You need to set /proc/sys/fs/suid_dumpable to a non-zero value (see man 5 proc), to enable core dumping for processes
that switch their UID on startup (such as freeswitch with -u option).

By default, the freeswitch process will try to put the core file into the CWD (current work directory),
so make sure the UID it is running as can write there (or "cd" into a different directory before starting it).
You might also want to check out man 5 core, for all the other options (e.g. piping core dumps into a custom handler, with core_pattern).
