VoIP Gateways bridge your existing analog or digital phone systems with modern Voice over IP (VoIP) networks. Whether you’re migrating from legacy PBX, adding fax capability, or connecting PSTN lines to SIP trunks, a quality VoIP gateway delivers reliable, cost-effective communication without ripping out your current infrastructure.
What Are VoIP Gateways and How Do They Work?
A VoIP gateway converts traditional telephony signals (analog FXS/FXO or digital T1/E1/PRI) into SIP-based IP packets — and vice versa. This lets you keep using desk phones, fax machines, and alarm systems while enjoying lower call costs, HD voice, and seamless integration with cloud or on-premise PBX systems.
