When a videophone call is not connected, the cause 
of the failure appears.

z The cause may not appear depending on the 

situation.

z Depending on the type of the other party’s phone or 

network service subscription, the reason may not 
accurately reflect the other party’s actual status.

z If the videophone call is not supported, your call is 

automatically switched to a FOMA voice call when 
you set “Auto redial as voice” to “ON”. However, the 
videophone may not work properly if you call an 
ISDN synchronous 64 KB access point, 3G-324M-
incompatible ISDN videophone (as of October, 
2009) or if you dial a wrong number. Call charges 
may apply.

z You can use this function with terminals compatible 

with FOMA voice call/videophone call switch.

z You can switch calls only when you are the caller.
z To switch calls, the receiver needs to set “Ntfy 

switch-mode” beforehand.
