Dialog extension: "x-transfer"

The x-transfer dialog extension provides the ability to initiate a transfer of a call to a new call destination specified in a script using the hints attribute. In the script, when a hints.header is specified, the header is attached to a new SIP call as shown in the following code example.







<dialogstart src="'sip:test@127.0.0.1:5070'" type="'application/x-transfer'" hints='hints'/>

An example to this dialog extension in action is listed below for your convenience.

Note: You must escape reserved URI characters such as the & and # signs.
