Hello Tarik,

Ok, I see. 😊 You will probably learn it fast.

If you like, you can send me the module code or diff/patch by direct e-mail, and I (or my colleague) will create a pull-request for you.

Cheers,

Henning

Hello Tarik,

thank for the message, this new module looks indeed interesting!

Could you create a pull-request in our GitHub tracker for it? There might be some topics that other developers can also share some comments or suggestions.
We might also need to adapt a few things (e.g. the database table creation step) before it can be merged.

Thanks, and regards,

Henning Westerholt

> SMPP Module for Kamailio
> =====================
>
> This module implements SMPP (Short Message Peer-to-Peer) protocol
> support for Kamailio.
> It supports both SMPP v3.4 and v5.0 protocols and provides database
> authentication for SMPP clients.
>
> Features
> --------
> * SMPP v3.4 and v5.0 support
> * Database authentication
> * IP-based access control
> * Multiple concurrent binds support
> * Connection tracking
> * Automatic unbind on timeout
> * TLS/SSL support
> * Message queuing
> * Rate limiting
> * Character set conversion
>
> Configuration
> ------------
> The module can be configured in two ways:
>
> 1. Using Kamailio's main configuration file (kamailio.cfg):
> ```
> loadmodule "smpp.so"
>
> # Basic configuration
> modparam("smpp", "config_file", "/etc/kamailio/mod_smpp.conf") ```
>
> 2. Using the dedicated configuration file (mod_smpp.conf):
> The module looks for the configuration file at `/etc/kamailio/mod_smpp.conf`
> by default.
> You can override this location using the config_file parameter.
>
