no callback on free or busy subscriber possible

[Ors]

SYSTEM
Call completly busy user :yes is managed.
Even when calling a free phone there´s no offer to callback in the display (dialig suffix without succeess, too)

[Ors]

Problem solved!
Changed routingmode at offhook from "direct routing" to "no routing" in the phone feature categories. Now it works!
(found out by importing the default configs step by step via Omnivista 4760...)

Thanks a lot to all of you for trying to help me.
