Callback / Camp On
Description:
When extension users call a co-worker that does not answer or is busy, they can leave a callback
request for a return call. The user does not have to repeatedly call the unanswered extension back,
hoping to find it idle.
The System processes Camp On / Callback requests as follows:
1. You activate Camp On / Callback at a call to a busy extension. If you do not hang up, you will be
connected to your target extension as soon as he finished his call. So you Camp On to your target
extension until it becomes idle.
2. If you do not want to wait on your phone, you just hang up. You can have other calls in the
meantime or you just wait for his Callback. As soon as the target extension has finished his call
will the system automatically ring you. If you answer, the system will ring the target. If you do not
react to the call from the system, the system will cancel your callback request.
3. You call an extension that does no answer. As long as you hear the Ringbacktone, you can
activate Callback. As soon as the target extension did have any call and hangs up, the system
will initiate the callback.
You can have only one Callback / Camp on at a time.
