The 2N® VoiceBlue 3G is a GSM/UMTS gateway designed with the goal to cut costs as much as possible. This is ensured by an efficient, automated, cost-saving solution based on routing according to time, code or free minutes. The CallBack service is able to save on roaming charges on trips abroad. If your company has more branches in several countries, you will appreciate the possibility to call mobile networks there completely free of charge using VPN tariffs. Unlike our competitors’ products, the 2N® VoiceBlue Lite has a unique advantage. This is the 2N® Mobility Extension feature, by which your mobile phone will become a full-value fixed line replacement. To facilitate this feature you can also use the mobile applications Symbian and Windows Mobile for operating systems. 2 UMTS channels model. US power supply.
