A GSM gateway, also known as a GSM VoIP gateway or simply a GSM bridge, is a device that allows for direct routing between IP, digital, analog, and GSM networks. By doing so, it creates a cost-effective and efficient communication channel.
GSM gateways are useful for reducing the cost of calling from VoIP to a GSM network and vice versa. This is particularly beneficial for businesses that make a significant number of calls to mobile networks, as it eliminates the need to pay high network charges.
Here’s how a GSM gateway works:
- Incoming calls: When an incoming GSM call is detected, the GSM gateway converts the GSM call into a VoIP call. This VoIP call can then be routed directly to an IP-PBX system or a VoIP telephone, depending on the system setup.
- Outgoing calls: For outgoing calls, the IP-PBX system or VoIP phone sends the call to the GSM gateway. The gateway then converts this VoIP call into a GSM call and sends it out through the mobile network.
GSM gateways also offer the ability to utilize multiple GSM channels. This means that with a single device, several simultaneous calls can be made or received, which can significantly enhance the call handling capacity of a business.
The key benefits of a GSM Gateway include cost savings, improved quality of service, business continuity in the event of a landline failure, and the ability to take advantage of mobile calling plans and features.
