We are trying to push ring volume to our ip phones. Let's say that there are different levels of calls that are triggered by a own written application, this application handles several actions, and when action 1 is activated, several phones should ring with normal volume, when action 2 is activated the phones should ring with a louder volume, and so on. The phones should just ring, there is no actual conversation.
Until now we have only achieved something that simulates a press on the "volume up" button by XML. But this isn't what we are trying to achieve..
Many thanks in advance.
