Overview
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 32GSM channels. 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.
