A Digital VoIP Gateway is a network device that converts digital voice signals from traditional telephony systems (like E1/T1 PRI lines) into data packets that can be transmitted over IP networks using VoIP (Voice over Internet Protocol). It acts as a bridge between legacy telephone infrastructure (such as PBX systems) and modern IP-based communication systems.
Here's how it works:
In essence, a Digital VoIP Gateway helps businesses migrate to VoIP without replacing their existing telephony hardware, ensuring cost savings, better scalability, and seamless integration into modern unified communication systems.
Here's how it works:
- Signal Conversion: It receives digital signals from sources like ISDN PRI lines and converts them into IP packets using codecs such as G.711, G.729, etc.
- Protocol Support: It supports various signaling protocols like SIP and H.323, which ensure smooth call setup, routing, and termination.
- Routing & Management: Advanced gateways offer intelligent call routing, failover options, security features (like firewall and encryption), and remote management via web interfaces or SNMP.
- Scalability: They are available in different port densities to support small offices or large enterprises, offering anywhere from 1 to 32 or more E1/T1 ports.
