Amendment to "Call signalling and number assignment"
The section amends the sections "Accepting calls", "Web configurator – Assigning send and receive
numbers to handsets" and "Web configurator – Assigning receive numbers to the answering machine"
in the user guide for your Gigaset VoIP phone.
Signalling incoming calls
If you have not assigned any receive numbers, either to the answering machine or the reg-
istered handsets, calls to all connections will be signalled on all handsets.
If you have assigned receive numbers, your handset will only indicate calls to receiving
numbers assigned to this handset. Please note the following cases:
u If the phone number is not assigned to a handset or an answering machine as a receive
number, all calls to this number are signalled on all handsets.
u If the phone number is not assigned to a handset, but is assigned to the answering
machine, the call is not signalled on any handset and is accepted by the answering
machine.
u Calls to your phone's IP address are signalled on all handsets.
