Transferring to a Key Telephone
A call transferred to a key telephone is offered on the key telephone’s personal key or
on a line key. If the call comes from the public network, it is signalled with the external
ringing pattern.
Transferring to a key telephone with prior notice:
• If a call is transferred to a key telephone that is already receiving the call via a line
key, it is offered on both the personal key and the line key. The call can be answered
using either key.
– If the call is answered using the personal key, the user will be connected to the
transferring party.
– If the call is answered using the line key, the user will be connected to the caller.
• If a call is transferred to a key telephone that is not receiving the call via a line key, it
will be offered on the personal key only.
If the call is answered, the user will be connected to the transferring party.
