The 2N StarGate VoIP is an alternative to our GSM/UMTS Gateway which can be connected to your private branch exchange via a modern VoIP interface. For companies making high numbers of calls to mobile networks, it significantly reduces the cost of telephone calls. Its efficient automated cost-saving solution can find the cheapest route and always uses the most advantageous SIM card for the connection.
The gateway integrates some very useful functions that your employees can use at any time. They include e.g. CallBack, which eliminates roaming fees or an SMS service for unanswered calls, whereby the gateway automatically sends out an SMS message with the caller’s details if a call is missed. The gateway also makes it possible to send bulk SMS messages directly from your email client. Naturally, the automated cost-saving solution once again selects the most advantageous route.
Modern communication is no longer just about phoning and sending emails. Besides being an efficient communication solution, the GSM/UMTS StarGate VoIP Gateway also houses a great direct marketing tool. Thanks to this feature it can significantly reduce overhead costs, even for large companies, and open new opportunities to reach customers and business partners.
