<DIV><FONT face=Verdana size=2>Hi,</FONT></DIV>
<DIV><BR><FONT face=Verdana size=2>I'm receiving 478 status for a REGISTER
sent to SER Proxy. I'm sending Register request URI in the form of
domain name. But 478 status code as given by SER is an invalid response as per
RFC 3261. </FONT></DIV>
<DIV><FONT face=Verdana size=2> When does SER responds
with status code 478?</FONT></DIV>
<DIV><FONT face=Verdana size=2>(Below is SIP register request packet and
response packet)<BR></FONT></DIV>
<DIV><FONT face=Verdana size=2>Is it configuration problem or any thing wrong in
my packet?<BR></FONT></DIV>
