes

For optimal voice qualiy, we recommend the following setup:

  • Use a standalone modem, or if one is not availble from your ISP, bridge your modem/router to an external router.
  • Maintain a physical connection to the phones. We do not recommend using a wireless internet service, or connecting the phones through wifi.
  • If possible, the phones should be given their own separate interet connection, physicaly separate from the one used by your computers. If this is not possible, then use a small business grade router that has reliable QoS.

Some router settings can cause unpredictable connectivity issues such as dropped audio and calls that fail to ring :

  1. SIP ALG – should be disabled.
  2. Consistent NAT. The router should keep the NAT port for the phones the same for as long as the phones are connected.
  3. MTU. Make sure the router’s MTU setting matches what your ISP recommends for the modem they supplied.
  4. Single WAN. The phones will not work across dual WAN connections. If there is load balancing, it must be disabled, and if there is an outage failover, the threshold should be set to a very high number such as 30 seconds.
  5. Use a single router.

Devices believed compatible after changes

Zxyel

  • Current Status: Possibly compatible after changes
  • Sugestions: 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"

Tomato Firmware Routers

  • Current Status: Possibly compatible after changes
  • Sugestions: Adjust router settings
  • Comments: We have encountered a scenario in which a router running the Tomato firmware would only let one phone register at a time. We were able to resolve this problem by entering the router settings, under 'Advanced' and then 'Conntrack/Netfilter', where we enabled the SIP option for 'Tracking/NAT Helpers.' The router on which this was encountered was an Asus RT N16 but this issue and resolution may apply for other routers running Tomato.

SMC 3100

  • Current Status: Possibly compatible after changes
  • Sugestions: 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.

Netopia

  • Current Status: Possibly compatible after changes
  • Sugestions: 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 therouter, 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

Netgear FVG318

  • Current Status: Compatible after Changes
  • Sugestions: Update firmware and disable SIP ALG
  • Comments: This router is known to cause issues related to storing configuration and failed firmware downloads with Aastra series phones. 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'.

Motorola Surfboard

  • Current Status: Compatible after changes
  • Sugestions: Disable SIP ALG and ensure appropriate firmware is running
  • Comments: The following changes/checks are required: 1) Must be running firmware v3.3 or higher 2) Must have SIP ALG disabled.

Cisco/Linksys RV082, RV016, RV042, RV042G

  • Current Status: Compatible if correct firmware version is used. May require settings change.
  • Sugestions: Not Recommended
  • Comments: Comments: This family of routers will work well with our Hosted PBX services so long as the firmware version on the unit is v4.2.1.02. Other versions may cause issues. The MTU settings under 'Setup' -> 'Network' should be set to 1500 (Cable) or 1492 (DSL). If this router has issues with phones not ringing, the issue may be UDP sessions being closed early. Our staff have resolved this by upgrading to 4.2.1.02 firmware, then going to the hidden page at https://(router LAN IP)/f_general_hidden.htm and then changing the UDP Timeout from 30 seconds to 300 seconds.

Juniper – Netscreen

  • Current Status: Compatible after Changes
  • Sugestions: Disable SIP ALG
  • Comments: You must disable the SIP ALG on the Netscreen router. Navigate to the 'Configuration' page and choose 'Advanced'. Then choose ALG and un-check the SIP check box.
