| /** |
| * 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. |
