GSM OpenVox VS-GWM420G 4-port module

GSM module OpenVox VS-GWM420G - an update of the VS-GWM400G module that cannot but please. OpenVox engineers have developed a completely new system architecture: previously, each module was equipped with a separate processor, now the entire system is controlled by one powerful 4-core processor based on the VS-GWM420 Control Board control module. This solution makes the GSM module more accessible, and the entire system even more reliable and fault-tolerant.
