Switching a videophone call to a voice call (Caller)
The caller can switch to voice call during videophone call.
● If the handset of your party is the FOMA terminal supporting the call switch, "Voice phone change" can be selected
from the function menu during the videophone call and you can switch between the videophone and voice call. (This
function is available in communications between voice call and videophone call switchable terminals.)
● You can switch only when you are the caller.
● To enable the caller to switch the call, the receiver needs to set to display the indicator of switching the call
beforehand. → P.94

The caller can also switch a voice call to a videophone call. → P.56
It is possible to switch repeatedly between videophone call and voice call.
It takes about 5 seconds to switch the calls. Note that the signal quality may affect how long it takes.
You cannot switch the calls in the following cases:
・ You are the receiver of the call.
・ You make a call and the other party stops the call switch notification function.→ P.94
・ When the other party is holding a call or activating "Record message".
The call time displayed is reset to 0 second each time the calls are switched. However, after the switching operation, if the videophone
call is finished, the displayed call time is the total of voice call and videophone call.
The call may be canceled because of the failure of the switch from a videophone call to a voice call due to the signal quality or the
circumstances of the other party.
You are not charged while "SWITCHING VOICE/VIDEO" is displayed.
When the call is switched, the first dialed number is registered to the Redial/Dialed calls records. The first received number is
registered to the Received calls record.
If you perform the switching operation, the amount of call charge displayed in "Call data" (P.313) may differ from the one you will pay.
Changing to voice call cancels the hands-free setting.
