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 channel is inserted with a valid SIM card in order to access the 2G/3G/4G network.  Both incoming and outgoing calls between the VoIP and 2G/3G/4G networks can now be realized
