<DIV><FONT face=Arial size=2>We have an Asterisk v1.2.16 box registering with an
ITSP<SPAN class=416113519-04052007> using SIP</SPAN>. The registration
succeeds, and is confirmed with SIP SHOW REGISTER. However, we
frequently (every few minutes) see this on our console:</FONT></DIV>

<DIV><SPAN class=416113519-04052007><FONT face=Arial size=2>1. What causes
the two register attempt messages above?</FONT></SPAN></DIV>2. Why is our
asterisk box being associated with the "entryunauthorized" context, not the
"entryinternal" context? (See below)</FONT></SPAN></DIV>
<DIV><SPAN class=416113519-04052007><FONT face=Arial size=2>3. Why is the
