GSM gateways reduce telephone expenses (Least Cost Routing)
GSM gateways connected to PBX systems will make calls via one of the mobile radio modules installed in the gateway, if an employee makes a call to a mobile number from his or her office extension. This will normally be the same type of mobile radio module used in everyday mobile phones. As a general rule, calls from mobile to mobile cost less than calls from the fixed network to a mobile. GSM gateways (VoIP GSM Gateways) offer additional benefits when combined with voice over IP (VoIP).
