Voip (Voice over IP) Gateways are devices with multiple uses. VoiP gateways can be used to connect any existing phone system to SIP Trunks. They may also be used to attach a Voip phone system to regular copper phone lines. VoiP gateways can also be used to tie two or more different locations to each other over the internet. VoiP gateways are also used to expand existing VoiP based phone systems. For help deciding which VOIP gateway is right for you, please feel free to call us at 281-894-6606.
