Hi<div>Is there anything like <span class="Apple-style-span" style="font-family: sans-serif; line-height: 38px; ">nat-options-ping and unregister-on-options-fail to use for all registered users (not just users behind nat)? cause sometimes the network connection between users and fs breaks and I don&#39;t want to send calls to those users.</span></div>
<div><span class="Apple-style-span" style="font-family: sans-serif; line-height: 38px; ">thanx</span></div>
