<BR><FONT SIZE=2>> Good morning Christian,</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> I agree with you that the reason "warm boot"</FONT>
<BR><FONT SIZE=2>> describes perfectly the state of the MG when it</FONT>
<BR><FONT SIZE=2>> upgrades to a new version of the H.248 protocol.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> I have question on the use of "restart" and</FONT>
<BR><FONT SIZE=2>> "root". According the RFC3015, this combination</FONT>
<BR><FONT SIZE=2>> indicates a registration command. Since the</FONT>
<BR><FONT SIZE=2>> registration command should be the first command</FONT>
<BR><FONT SIZE=2>> received from an MG after it comes in service,</FONT>
<BR><FONT SIZE=2>> what happens when this command is received while</FONT>
<BR><FONT SIZE=2>> the MG is already in service?</FONT>
</P>
<P><FONT SIZE=2>[PTT] The MGC must interpret it as meaning that the MG is reregistering after a warm boot.</FONT>
