A GoIP (GSM over IP) gateway is a device that connects GSM (mobile) networks to VoIP (internet) networks. It acts as a bridge, allowing voice calls and SMS messages to be exchanged between the two. GoIP gateways are commonly used to integrate mobile networks with VoIP systems, enabling businesses to make cost-effective calls and manage communication more efficiently.
Key Features and Functionality:
GSM to VoIP Conversion:
The core function is converting voice and SMS traffic from the GSM mobile network into VoIP packets that can be transmitted over the internet.
SIM Card Slots:
GoIP gateways typically have SIM card slots, allowing them to register with a GSM network and make calls like a regular mobile phone.
VoIP Protocol Support:
They support VoIP protocols like SIP (Session Initiation Protocol), enabling them to connect to IP PBX systems and other VoIP devices.
Call Routing and Cost Savings:
GoIP gateways can be used to route calls over the most cost-effective network (GSM or VoIP).
Scalability:
GoIP gateways come in various models with different numbers of channels (e.g., 1, 8, 16, 32), allowing for scalability based on communication needs.
Other Features:
Some models offer features like IMEI change, support for SIM banks, and web-based management.
Common Applications:
- Integrating Mobile Networks with VoIP Systems:Connecting a company’s existing PBX or IP telephony system to the mobile network.
- Call Termination:Routing calls from VoIP networks to mobile networks for termination.
- SMS Marketing and Messaging:Sending and receiving SMS messages via the gateway.
- Call Centers:Utilizing GoIP gateways to enable communication between call center agents and mobile users.
- Remote Communication:Providing voice and SMS services in areas with limited or no traditional phone line access.
Examples of GoIP Models:
- GoIP 1:A single-channel GSM VoIP gateway, typically used for basic integration or in smaller setups.
- GoIP 8:An 8-channel gateway, suitable for businesses with moderate call volume.
- GoIP 16/32:Larger gateways with 16 or 32 channels, designed for larger enterprises or call centers.
