A VoIP (Voice over Internet Protocol) gateway is a device that acts as a relay between an IP network and telephone lines. It converts digital IP packets on an IP network (T.38) and analog voice data on telephone lines (T.30) into each other. By installing a VoIP gateway, you can send faxes from IP fax-compatible devices to G3 fax-compatible devices, or receive faxes.
