The GSM-192 is a solid high-technology design unit that allows a GSM Cellular Network to be easily connected to a Standard SLT phone, PBX System or as backup line for VoIP Solutions.


Reduction of Communications Billing

Easy to install, the GSM-192 can be used in conjunction with a existing PBX and LCR to route the customer GSM calls via the GSM gateway. This converts calls from fix land lines to GSM calls and can allow network charge saving on Telco Charges.

 Emergency Backup lines

The GSM-192 Gateway can be used for the backup of VoIP lines if they fail or the Network is damaged. If the communications fail, all calls made from the PBX or VoIP Server can be routed via the Sim cards in the Gateway, so keeping the communications channels open. VoIP can have an automatic fail over location, this could be set to the GSM-192 routers enabling incoming calls to be routed automatically.

Emergency Backup lines

When connected to an analogue telephone, the GSM-192 Gateway can be used as  for small remote offices or other locations that don’t have a fixed line infrastructure.
