 +  * Via
 +
 +For the rest of the headers works like **$hdr(name)**.

 +===== $lsock(expr) =====
 +
 +Get attributes for listen sockets (from corex module).
 +
 +The **expr** is an expression specifying what to match and return, the format is:
 +
 +<code>
 +matchid/value/field
 +</code>
 +
 +The **expr** can contain variables that are evaluated before parsing the expression.
 +
 +The **matchid** can be:
 +
 +  * n - match on name
 +  * l - match on listen address
 +
 +The **value** specifies what to match with.
 +
 +The **field** can be (only first character matches):
 +
 +  * name - return name
 +  * listen - return the listen address
 +  * advertise - return the advertise address
 +  * index - return the index in the list of all sockets
 +
 +Example:
 +
 +<code>
 +listen=udp:127.0.0.1:5060 advertise 127.0.0.1:5090 name "s0"
 +...
 +xinfo("$lsock(n/s0/listen)\n");
