You did not tell us, which version of asterisk You are running.

The kernel restricts setting of high ToS-bits for non-root users. To
allow a process to run as non-root and be able to set these bits, there
is the possibility to use 'capabilities'. This feature was implemtented
and fixed in the past (issues 7074 and 14004 at issues.asterisk.org).

In case Your iptables is working, I think You can ignore the warning.
