Is a GSM Gateway right for business calling?

A GSM Gateway is a device that connects GSM mobile networks with VoIP or traditional telephone systems. In simple terms, it allows businesses to route calls between mobile networks and IP-based systems, helping reduce call costs and improve connectivity.

It is widely used in offices, call centers, and multi-branch businesses where mobile call traffic is high.

How Does a GSM Gateway Work?
A GSM Gateway works by inserting SIM cards into the device. When a call is made from an IP PBX or VoIP system, the gateway routes the call through the SIM card over the GSM network instead of a traditional phone line.

• Converts VoIP calls into GSM calls
  
  
• Uses SIM cards to connect with mobile networks
  
  
• Routes incoming GSM calls to IP PBX or SIP systems
  
  
• Supports two-way communication (VoIP ↔ GSM)
  

This helps businesses take advantage of lower mobile call rates.
