26 | * @brief Sofia SIP Transaction API implementation | |||
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 | |||

2114 | * | |||
2115 | * Creates a new transport and binds it | |||
2116 | * to the port specified by the @a uri. The @a uri must have sip: or sips: | |||
2117 | * scheme or be a wildcard uri ("*"). The @a uri syntax allowed is as | |||
2118 | * follows: | |||
2119 | * | |||
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. | |||

4244 | * NTA object. | |||
