Least Cost Routing: direct routing between IP, digital, analogue and GSM networks.
GSM gateway
The VoIP GSM gateway enables direct routing between IP, digital, analogue and GSM networks, reducing the cost of telephone calls — especially IP-to-GSM.
Least Cost Routing (LCR) chooses the lowest-cost path. Multiple SIM cards and GSM modules can be integrated, so cheaper GSM-to-GSM calls can be originated instead of the more expensive IP-to-GSM.
