Voice call transfer
The voice call transfer is a network service that
enables you to connect two voice calls together
and disconnect yourself from both calls.
Note:
The transfer operation can be made only if:
1. You have one call on hold.
2. You have one call active.
3. All calls are voice calls (fax or data calls
cannot be transferred).
4. None of the calls is a conference call.
There are two ways to transfer voice calls from
the phone interface:

press

Alternating calls
During an alternating call, you may change the
mode of the call from voice to fax. Alternating
calls can be made to a fax mailbox, for example:
you initiate the call as a voice call, but it changes
into a fax call when your fax mailbox starts to
send you your faxes.
To make alternating calls you need to add a spe-
cial Tel/Fax field to the contact cards of the ser-
vices of your alternating calls (see Chapter 3
"Contacts: Contact cards - Customizing contact
cards" on page 3-3).
You can also change a voice call into a fax call by
pressing
Change mode

be put on hold or incorporated into a conference
call.
