You can give staff outside your office a VOXO line that answers, holds, and transfers calls like an in-office extension — either through a browser-based softphone or a physical desk phone. This page covers what the worker’s location needs and the caveats to know before you set them up.

​
What the worker’s location needs

  • Internet — at least 5 Mbps up and down dedicated to phone traffic.
  • Router — if the modem and router are separate devices, set the router to bridge mode to avoid double-NAT registration problems. If your provider can’t enable bridge mode, ask them to disable SIP ALG instead.
  • Firewall — if a managed firewall controls the network, ask their IT to allow VOXO’s voice traffic. See Firewall IP Whitelist for the ranges and ports to allow.
  • Power — VOXO desk phone power supplies handle 100 to 240V, so they work on overseas mains without a converter.

​
Things to know

911 does not work internationally. Remote staff outside the U.S. can’t dial 911 from a VOXO phone and must use a local phone for emergencies.
Call quality follows the local internet — it depends on the remote location’s connection. If a remote phone or softphone won’t register after you’ve confirmed the internet is up and the router is in bridge mode, see Troubleshooting or contact support.
