| 2134 | * ;comp=sigcomp | ||||||||
| 2135 | * @endcode | ||||||||
| 2136 | * | ||||||||
| 2137 | * The scheme part determines which transports are used. "sip" implies UDP | ||||||||
| 2138 | * and TCP, "sips" TLS over TCP. In the future, more transports can be | ||||||||
| 2139 | * supported, for instance, "sip" can use SCTP or DCCP, "sips" DTLS or TLS | ||||||||
| 2140 | * over SCTP. | ||||||||
| 2141 | * | ||||||||
| 2142 | * The "host" part determines what address/domain name is used in @Contact. | ||||||||
| 2143 | * An "*" in "host" part is shorthand for any local IP address. 0.0.0.0 | ||||||||
| 2144 | * means that the only the IPv4 addresses are used. [::] means that only | ||||||||
| 2145 | * the IPv6 addresses are used. If a domain name or a specific IP address | ||||||||
| 2146 | * is given as "host" part, an additional "maddr" parameter can be used to | ||||||||
| 2147 | * control which addresses are used by the stack when binding listen | ||||||||
| 2148 | * sockets for incoming requests. | ||||||||
| 2149 | * | ||||||||
| 2150 | * The "port" determines what port is used in contact, and to which port the | ||||||||
| 2151 | * stack binds in order to listen for incoming requests. Empty or missing | ||||||||
| 2152 | * port means that default port should be used (5060 for sip, 5061 for | ||||||||
| 2153 | * sips). An "*" in "port" part means any port, i.e., the stack binds to an | ||||||||
| 2154 | * ephemeral port. | ||||||||
| 2155 | * | ||||||||
| 2156 | * The "transport" parameter determines the transport protocol that is used | ||||||||
| 2157 | * and how they are preferred. If no protocol is specified, both UDP and TCP | ||||||||
| 2158 | * are used for SIP URL and TLS for SIPS URL. The preference can be | ||||||||
| 2159 | * indicated with a comma-separated list of transports, for instance, | ||||||||
| 2160 | * parameter @code transport=tcp,udp @endcode indicates that TCP is | ||||||||
| 2161 | * preferred to UDP. | ||||||||
| 2162 | * | ||||||||
| 2163 | * The "maddr" parameter determines to which address the stack binds in | ||||||||
| 2164 | * order to listen for incoming requests. An "*" in "maddr" parameter is | ||||||||
| 2165 | * shorthand for any local IP address. 0.0.0.0 means that only IPv4 sockets | ||||||||
| 2166 | * are created. [::] means that only IPv6 sockets are created. | ||||||||
| 2167 | * | ||||||||
| 2168 | * The "comp" parameter determines the supported compression protocol. | ||||||||
| 2169 | * Currently only sigcomp is supported (with suitable library). | ||||||||
| 2170 | * | ||||||||
| 2171 | * @par Examples: | ||||||||
