i have GPRS modem which is connected to an energy meter which is located remote side...
Now iam running an RAS server in my PC which is connected to internet which has static ip ,
Now my server should detects that energy meter through ip address, this is not
possible because GPRS modem has dynamic ip address which not known to server..
So whenever the meter side modem (GPRS modem) connected to internet through GPRS , it should send that IP address to server PC (static ip) through internet...
