$sid - Server ID

The value for server ID(server_id parameter).

$siz - Source IP address

$var(name) - Private memory variable(zero)

$var(name) refers to variables that can be used in configuration script, having integer or string value. This kind of variables are faster than AVPs, being referenced directly to memory location. <source lang=bash> $var(a) = 2; #-- sets the value of variable 'a' to integer '2' $var(a) = "2" #-- sets the value of variable 'a' to string '2' $var(a) = "sip:" + $au + "@" + $fd; #-- compose a value from authentication username and From URI domain. $var(a) = 3 + (7&(~2));

if( $var(a) & 4 ) {

 xlog("var a has third bit set\n");

} </source>

Setting a variable to $null is actually initializing the value to integer '0'. This type of script variable doesn't have &null value. <source lang=bash> $var(x) = $null

if ($var(x) == 0) { # this is true

 ...

} </source>
