| 21 | * simple_pjsua.c |
| 22 | * |
| 23 | * This is a very simple but fully featured SIP user agent, with the |
| 24 | * following capabilities: |
| 25 | * - SIP registration |
| 26 | * - Making and receiving call |
| 27 | * - Audio/media to sound device. |
| 28 | * |
| 29 | * Usage: |
| 30 | * - To make outgoing call, start simple_pjsua with the URL of remote |
| 31 | * destination to contact. |
| 32 | * E.g.: |
| 33 | * simpleua sip:user@remote |
| 34 | * |
| 35 | * - Incoming calls will automatically be answered with 200. |
| 36 | * |
| 37 | * This program will quit once it has completed a single call. |
