SMPP API / General information

SMPP (Short Message Peer-to-Peer Protocol) is a protocol that allows you to communicate with SMS Center. The protocol defines the information necessary for the exchange of data between the user and the SMSC as well as the operations defined in the context of sending SMS messages. Each query made by SMPP has an assigned response. As part of the SMPP protocol in SerwerSMS.pl it is possible to:

• sending SMS text messages (max 918 characters, the SMS x 6)
• to receive delivery reports
• specify message encoding (is supported 7bit ASCII or UTF-8)
• identifying the message header (ie. the name of the sender)
• incomming messages support (MO)
• support for long messages sent as message_payload, SAR and UDH

To connect and send messages using SMPP, you must have the appropriate software. Recommended and popular programs that are checked with SerwerSMS.pl are eg kannel (www.kannel.org) or ozeki (www.ozeki.hu). In the further part of the documentation there are sample configurations.
