Main function:
1, Routing between PSTN and GSM
Users can program the numbers they need to dial through GSM. The Follow Me GSM Gateway will choose the proper path (GSM or PSTN) to make the phone call - This is ideal when calling work colleages and can be used for further cost savings when calling mobile phones on other networks depending upon the mobile phone tariff.

2, ACR Dialler (Automatic Call Routing)
In addition to GSM/PSTN router, the Follow Me GSM Gateway also has all features of an ACR dialer providing users with the ability to use alternative telephone companies and calling cards for cheaper PSTN calls.

3, Answering a GSM Phone Call by Normal Telepohone
When the handset receives a call, the normal telephone will ring. User can then pick up the handset and answer the call.

4, Call Diverter (Follow Me)
When users are out of the home or office, they can set the number where they are. If anybody calls them from the landline PSTN number, the unit will forward this call to the number through the mobile phone. It also works in opposite direction.


5, Transit between PSTN and GSM Network
Users can call into the Follow Me GSM Gateway device to the landline PSTN number, and then dial out from the GSM, or in opposite direction enabling mobile users to call into the GSM Gateway and make a call over the landline (ideal when making international calls). Password can be set to protect unauthorised access.
