Welcome to the Java smppapi homepage!
This project is an implementation of the Short Message Peer to Peer (SMPP) protocol. SMPP is used by applications to communicate with Service Centres to send and receive short messages to & from mobile devices.
The current implementation (0.3.x) supports versions 3.3 and 3.4 of the specification. Work has begun on implementing version 5.0 of the specification.
The smppapi supports communication over the TCP/IP protocol but is extensible, allowing other network implementations to be added.
The smppapi is released under the Lesser GPL.
