Digital – ISDN BRI GSM Gateways
Clear sound and lower costs
Digital ISDN BRI gateways are the optimal solution for SOHOs and SMEs with a high number of calls to mobile networks. This is a modern and cost-effective product that ensures direct connection from a private branch exchange to GSM networks - resulting in significantly cheaper calls to mobile phones. An LCR automated cost-saving solution always selects the cheapest call route i.e. depending on the operator, GSM code or number of free minutes on SIM cards.
