 Free Form Template Variables In the Template fields on the Postliminary tab, and when specifying a 
Request-URI or other headers for outbound registration (see “Add Outbound 
Registration Dialog Box” on page112), you can use the variables in the table 
below entered as 
#variable name#
 (case insensitive). The system replaces the 
variables with the corresponding values as shown below. 
You can also use these variables (without # delimiters) in a customized script. 
In addition to the variables, you can enter any values acceptable for the 
Request-URI or To header. 
For the Request-URI, the contents of the Template field specify only the URI 
portion of the full Request line. Depending on network configuration, a route 
header may be required. 
For the To header, the contents of the Template field specify the complete 
header except for the header name (“To”). 
The @ symbol is always removed if no user is present in the result.
