Check "cat /proc/sys/kernel/core_pattern". It says the path and format of the 
Opensips init scripts sets it (/etc/init.d/opensips):

if test "$DUMP_CORE" = "yes" ; then
  # set proper ulimit
  ulimit -c unlimited

  # directory for the core dump files
  #[ -d $COREDIR ] || mkdir $COREDIR
  #chmod 777 $COREDIR
  echo "$COREDIR/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern  # <-- HERE

For that you need to set DUMP_CORE=yes in /etc/default/opensips (not sure if 
Fedora uses this location).

If the content of /proc/sys/kernel/core_pattern is just the default "core" 
then the coredump file is called "core" and it's located on the directory from 
where opensips was started (I hope).
