The SMPP Gateway OCP tool maps on the Proto SMPP OpenSIPS module. It provides OpenSIPS the abilities to connect to multiple SMS Centers (via SMPP protocol) and to send and received SMS'es, by converting them from / to SIP MESSAGE requests - basically to perform the functionality of a bidirectional SIP to SMPP gateway
As the SMS Center records are kept in an SQL database, the tool provides standard DB provisioning operations : add, delete, search and listing of the records. As all the changes are done in database, to apply them into your OpenSIPS, you need to restart it.
Tool specific settings are configurable via the setting panel - see gear-icon in the tool header.
All settings are explained via ToolTip and have format validation.
