| 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 | |||

| 2105 | * follows: | |||
| 2106 | * | |||
| 2107 | * @code url <scheme>:<host>[:<port>]<url-params> @endcode | |||
| 2108 | * where <url-params> may be | |||

| 2110 | * ;transport=<xxx> | |||
| 2111 | * ;maddr=<actual addr> | |||
| 2112 | * ;comp=sigcomp | |||
| 2113 | * @endcode | |||
| 2114 | * | |||
| 2115 | * The scheme part determines which transports are used. "sip" implies UDP | |||
| 2116 | * and TCP, "sips" TLS over TCP. In the future, more transports can be | |||
| 2117 | * supported, for instance, "sip" can use SCTP or DCCP, "sips" DTLS or TLS | |||
| 2118 | * over SCTP. | |||
| 2119 | * | |||
| 2120 | * The "host" part determines what address/domain name is used in @Contact. | |||
| 2121 | * An "*" in "host" part is shorthand for any local IP address. 0.0.0.0 | |||
| 2122 | * means that the only the IPv4 addresses are used. [::] means that only | |||
| 2123 | * the IPv6 addresses are used. If a domain name or a specific IP address | |||
| 2124 | * is given as "host" part, an additional "maddr" parameter can be used to | |||
| 2125 | * control which addresses are used by the stack when binding listen | |||
| 2126 | * sockets for incoming requests. | |||
| 2127 | * | |||
| 2128 | * The "port" determines what port is used in contact, and to which port the | |||
| 2129 | * stack binds in order to listen for incoming requests. Empty or missing | |||
| 2130 | * port means that default port should be used (5060 for sip, 5061 for | |||
| 2131 | * sips). An "*" in "port" part means any port, i.e., the stack binds to an | |||
| 2132 | * ephemeral port. | |||
| 2133 | * | |||
| 2134 | * The "transport" parameter determines the transport protocol that is used | |||
| 2135 | * and how they are preferred. If no protocol is specified, both UDP and TCP | |||
| 2136 | * are used for SIP URL and TLS for SIPS URL. The preference can be | |||
| 2137 | * indicated with a comma-separated list of transports, for instance, | |||
| 2138 | * parameter @code transport=tcp,udp @endcode indicates that TCP is | |||
| 2139 | * preferred to UDP. | |||
| 2140 | * | |||
| 2141 | * The "maddr" parameter determines to which address the stack binds in | |||
| 2142 | * order to listen for incoming requests. An "*" in "maddr" parameter is | |||
| 2143 | * shorthand for any local IP address. 0.0.0.0 means that only IPv4 sockets | |||
| 2144 | * are created. [::] means that only IPv6 sockets are created. | |||
| 2145 | * | |||
| 2146 | * The "comp" parameter determines the supported compression protocol. | |||
| 2147 | * Currently only sigcomp is supported (with suitable library). | |||
| 2148 | * | |||
| 2149 | * @par Examples: | |||
| 2150 | * @code sip:172.21.40.24;maddr=* @endcode \n | |||
| 2151 | * @code sip:172.21.40.24:50600;transport=TCP,UDP;comp=sigcomp @endcode \n | |||
| 2152 | * @code sips:* @endcode | |||
| 2153 | * | |||
| 2154 | * @return | |||
