<p>Kamailio is acting at upper layer in the IP stack, so it is not required by specs to do any ICMP.  Otherwise, it can only add some delay in sending out, because UDP is retransmitted anyhow. Moreover, some hosts reject icmp by firewall/local policy, even if they accept sip on 5060.</p>
<p>If some one wants to make a pull request, that can be reviewed and merged. But there is no reason to have this on issues tracker. If someone think differently, add comments and can be reopen.</p>
