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.
