GSM Terminal 8 ports for call termination 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 Features òEasy Installation. Just place SIM chip and connect a phone & you're ready to go òProvides single FXS line per modules òSet caller ID on and off òCompatible gain setting with Quintum, Clarent, Cisco and Vocaltech (proven test) òLow cost way to setup VoIP termination òSupport answer supervision mode with Reverse Batt / Reverse Polarity Signaling òSupports GSM 850/900/1800/1900 mhz òSignal Strength meter with LED òBlock unwanted prefixes òAble to show error with Front LED òPower supply and high antenna gain included òClear and Neat by using 1 antenna for 4 GSM module òAuto detection GSM network for 850 / 900 / 1800 /1900mhz
