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 page124), 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”).
