SMPP Version Information

This guide is intended for developers who want to use and integrate SMS over SMPP into their corporate information system. It describes the basic PDUs implemented in the Ozeki SMPP client.

What is the latest version of SMPP?

SMPP 5.0

Current SMPP Version Supported by Ozeki NG - SMS Gateway is: SMPP V3.3, SMPP V3.4 and SMPP v5.0

What are the different types of SMPP?

SMPP Connection Types: Sender, Receiver, Transceiver. Three connection types are supported when connecting to an SMPP server. A “sender,” or “send-only,” connection can only transmit, it cannot receive any messages on the connection.

For binding you can use transmitter, receiver and transceiver. If you have an option transceiver is recommended.

The SMPP PDUs that are implemented are:

  • BIND_TRANSCEIVER / BIND_TRANSCEIVER_RESP
  • BIND_TRANSMITTER / BIND_TRANSMITTER_RESP (was implemented for version v3.3, currently not used)
  • BIND_RECEIVER / BIND_RECEIVER_RESP (was implemented for version v3.3, currently not used)

  • ENQUIRE_LINK / ENQUIRE_LINK_RESP (Ozeki NG - SMS Gateway checks link activity every 300 seconds; if the link is not active, it will try to reconnect to the server.)
