Remote User Phone Setup and Requirements


Setting up your phone and optimizing your network to use Fuze services as a remote user.

Applies To

  • Fuze Desktop
  • Requirements and Optimization


This article is intended to provide you information for the setup of your phone at home, and the requirements for your home network device to use Fuze services.

The pictures shown here are of a Poly VVX model device. Your device may look different, but the same basic principles apply.

Connecting Your Phone to Power (if necessary)

Most home network devices (modems/routers) do not provide Power over Ethernet (POE). As such, you will likely need a power supply for your phone to work properly. If you need a power supply, please contact your administrator.

Plug the AC power cord into the port on the back of the phone and into a power source.

Connecting to Your Network

Plug an Ethernet cable into the port marked with the Ethernet symbol and/or labeled LAN on the back of the phone, and connect the other end to your network device.

Daisy Chaining to a Computer

Some phones allow you to daisy chain your network connection from your phone to your computer. After connecting your network device to the Ethernet port on the back of the phone, follow these steps:

  1. Plug a second Ethernet cable into the port with the computer icon and/or labeled PC on the back of the phone.
  2. Plug the other end of that cable into the Ethernet port on your computer.

Network Requirements

Fuze Support has discovered certain home network devices that will not support call Session Initiation Protocol (SIP), which can impact the reliability of Fuze services.

Possible symptoms of an incompatible device include:

  • Call quality issues
  • Dropped calls
  • Lack of incoming calls
  • Message Waiting Indicator (MWI) not working
  • Buddy watch not working
  • Call transfer not working

If you are using Fuze Desktop, you can run Fuze Checkup before joining a meeting to test your Fuze setup. You can also check your audio and network quality directly in the application.

Fuze Remote User Device Requirements

If a remote user is using an Internet Service Provider (ISP) provided device that does not have user-manageable settings, they may need to provide their own device or contact their ISP to request a replacement device with user-manageable settings.

These are the requirements for a home modem or modem/router combination device to use Fuze services:

  • SIP ALG must be disabled.
    • Many of today's commercial routers implement SIP ALG (Application Level Gateway) and come with this feature enabled by default.
  • UDP timeout must be set to 360 or higher

    Some modem manufacturers allow you to put the device into bridge mode, disable SIP ALG and modify UDP timeout using the web interface. However, the firmware on the modem does not support the change.

  • TCP timeout must be set to 600 or higher
  • Domain Name Server (DNS) on your DHCP server (modem, router or other device) must be set to:
    • Primary -
    • Alternate -

Desk Phone Requirements

For remote users who are using a desk phone (Polycom or Yealink), the following are required:

  • The ethernet cable from the router/access point must be connected to the LAN port on the desk phone.
  • VLAN settings are not supported. If the desk phone has a VLAN enabled, have the user follow the steps below to remove it.
    1. On a Polycom device, select Menu > Settings > Advanced > enter password 456 or 876
    2. On a Yealink device, select admin* > Administration Settings > Network Configuration > Ethernet Menu > VLAN Menu
    • VLAN ID must be blank
    • LLDP needs to be disabled
    • CDP Compatibility needs to be disabled

If a phone is already bound to a voice service, the administrator password can be found under Admin code in the Fuze Portal (Navigate to UC Configs > PBX Settings).

If you are working from an office location (not from your home), the above VLAN, LLDP, and CDP settings will likely need a different configuration. Please contact your IT department for the correct VLAN, LLDP, and CDP settings for your location.

Optional Configurations

If the home network device (wireless router or access point) is too far away from the user's computer or phone, Fuze Support recommends the following solutions:
