Best price GOIP 16 port gsm gateway with 16 sim card port voip gateway
A VoIP GSM Gateway (GoIP) bridges voice communications between the GSM and the IP networks seamlessly.In principle, it consists of a GSM module and a VoIP module. With a SIM card installed, the GSM module registers to the GSM network for voice and SMS services.
GoIP comes with various models of 1, 4, 8, 16 and 32 ports goip gateway. When integrating in a VoIP system, GoIP is highly scalable in meeting customer's requirement on the number of channels (lines). In addition with its power functions, high voice quality, and low price, GoIP is an inevitable choice of many system integrators, call termination operatiors, small companies, and individuals.

The concept diagram below shows a simple VoIP network for call center application. It consists of a softswitch/IP PBX and VoIP clients such as an IP phone, a call center operator, and GoIPs. All VoIP clients are configured to register to the softswitch/IP PBX. For the GoIPs, each GSM channel is inserted with a valid SIM card in order to access the GSM network. Both incoming and outgoing calls between the VoIP and GSM/PSTN networks can now be realized.
