NTT docomo FOMA SO906i User Manual page 58

If you use the FOMA ter minal to place a
videophone call to emergency numbers (110,
119, and 118), it automatically switches to voice
call dialing.
When you place a videophone call to a terminal
that is not equipped with a videophone function,
or when a recipient is outside of the service area
or the phone is powered off (even if the FOMA
terminal has the videophone function), your call
is not connected. When you place a videophone
call to a terminal that is not equipped with a
videophone function and the Auto redial(voice) is
set to [ON], the recipient's terminal disconnects
your videophone call before it is connected, and
the FOMA terminal redials the call as a voice
call. If, however, you dial a wrong number such
as an ISDN synchronous 64kbps access points,
or ISDN videophone that is not 3G-324M (as of
April 2008) compatible, the above operations
may not take place. Note also that you may be
charged for the call.
