Matrix SIMADO GFX44 is a gateway to interface GSM and Plain Old Telephone System (POTS) networks. On the GSM side, it supports 2G Quad-Band and 3G Tri-Band operation allowing it to work with any GSM/3G network. On the POTS side FXS interfaces are supported. Incoming calls on GSM ports can be routed on FXS ports. Outgoing calls from FXS are routed on GSM ports depending on the least cost routing logic. It can handle calls on all the ports simultaneously allowing full traffic on all the ports.

Existing PBX users can avail the low tariff of GSM networks by connecting SIMADO GFX44 with the PBX without changing their existing infrastructure. The users continue to make and receive calls without worrying on which network their calls are routed. Matrix SIMADO GFX44 routes the calls either on GSM network depending on the destination numbers dialed by the users. In addition, SIMADO GFX44 can also be used without a PBX in a stand-alone mode.

Intelligent and flexible routing is forte of the Matrix SIMADO GFX44. Least Cost Routing (LCR) algorithm encompasses dialed number based routing facilitating selection of the most cost-effective route. Numbers received from calling network are converted by Automatic Number Translation (ANT) to match with the numbering plan of the destination network.

The SIMADO GFX44 is very easy to install and operate. In addition, the Jeeves (a Windows based multi-lingual GUI tool) is supplied to configure various parameters. Antenna mixers (4 to 1) are built-in and hence only one antenna is required. The SIMADO GFX44 can be mounted on a wall or any table surface.
