SMPP (Short Message Peer-to-Peer Protocol) is an open message
transfer protocol that enables users to interact with an SMS
centre. The protocol defines the information which needs to be
exchanged between the user and the SMSC and the operations
associated with the exchange of SMS messages.
SMPP functions allow the user to connect to SMSC to send
and/or receive SMS. The NetDecision fully supports SMPP v3.3 and
SMPP v3.4. The client operates as SMPP transceiver.
To communicate with an SMSC, you must first open SMPP session by
using SmppOpen function. In the end the SMPP
session must be closed by using SmppClose function.
