Dinstar DWG2000E-4G

VoIP SIP GSM gateway Dinstar DWG2000E-4G gateway with four ports from DINSTAR, which can connect GSM networks to VoIP networks. This GSM/VoIP gateway supports SIM Bank and can be expanded to 8 GSM channels.

Dinstar DWG2000E-4G is a 4-channel gsm-voip gateway created on the basis of the DWG2000C series gateway, but qualitatively different from it both in external design and firmware architecture. Due to significant improvements to the gateway software by Dinstar programmers, as well as the use of completely new high-quality components during assembly, the DWG2000E model has outpaced the DWG2000C in terms of performance. The gateway supports all existing gSM standards in Ukraine. This GSM/VoIP gateway supports SIM Bank and has the ability to expand to 8 GSM channels. Each GSM channel can be programmed separately and establish communication with an IP-PBX, or can be grouped as one communication channel with an IP-PBX.
