Polycom 3725-76302-001O manual Usage example, Dial Rule Action Output SIP Headers

	Call Server Configuration
Variable	Initial value
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");

The following table shows how different dial rule actions apply a preliminary script’s modified dial string to the output SIP headers in a SIP call.

Dial Rule Action	Output SIP Headers
Resolve to registered endpoint	The To header is replaced with the modified dial string. The request URI is
	based on the contact address of the registered endpoint, and not replaced
	with the modified dial string.
Resolve to external address	The To header and the request URI are both replaced with the modified dial
	string.
