Check all sub call state to disable VT setting

If user makes a call with a non primary call sub, VT setting is not
disabled. Because these settings checks only call state of primary call
sub. All call sub should be checked and disable VT setting.

Test: manual - Verified that VT setting is disabled during non default
call sub calling.
