The GoIP 8 is an 8-port VoIP GSM gateway that bridges cellular networks and IP-based networks. It features 8 dedicated SIM card slots, allowing it to handle up to 8 simultaneous voice calls or SMS transmissions by converting traditional cellular traffic into VoIP data, and vice versa. This device is widely implemented by medium-sized businesses, call centers, and VoIP terminators to drastically reduce call costs, bypass traditional PSTN landlines, and manage high-volume corporate communications.
Core Functionality
- Bi-Directional Bridging: Seamlessly routes incoming and outgoing calls from VoIP systems (like an IP PBX) to GSM cellular networks, and from mobile networks to IP channels.
- 8 Concurrent Channels: Operates 8 separate GSM channels concurrently. Each channel can be configured individually with its own IP PBX connection or pooled together into a single trunk.
- SMS & Routing Management: Beyond voice capabilities, the unit supports sending bulk SMS messages, flexible call forwarding, and customizable dial plans.
