Description
• Loopback Destination (Name or Number) to which calls are
forwarded, which dialled the same Trunk object. This is
typically used if the number of the Trunk object (e.g. 0)
shall be used as extension number to the switchboard for
incoming calls. If the Internal checkmark is set, this is
executed also if the trunk is called from within the PBX
with a calling party number matching the number of the
trunk object. This can happen if for example an escape is
configured for the node of the trunk object matching the
number of the trunk object.
• Incomplete Destination (Name or Number) to which calls are
forwarded, which dialled an incomplete number. If the
incoming call is enblock this can be determined
immediately. For overlap receiving calls a timeout of 4 s is
used. Sometimes it is desired that calls without extension
number are sent to the switchboard. In this case the
number of the switchboard should be configured here.
• Invalid Destination (Name or Number) to which calls are
forwarded, which dialled an invalid number. Typically the
number of the switchboard is configured here so that
incoming calls with an invalid extension are not lost.
• Busy Destination (Name or Number) to which calls are
forwarded, which dialled a busy number. If a CFB is
configured at a called user this takes precedence. A CFB
at the called user to a number - turns this off for this user.
•No Answer
Destination (Name or Number) to which calls are
forwarded, which dialled a destination which exists but
does not answer. There is no Timeout configurable for
this, instead the timeout value configured for CFNR is
used. If a CFNR is configured at a called user this takes
precedence.
• Reroute supported This check box turn on rerouting of incoming calls which
are diverted to the same Trunk object. Normally an
incoming call which is diverted to the same Trunk object is
sent out on the Trunk as a normal outgoing call. If this
option is checked a reroute request is sent out instead. If
the call is received from an ISDN interface this is mapped
to partial rerouting. By doing this no channel is used on
the ISDN interface for such a call (instead of 2) and the
original calling party number is sent to the final
destination by the ISDN network. Rerouting is supported
only for CFU and CFB, not for CFNR.
