+/**
+ * simple_pjsua.c
+ *
+ * This is a very simple but fully featured SIP user agent, with the 
+ * following capabilities:
+ *  - SIP registration
+ *  - Making and receiving call
+ *  - Audio/media to sound device.
+ *
+ * Usage:
+ *  - To make outgoing call, start simple_pjsua with the URL of remote
+ *    destination to contact.
+ *    E.g.:
+ *	 simpleua sip:user@remote
+ *
+ *  - Incoming calls will automatically be answered with 200.
+ *
+ * This program will quit once it has completed a single call.
