What is GOIP?

    GoIP, also known as GOIP (GSM Over IP), is a device that converts traditional telephone signals into network signals. It serves as a series of GSM gateways designed to establish a direct connection between the GSM (Global System for Mobile Communications) network and VoIP (Voice over Internet Protocol). Here's a professional and detailed description of its functionalities, roles, and application scenarios:

**Functions:**

1.  **SIM Card Support**: GoIP devices can accommodate multiple手机SIM cards, typically supporting up to four cards, which allows for the use of different phone numbers and services.
2.  **Voice Call Conversion**: It enables voice calls to be made over an IP-based network, converting traditional GSM calls into VoIP calls and vice versa
3.  **SMS Functionality**: GoIP devices often provide the ability to send SMS messages in bulk, which can be useful for marketing campaigns or notifications.
4.  **Remote Control**: These devices can be controlled remotely, allowing for operations such as call forwarding, call transfer, and call recording from different locations.
5.  **Separation of Human and Machine**: The device can be operated from a distance, which means the user does not need to be physically present where the GoIP device is located.

**Roles:**

• Bridge Between Networks: Its primary role is to act as a bridge between the traditional GSM network and the modern VoIP network, facilitating communication between the two.
• Cost-Effective Communication: By converting calls to VoIP, GoIP can significantly reduce the cost of international or long-distance calls.
• Anonymity and Privacy: Due to its ability to remote operate and switch numbers, it provides a level of anonymity and privacy in phone communications.
