| 27 | * |
| 28 | * This source file has been divided into sections as follows: |
| 29 | * 1) agent |
| 30 | * 2) tport handling |
| 31 | * 3) dispatching messages received from network |
| 32 | * 4) message creation and message utility functions |
| 33 | * 5) stateless operation |
| 34 | * 6) dialogs (legs) |
| 35 | * 7) server transactions (incoming) |
| 36 | * 8) client transactions (outgoing) |
| 37 | * 9) resolving URLs for client transactions |
| 38 | * 10) 100rel reliable responses (reliable) |
| 39 | * 11) SigComp handling and public transport interface |

| 811 | * |
| 812 | * Create an NTA agent object. The agent |
| 813 | * object creates and binds a server socket with address specified in @e url. |
| 814 | * If the @e host portion of the @e url is @c "*", the agent listens to all |
| 815 | * addresses available on the host. |
| 816 | * |
| 817 | * When a message is received, the agent object parses it. If the result is |
| 818 | * a valid SIP message, the agent object passes the message to the |
| 819 | * application by invoking the nta_message_f @e callback function. |
| 820 | * |
| 821 | * @note |
| 822 | * The @e url can be either parsed url (of type url_t ()), or a valid |
| 823 | * SIP URL as a string. |
| 824 | * |
| 825 | * @note |
| 826 | * If @e url is @c NULL, the default @e url @c "sip:*" is used. |
| 827 | * @par |
| 828 | * If @e url is @c NONE (iow, (void*)-1), no server sockets are bound. |
| 829 | * @par |
| 830 | * If @p transport parameters are specified in @a url, agent uses only |
| 831 | * specified transport type. |
| 832 | * |
| 833 | * @par |
| 834 | * If an @p maddr parameter is specified in @e url, agent binds to the |
| 835 | * specified address, but uses @e host part of @e url when it generates |
| 836 | * @Contact and @Via headers. The @p maddr parameter is also included, |

| 2120 | * @code url <scheme>:<host>[:<port>]<url-params> @endcode |
| 2121 | * where <url-params> may be |
| 2122 | * @code |
| 2123 | * ;transport=<xxx> |
| 2124 | * ;maddr=<actual addr> |
| 2125 | * ;comp=sigcomp |
| 2126 | * @endcode |
| 2127 | * |
| 2128 | * The scheme part determines which transports are used. "sip" implies UDP |
| 2129 | * and TCP, "sips" TLS over TCP. In the future, more transports can be |
| 2130 | * supported, for instance, "sip" can use SCTP or DCCP, "sips" DTLS or TLS |
| 2131 | * over SCTP. |
| 2132 | * |
| 2133 | * The "host" part determines what address/domain name is used in @Contact. |
| 2134 | * An "*" in "host" part is shorthand for any local IP address. 0.0.0.0 |
| 2135 | * means that the only the IPv4 addresses are used. [::] means that only |
| 2136 | * the IPv6 addresses are used. If a domain name or a specific IP address |
| 2137 | * is given as "host" part, an additional "maddr" parameter can be used to |
| 2138 | * control which addresses are used by the stack when binding listen |
| 2139 | * sockets for incoming requests. |
| 2140 | * |
| 2141 | * The "port" determines what port is used in contact, and to which port the |
| 2142 | * stack binds in order to listen for incoming requests. Empty or missing |
| 2143 | * port means that default port should be used (5060 for sip, 5061 for |
| 2144 | * sips). An "*" in "port" part means any port, i.e., the stack binds to an |
| 2145 | * ephemeral port. |
| 2146 | * |
| 2147 | * The "transport" parameter determines the transport protocol that is used |
| 2148 | * and how they are preferred. If no protocol is specified, both UDP and TCP |
| 2149 | * are used for SIP URL and TLS for SIPS URL. The preference can be |
| 2150 | * indicated with a comma-separated list of transports, for instance, |
| 2151 | * parameter @code transport=tcp,udp @endcode indicates that TCP is |
| 2152 | * preferred to UDP. |
| 2153 | * |
| 2154 | * The "maddr" parameter determines to which address the stack binds in |
| 2155 | * order to listen for incoming requests. An "*" in "maddr" parameter is |
| 2156 | * shorthand for any local IP address. 0.0.0.0 means that only IPv4 sockets |
| 2157 | * are created. [::] means that only IPv6 sockets are created. |
| 2158 | * |
| 2159 | * The "comp" parameter determines the supported compression protocol. |
| 2160 | * Currently only sigcomp is supported (with suitable library). |
| 2161 | * |
| 2162 | * @par Examples: |
| 2163 | * @code sip:172.21.40.24;maddr=* @endcode \n |
| 2164 | * @code sip:172.21.40.24:50600;transport=TCP,UDP;comp=sigcomp @endcode \n |
| 2165 | * @code sips:* @endcode |
| 2166 | * |
| 2167 | * @return |
| 2168 | * On success, zero is returned. On error, -1 is returned, and @a errno is |
| 2169 | * set appropriately. |
