Product Description

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. The VoIP module supports both SIP and H. 323 protocols which are widely used in the VoIP world. With account information configured properly, the VoIP module connects to the designated server for voice connection. Therefore, VoIP calls can then route to the GSM network and GSM calls can also route to the VoIP network. GoIP comes with various models of 1, 4, 8, and 16, 32 GSM 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.
