Preliminary/Postliminary Scripting Functions

The following table describes the functions you can use in a preliminary or postliminary script. The
parentheses at the end of the function name contain the parameters, if any, that the function accepts.
Polycom, Inc.
Initial value
Initially set to the dial string being evaluated. If the script modifies the
DIAL_STRING value, the modified value is used as the input to the dial rule
action.
For SIP, when the DIAL_STRING is modified by the script, it's use depends
on the dial rule action:
For SIP calls only, an associative array containing the SIP headers in the
received SIP INVITE message.
Usage example:
if(INPUT_SIP_HEADERS["Supported"].matches(/.*ms-forking.
*/))
{
...
}
An empty associative array. Headers that the script adds to this array replace
the corresponding headers in the received SIP INVITE message. If a header
added to this array isn't in the received INVITE message, it's added to the
INVITE message.
Usage example 1:
var list = OUTPUT_SIP_HEADERS.get("User-Agent");
if (list == null)
{
list = new java.util.LinkedList();
OUTPUT_SIP_HEADERS.put("User-Agent", list);
}
list.add("Someone. Not a RealPresence DMA 7000.");
Usage example 2:
var list = OUTPUT_SIP_HEADERS.get("Some-Custom-Header");
if (list == null)
{
list = new java.util.LinkedList();
OUTPUT_SIP_HEADERS.put("Some-Custom-Header", list);
}
list.add("Whatever you want");
