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 ?
