Greetings   When I use Session.SetVariable("transfer_ringback", "us-ring") from managed code the bridge fails with "NO_ANSWER" cause. If I use <action application="set" data="transfer_ringback=${us-ring}"/> from xml dial plan the call is stablished.   I have FS rev 13750 running on Windows.   This is a issue or I don't use properly transfer_ringback variable ?   Diego
