Integration of the GSM-card in company's telephone system provides phone calls cost reduction especially for «office — mobile phones» direction. Also the GSM-card is the fastest and easiest way to establish telephony communication in locations where landlines are unavailable or costly.

The model enables user to insert up to 8 SIM-card into SIM-holders or commutate SIM-cards remotely using remote SIM-management technology provided by SIM-server Polygator.

The card operates under OS Linux (all *NIX systems are supported). It is compatible with IP-PBX Asterisk thanks to native Asterisk-module (PGGSM) and Linux-driver by Polygator.
