What is GSM?

Global System for Mobile Communications (GSM) is a mobile communication standard that VoIP systems can interconnect with to enable mobile call routing.

GSM (Global System for Mobile Communications) is a global mobile communication standard used by mobile carriers to provide voice, SMS, and data services. In VoIP environments, GSM interconnection allows VoIP systems to route calls to mobile networks or terminate calls on GSM endpoints. GSM is particularly useful in mobile VoIP applications where calls can be handed off between Wi-Fi and GSM networks. This capability enhances call continuity and mobility for users on the go. Additionally, GSM gateways enable businesses to reduce costs by routing calls through mobile networks rather than traditional PSTN lines. Integrating VoIP with GSM improves communication flexibility, enabling seamless connectivity between mobile and IP-based networks.
