Specification :

This product is a GSM to Analog Converter. Once you insert a GSM Chip, the device will produce a FXS line to allow a regular phone to be connected and used just like a local land line except your calls will go out the GSM network. This device can both receive and make calls.

1. Connect the RJ 11FXS line to a VOIP gateway such as Clarent, Cisco, Quintum or Vocaltech.
2. This allows you to send calls from the US to the VOIP gateway which is now connected to the local GSM network. This allows a much cheaper cost that previous methods
3. This product is not a VOIP gateway. It is a GSM Fixed Wireless Terminal that produces a Analog FXS phone line
4. Eliminate the cost of routing calls to and from wireless phone through the PSTN. With the Fixed Wireless Terminal, you can direct outgoing calls to wireless service and route inbound calls from wireless phones through the unit
5. Available in tri band 900 / 1800 / 1900 mhz
