CallBack
What Is CallBack?
CallBack is a function used for external PBX extensions. With the CallBack you can
easily reduce costs of external extensions. The extension with the CallBack enabled
only alerts the PBX or sends an SMS in the appropriate form and the PBX calls back to
this extension. After answering the call, the external extension can dial through the
PBX as in the case of a direct call. So you do not need an expensive fixed payment
tariff for all external extensions but only for your PBX SIM cards. This function is
subject to licence.
CallBack Setting
Find the CallBack configuration menu in the menu. The Routing – Routing Objects
menu is divided into two parts. The left side is used for management and the right side
for configuring the selected object. The context menu on the left consists of the
following options:
Add – use this option to add a new object for CallBack.
Delete – use this option to delete a selected object.
Rename – use this option to rename a selected object.
Default – use this option to delete all current objects of this menu and create
two default CallBack objects – one for calls and one for SMS messages.
Update – use this option to add the default CallBack objects preserving the
current ones. If default objects have already been created, their parameters are
set to default values.
On the right–hand side of the menu you can find the following parameters:
Ring CallBack
Name – only displays the name of the selected object.
CallBack delay [s] – defines the delay between the CallBack recognition and
execution.
Ring destination – this destination is used in the case of successful CallBack
immediately after call answering by the external extension.
Ring detection time [s] – defines the ringing time for incoming calls from a
extension with the CallBack. If this timeout expires (the calling user does not
hang up), the call is routed to Destination after timeout and behaves as a normal
call and the CallBack function is not used.
Destination after timeout – this destination is used after the Ring detection
timeout for another call routing. In the case of SMS CallBack, this destination is
not used.
