VoiSmart® vGSM-II card is a PCI adapter capable of making GSM network services available to the hosting system. It may be used in several applications: voice, data and SMS gateways, SMS interactive systems, remote control, etc... This board allows systems integrators to transform highly priced fixed to mobile voice traffic into a much cheaper mobile to mobile call management, with considerable savings. No external gateways needed in your asterisk PBX. 100% compatible with EU and US GSM networks (900 / 1800 / 1900 Mhz) and with Brazil and Japan networks.
VoiSmart® vGSM-II is a complete redesign of the vGSM card with improved functionalities and performance, in particular it supports full digital audio handling, SIM routing and remotization, an additional physical serial port for each module, several signalling LEDs and much more.
