</div></div>You may have to reboot the router (or somehow flush the connection<br>
tracking table) to make it forget about any existing connection attempts.<br>
<br>
Of course some sip phones are "broken" or at least weird and unusual<br>
and don't work well with the sip nat handling in the kernel (generally<br>
things made by Cisco, but only a few models).<br>
<br>
The modules should be nf_nat_sip and nf_conntrack_sip.<br></blockquote><div><br></div><div>Ya I think it could be the phone, and the "router" is a linux box so flushing the tracking table should be possible</div>
