<DIV><FONT face=Arial size=2>I have a budgetone behind nat it registers with ser
fine. I can make a call from it to another non nat budgetone fine.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In the following scenario</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>budgeton(no nat) -> ser -> asterisk ->
........, things work fine</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>However in the following scenario</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>budgeton(nat) -> ser -> asterisk ->.....,
asterisk cannot authenticate the forwarded messages from ser</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I remove the authentication requirement from
asterisk there is no problem.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there a problem with forwarded authentication
when the phone registered with ser is behind nat?</FONT></DIV>
