Call Forwarding
Call Forwarding for Groups
When call forwarding for groups is used, internal and external calls to a
group can be rerouted to other internal phones or external connections. In
this way, a person that is not a member of this group and therefore cannot
log in, can receive these calls.
Call forwarding for groups makes sure that someone is always available on
the group number, even if the calls cannot be taken by a member of the
group.
Note:
LCR will be used for call forwarding for groups to an external destination
(e.g., mobile phone) if at least one member of the group has LCR
enabled. It does not matter if the corresponding subscriber is logged in
or not.
When forwarding a group the option
As subscriber
in the exchange line
settings of the group is not considered. For call forwarding instead
exchange line authorisation is not restricted and no call restrictors and
call deblockers are used.
Preferred exchange line/Number Presentation: The number of the group
is always presented.
To avoid having to use a second call channel in the case of call
forwarding to an external destination, the PBX tries to reroute the call
directly at the network provider using call deflection. The following
requirements must be fulfilled for this purpose: 1. The incoming call was
made via an ISDN network provider supporting call deflection. 2. The
rerouted phone number is neither called as a group member, nor is it
required to consider parallel calling or fallback on busy.
