FXS VoIP Gateways

Value packed FXS Gateways from VoIP Supply will reenergize your phone system’s ROI.

VoIP Supply knows that deploying a new VoIP phone system doesn’t always mean that you need new VoIP phones to go along with it. Connecting to VoIP service via an FXS Gateway is a simple and cost effective way to wrestle extended returns from your existing analog phones or fax machine.

FXS Gateways employ RJ11 ports that will leverage your analog office phones and fax machines to communicate with your new VoIP PBX system with VoIP protocols and will encode/decode the voice signal with voice codecs.

All of our FXS Gateway gateways carry a standard manufacturer’s warranty, are supported by our in-house team of VoIP gateway experts and are compliant with most VoIP protocols and codecs.
