Few months ago I have brushed off dust out of one of my pet projects which I wrote back when I was working on Acision SMS gateway: SMPP SMSC simulator. SMPP is a binary protocol for sending SMS messages. It’s still very much used in Telco so this simulator might be of use to some people.
This application simulates a SMSC server – server which accepts SMS messages and handles its delivery to the mobile phone. If a delivery was successful and original message requested a delivery receipt, then the server sends it after configurable delay.
