This document contains a description of what can be done if a phone number has not been blocked properly.

The Voicemail Script
====================

Logging
-------

The following explains how to use the voicemail script to check the phone number that should be blocked if the blocking does not work.

Mark the ``Trace-Checkbox``.
Afterwards click on Maintenance -> Trace to start the trace. Check boxes do not have to be set.

When a call is simulated the following is displayed:

   0:0270:324:3 - iprt.4.0(DBG):Output:
   0:0270:324:3 - iprt.4.0(DBG):================================
   0:0270:324:3 - iprt.4.0(DBG):cn:
   0:0270:324:3 - iprt.4.0(DBG):leg2: 0040611980110
   0:0270:324:3 - iprt.4.0(DBG):cgpn: 0040611980110
   0:0270:324:3 - iprt.4.0(DBG):cdpn: 100
   0:0270:324:3 - iprt.4.0(DBG):leg2-orig: 0
   0:0270:324:3 - iprt.4.0(DBG):================================


Here you can see what the incoming phone number looks like: This is exactly how it must be entered in the block list.

Setup
------

The app generates the following XML script, when adding a phone number to the blocklist app:

.. code-block:: xml

    <voicemail xmlns="http://www.innovaphone.com/xsd/voicemail6.xsd" _ver="VM-60114">

    </function>
    <function define="checkTrunk">

            <pbx-xfer e164="" name="loopback from trunk" />
            </case>
        </switch>
    </function>
    </voicemail>



.. note::
    As soon as there is a change, e.g. adding a phone number,
    the app extends the script automatically.
    The script cannot be customized. Manual changes are overwritten as soon as there are changes in the app.
