 +
 +==== {uri.duri} ====
 +
 +Return the destination URI for routing, keeping only schema, host, port and transport parameter. If port and transport are not in the original value, they are also not in the returned value.
 +
 +Example:
 +
 +<code c>
 +$var(ouri) = "sip:alice@server.com:5060;nat=yes;transport=tcp;line=xyz";
 +$var(duri) = $(var(ouri){uri.duri}); # => "sip:server.com:5060;transport=tcp"
 +</code>
 +
 +==== {uri.saor} ====
 +
 +Return the SIP AoR, keeping only schema, user and host. If user is not in the original value, it is also not in the returned value.
 +
 +Example:
 +
 +<code c>
 +$var(ouri) = "sip:alice@server.com:5060;nat=yes;transport=tcp;line=xyz";
 +$var(suri) = $(var(ouri){uri.saor}); # => "sip:alice@server.com"
 +</code>
 +
 +==== {uri.suri} ====
 +
 +Return the simple URI for routing, keeping only schema, user, host, port and transport parameter. If user, port and transport are not in the original value, they are also not in the returned value.
 +
 +Example:
 +
 +<code c>
 +$var(ouri) = "sip:alice@server.com:5060;nat=yes;transport=tcp;line=xyz";
 +$var(suri) = $(var(ouri){uri.suri}); # => "sip:alice@server.com:5060;transport=tcp"

 "a=1;b=2;c=3"{param.value,c} = "3" "a=1;b=2;c=3"{param.value,c} = "3"

 +
 +'name' can be a pseudo-variable
 +
 +'delimiter' allows you to specify a single character to use as the parameter delimiter. For example, when parsing HTTP URL query strings use '&'.
 +
 +==== {param.in,name[,delimiter]} ====
 +
 +Return 1 if the parameter 'name' is found in parameters list, 0 if not found.
 +
 +Example:
 +<code>
 +"a=1;b=2;c=3"{param.in,c} = 1

 +
 +===== URI Alias Transformations =====
 +
 +Transformations related to URI alias values (**addr~port~protoid**).
 +
 +==== {urialias.encode} ====
 +
 +Encode SIP URI to alias value.
 +
 +<code c>
 +"sip:127.0.0.1:5060;transport=udp"{urialias.encode} => "127.0.0.1~5060~1"
 +</code>
 +
 +==== {urialias.decode} ====
 +
 +Decode from alias value to SIP URI.
 +
 +<code c>
 +"127.0.0.1~5060~1"{urialias.decode} => "sip:127.0.0.1:5060;transport=udp"
