SMS/USSD

SMS and USSD support for Wikipedia

The simplest Vumi system consists of a transport worker and an application worker.

A transport worker is responsible for sending messages to and receiving messages from users in the big wide world. Transport mechanisms Vumi supports include SMPP, XMPP, Twitter, IRC, HTTP and a variety of mobile network aggregator specific messaging protocols. The application worker processes messages from a transport and sends replies – it holds the application logic. Vumi workers communicate over RabbitMQ.

A XMPP based demo is available with the following jabber ids: wikipediavumi@gmail.com and wikipediavumitest@gmail.com
