Overview

A small business or office manager joining analog phone lines to a VoIP system gets four FXO line ports and one FXS phone port in the Grandstream gateway. It routes calls over SIP, sends faxes over IP and fails over to a backup server automatically.

Linking existing phone lines to a SIP system lets an office keep its numbers while moving to VoIP. Setup assumes a SIP provider or server and comfort with network settings.

Who it's for

Small businesses, hotels and dormitories with existing lines get a gateway with failover and fax support. Households wanting simple home phone service should use a basic adapter.

Pros and cons

Pros
  • Four line ports plus a phone port
  • Power outage lifeline
  • Fax over IP
  • SIP server failover
Cons
  • Needs a SIP server or provider
  • Configuration takes expertise
  • Only one FXS phone port

Performance notes

Call quality depends on the network path to the SIP server, so a congested link causes choppy audio. The lifeline relay connects the phone port straight to a line when power fails.
