How to connect your PBX to mobile telephone networks


GSM network connection enables incoming and outgoing VoIP and GSM cellular calls. It is great alternate to PSTN, especially in area where GSM service is not available for VoIP call termination. GSM network connection provides significant advantages especially for calls from IP to GSM.

In order to create connection between your VoIP network and the GSM network, there is need for a GSM Gateway. The GSM Gateway is an excellent device for VoIP to wireless service where PSTN is not available or for mobile phone roaming via the VoIP network.
