client, but it failed.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">i defined a port mapping on the adsl modem
for udp/tcp 5060 ports to forward the packets to the openser installed

<div><font face="Arial" size="2">when i try to register to openser i
received a 408 request timeout message.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">i guess its due to external ip of the openser
