Polycom 7000 manual Preliminary/Postliminary Scripting Functions, Usage example

Call Server Configuration

Variable	Initial value
DIAL_STRING	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:
INPUT_SIP_HEADERS	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.
	*/))
	{
	...
	}
OUTPUT_SIP_HEADERS	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");
