    I am working with a project on communication between SIM900 GSM module and a server. Project consist of a client device(enabled with gsm/gprs) and a server system. The client can communicate with server on demand but how can the server communicate to a GSM/GPRS module on demand (since the GSM/GPRS module doesn't have a static but only dynamic ip).
    Client can poll the server every-time but its not the method what we are looking for but - the Server should call GSM/GPRS modules on demand basis,
    please help me to find a way to do that one.

    Each GSM module has a IMEI number. Maybe you can broadcast a query asking a particular module to respond. Something similar was used in the Point To Multipoint Radio Systems.
